+- Minimal memory footprint (2 buffers only)
+- ESP32 platform exclusive
+
+## Quick Start
+
+```cpp
+#include "TasmotaLED.h"
+#include "TasmotaLEDPusher.h"
+
+// Create 60-LED WS2812 strip on GPIO 5
+TasmotaLED strip(ws2812_grb, 60);
+
+void setup() {
+  TasmotaLEDPusher *pusher = TasmotaLEDPusher::Create(TasmotaLed_HW_Default, 5);
+  strip.SetPusher(pusher);
+  strip.Begin();
+  
+  // Set colors and display
+  strip.ClearTo(0xFF0000);  // All red
+  strip.Show();
+}
+```

+### Hardware Support
+
+| Hardware | ESP32 | ESP32-S2 | ESP32-S3 | ESP32-C3 | ESP32-C2 | ESP32-C6 |
+|----------|-------|----------|----------|----------|----------|----------|
+| **RMT**  | ✅    | ✅       | ✅       | ✅       | ❌       | ✅       |
+| **SPI**  | ✅    | ✅       | ✅       | ✅       | ✅       | ✅       |
+| **I2S**  | ✅    | ✅       | ✅       | ❌       | ❌       | ❌       |
+
+**Selection Priority:** RMT → I2S → SPI (auto-selected based on SOC capabilities)
+
+## Configuration
+
+### LED Type Encoding
+
+LED types are encoded in a 16-bit value:
+
+```
+Bits 15-8: Timing (WS2812=0, SK6812=1)
+Bit  7:    W Position (0=after RGB, 1=before RGB)
+Bits 6-4:  Pixel Order (GRB, RGB, BGR, etc.)
+Bits 3-0:  Bytes/Pixel (3=RGB, 4=RGBW)
+```
+
+**Predefined Types:**
+```cpp
+ws2812_grb   // WS2812 with GRB ordering (most common)
+sk6812_grbw  // SK6812 with GRBW ordering
+sk6812_grb   // SK6812 with GRB ordering (no white)
+```
+
+**Custom Types:**
+```cpp
+uint16_t custom = TasmotaLed_3_RGB |      // 3 bytes per pixel
+                  TasmotaLed_RGB |        // RGB ordering
+                  TasmotaLed_WS2812;      // WS2812 timing
+```
+
+### Pixel Ordering Options
+
+| Enum | Order | Description |
+|------|-------|-------------|
+| `TasmotaLed_GRB` | G, R, B | Green-Red-Blue (default) |
+| `TasmotaLed_RGB` | R, G, B | Red-Green-Blue |
+| `TasmotaLed_BGR` | B, G, R | Blue-Green-Red |
+| `TasmotaLed_RBG` | R, B, G | Red-Blue-Green |
+| `TasmotaLed_BRG` | B, R, G | Blue-Red-Green |
+| `TasmotaLed_GBR` | G, B, R | Green-Blue-Red |
+
+## Timing Specifications
+
+### WS2812 Timing
+```
+T0H:  400ns  (bit 0 high time)
+T0L:  850ns  (bit 0 low time)
+T1H:  800ns  (bit 1 high time)
+T1L:  450ns  (bit 1 low time)
+Reset: 80µs  (reset pulse)
+```
+
+### SK6812 Timing
+```
+T0H:  300ns  (bit 0 high time)
+T0L:  900ns  (bit 0 low time)
+T1H:  600ns  (bit 1 high time)
+T1L:  600ns  (bit 1 low time)
+Reset: 80µs  (reset pulse)
+```
+
+### RMT Implementation
+- Clock: 40 MHz (25ns resolution)
+- Precision: ±25ns per timing parameter
+- Memory: 192 symbols per channel
+- Non-blocking with DMA
+
+### SPI Implementation
+- Clock: 2.5 MHz
+- Encoding: 3 SPI bits per LED bit
+- Bit 0: `100` pattern
+- Bit 1: `110` pattern
+- Memory: 3× pixel buffer size
+
+## Memory Usage
+
+| Configuration | Memory Required |
+|---------------|-----------------|
+| 60 RGB pixels | ~460 bytes |
+| 144 RGB pixels | ~964 bytes |
+| 300 RGB pixels | ~1,900 bytes |
+| 512 RGB pixels | ~3,172 bytes |
+| 60 RGBW pixels | ~580 bytes |
+
+**Formula:** `~100 bytes + (2 × pixels × bytes_per_pixel)`
+
+**SPI Additional:** Add `3 × pixels × bytes_per_pixel` for encoding buffer
+
+## Performance
+
+### Transmission Times (WS2812/SK6812)
+- 60 pixels: ~1.8 ms (max 555 Hz)
+- 144 pixels: ~4.3 ms (max 232 Hz)
+- 300 pixels: ~9.0 ms (max 111 Hz)
+- 512 pixels: ~15.4 ms (max 65 Hz)
+
+### CPU Overhead
+- **RMT:** <1% during transmission (DMA-based)
+- **SPI:** <2% during transmission (DMA-based)
+- **Format conversion:** ~124 µs for 512 RGB pixels
+

+## Architecture Overview
+
+### Design Philosophy
+
+TasmotaLED is designed with the following principles:
+
+1. **Minimal Memory Footprint**: Uses only two buffers (work and show) with no buffer swapping overhead
+2. **Hardware Acceleration First**: Leverages ESP32's RMT, SPI, or I2S peripherals for precise timing
+3. **Zero-Copy Operations**: Direct buffer manipulation without intermediate copies
+4. **NeoPixelBus Compatibility**: Similar API for easy migration from NeoPixelBus
+5. **Compile-Time Optimization**: Hardware support can be selectively enabled/disabled

+
+
+### Memory Management
+
+TasmotaLED uses a dual-buffer system:
+
+1. **Work Buffer (`_buf_work`)**: 
+   - Directly accessible by application
+   - Stores pixels in WRGB or RGB format (0xWWRRGGBB or 0xRRGGBB)
+   - Can be modified at any time
+   - Size: `pixel_count × pixel_size` bytes
+
+2. **Show Buffer (`_buf_show`)**:
+   - Internal buffer for hardware transmission
+   - Stores pixels in LED strip format (e.g., GRB, GRBW)
+   - Populated during `Show()` call with format conversion
+   - Size: `pixel_count × pixel_size` bytes
+
+**Memory Allocation Example:**
+- 512 RGB pixels: 2 × 512 × 3 = 3,072 bytes (~3 KB)
+- 512 RGBW pixels: 2 × 512 × 4 = 4,096 bytes (~4 KB)

+## Hardware Acceleration
+
+### Hardware Support Matrix
+
+| Hardware | ESP32 | ESP32-S2 | ESP32-S3 | ESP32-C3 | ESP32-C2 | ESP32-C6 |
+|----------|-------|----------|----------|----------|----------|----------|
+| **RMT** | ✅ | ✅ | ✅ | ✅ | ❌ | ✅ |
+| **SPI** | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
+| **I2S** | ✅ | ✅ | ✅ | ❌ | ❌ | ❌ |
+
+### Hardware Selection
+
+Hardware acceleration is selected using the `TasmotaLEDHardware` enum:
+
+```cpp
+enum TasmotaLEDHardware : uint32_t {
+  TasmotaLed_HW_Default = 0x000000,  // Auto-select best available
+  TasmotaLed_RMT  = (1 << 0) << 16,  // 0x010000 - RMT peripheral
+  TasmotaLed_SPI  = (1 << 1) << 16,  // 0x020000 - SPI peripheral
+  TasmotaLed_I2S  = (1 << 2) << 16,  // 0x040000 - I2S peripheral
+  TasmotaLed_HW_None = 0xFF << 16,   // 0xFF0000 - No hardware support
+};
+```
+
+### Hardware Resolution Priority
+
+When `TasmotaLed_HW_Default` is specified, the library selects hardware in this order:
+
+1. **RMT** (if available) - Preferred for precision and low CPU overhead
+2. **I2S** (if available) - Good for large strips
+3. **SPI** (if available) - Fallback option, works on all ESP32 variants
+
+### Compile-Time Configuration
+
+Hardware support can be enabled/disabled at compile time:
+
+```cpp
+// In your build configuration or before including TasmotaLED
+#define TASMOTALED_HARDWARE_RMT 1  // Enable RMT (default: 1)
+#define TASMOTALED_HARDWARE_I2S 0  // Enable I2S (default: 0)
+#define TASMOTALED_HARDWARE_SPI 0  // Enable SPI (default: 0)
+```
+
+**Note:** If no hardware is explicitly enabled, SPI is automatically enabled as fallback.
+
+### RMT Implementation
+
+**Advantages:**
+- Precise timing control (25ns resolution at 40MHz)
+- Low CPU overhead
+- Non-blocking operation with DMA
+- Supports up to 8 channels (ESP32) or 4 channels (ESP32-S2/S3/C3)
+
+**Technical Details:**
+- Clock resolution: 40 MHz (25ns per tick)
+- Memory block: 192 symbols (768 bytes)
+- Transaction queue depth: 4
+- Encoder: Custom LED strip encoder with bit-level control
+
+**Timing Precision:**
+```
+WS2812: T0H=400ns (16 ticks), T0L=850ns (34 ticks)
+        T1H=800ns (32 ticks), T1L=450ns (18 ticks)
+        Reset=80µs (3200 ticks)
+
+SK6812: T0H=300ns (12 ticks), T0L=900ns (36 ticks)
+        T1H=600ns (24 ticks), T1L=600ns (24 ticks)
+        Reset=80µs (3200 ticks)
+```
+
+### SPI Implementation
+
+**Advantages:**
+- Available on all ESP32 variants
+- Works on ESP32-C2 (no RMT support)
+- Reliable fallback option
+
+**Technical Details:**
+- Clock frequency: 2.5 MHz
+- Each LED bit encoded as 3 SPI bits
+- Bit encoding: `0` = `100`, `1` = `110`
+- DMA support: Optional (auto-selected)
+- Memory overhead: 3× pixel buffer size
+
+**Bit Encoding:**
+```
+LED bit 0: SPI bits 100 (high for 400ns, low for 800ns at 2.5MHz)
+LED bit 1: SPI bits 110 (high for 800ns, low for 400ns at 2.5MHz)
+```
+
+### I2S Implementation
+
+**Status:** Planned but not yet implemented
+
+**Advantages:**
+- Very high throughput
+- Excellent for large LED installations
+- Parallel data transmission

+## Configuration Guide
+
+### Basic Setup
+
+#### Step 1: Include Headers
+
+```cpp
+#include "TasmotaLED.h"
+#include "TasmotaLEDPusher.h"
+```
+
+#### Step 2: Create Strip Instance
+
+```cpp
+// For WS2812 RGB strip with 60 LEDs
+TasmotaLED strip(ws2812_grb, 60);
+
+// For SK6812 RGBW strip with 100 LEDs
+TasmotaLED strip(sk6812_grbw, 100);
+
+// Custom configuration
+uint16_t custom_type = TasmotaLed_3_RGB | TasmotaLed_RGB | TasmotaLed_WS2812;
+TasmotaLED strip(custom_type, 144);
+```
+
+#### Step 3: Create and Assign Pusher
+
+```cpp
+// Auto-select best hardware for GPIO 5
+TasmotaLEDPusher *pusher = TasmotaLEDPusher::Create(TasmotaLed_HW_Default, 5);
+if (pusher) {
+  strip.SetPusher(pusher);
+} else {
+  // Handle error
+}
+
+// Or explicitly request RMT
+TasmotaLEDPusher *pusher = TasmotaLEDPusher::Create(TasmotaLed_RMT, 5);
+```
+
+#### Step 4: Initialize
+
+```cpp
+if (!strip.Begin()) {
+  // Handle initialization error
+  Serial.println("Failed to initialize LED strip");
+}
+```
+
+#### Step 5: Use the Strip
+
+```cpp
+// Set colors
+strip.ClearTo(0x000000);           // Clear to black
+strip.SetPixelColor(0, 0xFF0000);  // First pixel red
+strip.SetPixelColor(1, 0x00FF00);  // Second pixel green
+strip.Show();                       // Update strip
+```
+
+### Advanced Configuration
+
+#### Custom LED Type
+
+```cpp
+// Create custom type: RGB, BGR ordering, WS2812 timing
+uint16_t custom_type = TasmotaLed_3_RGB |      // 3 bytes per pixel
+                       TasmotaLed_BGR |        // BGR ordering
+                       TasmotaLed_WS2812;      // WS2812 timing
+
+TasmotaLED strip(custom_type, 60);
+```
+
+#### RGBW with W Channel First
+
+```cpp
+// SK6812 RGBW with W channel before RGB
+uint16_t rgbw_type = TasmotaLed_4_WRGB |       // 4 bytes per pixel
+                     TasmotaLed_RGB |          // RGB ordering
+                     TasmotaLed_Wxxx |         // W first
+                     TasmotaLed_SK6812;        // SK6812 timing
+
+TasmotaLED strip(rgbw_type, 100);
+```
+
+#### Multiple Strips
+
+```cpp
+// Strip 1 on GPIO 5
+TasmotaLED strip1(ws2812_grb, 60);
+TasmotaLEDPusher *pusher1 = TasmotaLEDPusher::Create(TasmotaLed_RMT, 5);
+strip1.SetPusher(pusher1);
+strip1.Begin();
+
+// Strip 2 on GPIO 18
+TasmotaLED strip2(sk6812_grbw, 100);
+TasmotaLEDPusher *pusher2 = TasmotaLEDPusher::Create(TasmotaLed_RMT, 18);
+strip2.SetPusher(pusher2);
+strip2.Begin();
+```
+
+#### Raw Format Mode
+
+```cpp
+strip.SetRawFormat(true);  // Disable automatic format conversion
+
+// Now buffer must be in strip's native format (e.g., GRB for WS2812)
+uint8_t *buf = strip.Pixels();
+buf[0] = 0xFF;  // Green
+buf[1] = 0x00;  // Red
+buf[2] = 0x00;  // Blue
+strip.Show();
+```
+
+### Compile-Time Configuration
+
+#### Enable/Disable Hardware Support
+
+In your `platformio.ini` or build flags:
+
+```ini
+build_flags = 
+  -DTASMOTALED_HARDWARE_RMT=1
+  -DTASMOTALED_HARDWARE_SPI=1
+  -DTASMOTALED_HARDWARE_I2S=0
+```
+
+Or in your code before including TasmotaLED:
+
+```cpp
+#define TASMOTALED_HARDWARE_RMT 1
+#define TASMOTALED_HARDWARE_SPI 0
+#define TASMOTALED_HARDWARE_I2S 0
+
+#include "TasmotaLED.h"

+- **Setup:** ~100 µs (one-time)
+- **Per Show():** ~150 µs (format conversion + DMA setup)
+- **During transmission:** Near zero (DMA handles transfer)
+- **CPU usage:** <1% during transmission
+
+#### SPI Implementation
+- **Setup:** ~200 µs (one-time)
+- **Per Show():** ~550 µs (encoding + format conversion)
+- **During transmission:** Near zero (DMA handles transfer)
+- **CPU usage:** <2% during transmission
+
+### Optimization Tips
+
+1. **Minimize Show() Calls**
+   ```cpp
+   // Bad: Multiple Show() calls
+   for (int i = 0; i < 60; i++) {
+     strip.SetPixelColor(i, color);
+     strip.Show();  // 60 transmissions!
+   }
+   
+   // Good: Single Show() call
+   for (int i = 0; i < 60; i++) {
+     strip.SetPixelColor(i, color);
+   }
+   strip.Show();  // 1 transmission
+   ```
+
+2. **Use ClearTo() for Bulk Operations**
+   ```cpp
+   // Faster than loop with SetPixelColor()
+   strip.ClearTo(0xFF0000, 0, 29);  // First 30 pixels red
+   ```
+
+3. **Check CanShow() Before Show()**
+   ```cpp
+   if (strip.CanShow()) {
+     strip.Show();
+   }
+   ```
+
+4. **Direct Buffer Access for Complex Patterns**
+   ```cpp
+   uint8_t *buf = strip.Pixels();
+   // Direct manipulation (advanced)
+   for (int i = 0; i < strip.PixelCount() * strip.PixelSize(); i++) {
+     buf[i] = pattern[i];
+   }
+   strip.Show();
+   ```
+

+
+## Usage Examples
+
+### Basic Initialization
+
+```cpp
+#include "TasmotaLED.h"
+#include "TasmotaLEDPusher.h"
+
+// Create strip instance
+TasmotaLED strip(ws2812_grb, 60);
+
+void setup() {
+  // Create pusher with auto hardware selection
+  TasmotaLEDPusher *pusher = TasmotaLEDPusher::Create(TasmotaLed_HW_Default, 5);
+  if (pusher) {
+    strip.SetPusher(pusher);
+    if (strip.Begin()) {
+      // Strip ready
+      strip.ClearTo(0x000000);  // Clear to black
+      strip.Show();
+    }
+  }
+}
+```
+
+### Setting Pixels
+
+```cpp
+// Set individual pixels
+strip.SetPixelColor(0, 0xFF0000);   // Red
+strip.SetPixelColor(1, 0x00FF00);   // Green
+strip.SetPixelColor(2, 0x0000FF);   // Blue
+
+// Set range of pixels
+strip.ClearTo(0xFF0000, 0, 9);      // First 10 pixels red
+
+// Update strip
+strip.Show();
+```
+
+### RGBW Control
+
+```cpp
+TasmotaLED strip(sk6812_grbw, 60);
+
+// Pure white using W channel
+strip.ClearTo(0xFF000000);  // W=0xFF, RGB=0
+
+// Warm white (W + Red)
+strip.ClearTo(0x80FF0000);  // W=0x80, R=0xFF, G=0, B=0
+
+// RGB color (no W)
+strip.ClearTo(0x00FF00FF);  // W=0, R=0xFF, G=0, B=0xFF (Magenta)
+
+strip.Show();
+```
+
+### Non-Blocking Updates
+
+```cpp
+void loop() {
+  // Check if strip is ready before updating
+  if (strip.CanShow()) {
+    // Update pixels
+    for (int i = 0; i < strip.PixelCount(); i++) {
+      strip.SetPixelColor(i, colors[i]);
+    }
+    strip.Show();
+  }
+  
+  // Other code continues without blocking
+}
+```

+
+## Integration with Tasmota
+
+### Tasmota Light Driver Integration
+
+TasmotaLED is designed to integrate seamlessly with Tasmota's light driver system. Here's how it fits into the Tasmota architecture:
+
+#### Integration Points
+
+1. **Driver Initialization (FUNC_INIT)**
+   ```cpp
+   void TasmotaLEDInit(void) {
+     // Create strip based on Settings
+     uint16_t led_type = Settings->light_type;
+     uint16_t led_count = Settings->light_pixels;
+     int8_t gpio = Pin(GPIO_LED);
+     
+     strip = new TasmotaLED(led_type, led_count);
+     
+     // Create pusher with hardware auto-selection
+     TasmotaLEDPusher *pusher = TasmotaLEDPusher::Create(
+       TasmotaLed_HW_Default, gpio);
+     
+     if (pusher) {
+       strip->SetPusher(pusher);
+       if (strip->Begin()) {
+         AddLog(LOG_LEVEL_INFO, "LED: Initialized %d pixels on GPIO %d", 
+                led_count, gpio);
+       }
+     }
+   }
+   ```
+
+2. **Pixel Updates (FUNC_SET_CHANNELS)**
+   ```cpp
+   void TasmotaLEDUpdate(void) {
+     // Get color data from Tasmota light engine
+     for (int i = 0; i < strip->PixelCount(); i++) {
+       uint32_t color = GetPixelColorFromLightEngine(i);
+       strip->SetPixelColor(i, color);
+     }
+     
+     // Push to hardware
+     if (strip->CanShow()) {
+       strip->Show();
+     }
+   }
+   ```
+
+3. **Configuration Changes**
+   ```cpp
+   void TasmotaLEDReconfigure(void) {
+     // Handle pixel count changes
+     if (new_pixel_count != strip->PixelCount()) {
+       strip->SetPixelCount(new_pixel_count);
+     }
+     
+     // Handle type changes
+     if (new_led_type != strip->GetType()) {
+       strip->SetPixelSubType(new_led_type & 0xFF);
+     }
+   }
+   ```
+
+### Tasmota Commands
+
+When integrated with Tasmota, these commands control the LED strip:
+
+| Command | Description | Example |
+|---------|-------------|---------|
+| `Pixels` | Set number of LEDs | `Pixels 60` |
+| `Scheme` | Set color scheme | `Scheme 2` |
+| `Speed` | Set animation speed | `Speed 10` |
+| `Width` | Set effect width | `Width 1` |
+| `Color` | Set RGB color | `Color #FF0000` |
+| `White` | Set white channel | `White 50` |
+| `Dimmer` | Set brightness | `Dimmer 75` |
+| `Fade` | Enable fade | `Fade 1` |
+
+### Settings Storage
+
+Tasmota stores LED configuration in Settings structure:
+
+```cpp
+struct SETTINGS {
+  // ...
+  uint16_t light_pixels;        // Number of LEDs
+  uint8_t  light_type;          // LED type encoding
+  uint8_t  light_scheme;        // Animation scheme
+  uint8_t  light_speed;         // Animation speed
+  uint8_t  light_width;         // Effect width
+  // ...
+};
+```
+
+### Hardware Selection in Tasmota
+
+Tasmota automatically selects the best hardware based on:
+
+1. **SOC Capabilities**: Checks what hardware is available
+2. **GPIO Availability**: Ensures GPIO is not in use
+3. **Performance Requirements**: Selects RMT for best performance
+4. **Fallback**: Uses SPI if RMT unavailable
+
+```cpp
+uint32_t TasmotaSelectHardware(void) {
+  uint32_t hw = TasmotaLed_HW_Default;
+  
+  // Force SPI on ESP32-C2 (no RMT)
+  #ifdef CONFIG_IDF_TARGET_ESP32C2
+    hw = TasmotaLed_SPI;
+  #endif
+  
+  // User override via SetOption
+  if (Settings->flag5.led_use_spi) {
+    hw = TasmotaLed_SPI;
+  }
+  
+  return hw;
+}
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Strip Not Lighting Up
+
+**Symptoms:** No LEDs light up after calling `Show()`
+
+**Possible Causes:**
+- Pusher not initialized
+- Wrong GPIO pin
+- Incorrect LED type
+- Power supply issues
+
+**Solutions:**
+```cpp
+// Check initialization
+if (!strip.Begin()) {
+  Serial.println("Failed to initialize");
+  // Check pusher creation
+  if (pusher == nullptr) {
+    Serial.println("Pusher creation failed");
+  }
+}
+
+// Verify GPIO
+Serial.printf("Using GPIO %d\n", gpio_pin);
+
+// Test with simple pattern
+strip.ClearTo(0xFF0000);  // All red
+strip.Show();
+```
+
+#### 2. Wrong Colors
+
+**Symptoms:** Colors appear incorrect (e.g., red shows as green)
+
+**Possible Causes:**
+- Incorrect pixel ordering
+- Wrong LED type
+
+**Solutions:**
+```cpp
+// Try different orderings
+strip.SetPixelSubType(TasmotaLed_3_RGB | TasmotaLed_RGB);  // RGB
+strip.SetPixelSubType(TasmotaLed_3_RGB | TasmotaLed_GRB);  // GRB
+strip.SetPixelSubType(TasmotaLed_3_RGB | TasmotaLed_BGR);  // BGR
+
+// Test each ordering
+strip.ClearTo(0xFF0000);  // Should be red
+strip.Show();
+```
+
+#### 3. Flickering or Glitches
+
+**Symptoms:** Random flickering, incorrect colors, or partial updates
+
+**Possible Causes:**
+- Timing issues
+- Insufficient power
+- Long cable runs
+- Electromagnetic interference
+
+**Solutions:**
+```cpp
+// Try different timing
+uint16_t type_ws2812 = TasmotaLed_3_RGB | TasmotaLed_GRB | TasmotaLed_WS2812;
+uint16_t type_sk6812 = TasmotaLed_3_RGB | TasmotaLed_GRB | TasmotaLed_SK6812;
+
+// Check power supply (5V, sufficient amperage)
+// Add capacitor (1000µF) across power supply
+// Keep data cable short (<1m) or use level shifter
+```
+
+#### 4. Memory Allocation Failures
+
+**Symptoms:** `Begin()` returns false, crashes, or resets
+
+**Possible Causes:**
+- Too many LEDs for available memory
+- Memory fragmentation
+
+**Solutions:**
+```cpp
+// Check available heap
+Serial.printf("Free heap: %d bytes\n", ESP.getFreeHeap());
+
+// Calculate required memory
+uint32_t required = strip.PixelCount() * strip.PixelSize() * 2;
+Serial.printf("Required: %d bytes\n", required);
+
+// Reduce pixel count if necessary
+if (required > ESP.getFreeHeap() / 2) {
+  strip.SetPixelCount(smaller_count);
+}
+```
+
+#### 5. Performance Issues
+
+**Symptoms:** Slow updates, low frame rate
+
+**Possible Causes:**
+- Too many `Show()` calls
+- Inefficient pixel updates
+- Wrong hardware selection
+
+**Solutions:**
+```cpp
+// Batch updates
+for (int i = 0; i < strip.PixelCount(); i++) {
+  strip.SetPixelColor(i, colors[i]);
+}
+strip.Show();  // Single show call
+
+// Use ClearTo() for bulk operations
+strip.ClearTo(0xFF0000, 0, 29);  // Faster than loop
+
+// Check hardware
+Serial.printf("Using hardware: 0x%08X\n", hw_type);
+
+// Verify CanShow() before Show()
+if (strip.CanShow()) {
+  strip.Show();
+}
+```
+
+### Debug Logging
+
+Enable debug logging to diagnose issues:
+
+```cpp
+// In Tasmota, set log level
+SerialLog 4  // Debug level
+
+// Look for these messages:
+// LED: RMT gpio 5
+// LED: SPI gpio 5
+// LED: Error create RMT bus failed 5 err=XXX
+```
+
+### Hardware-Specific Issues
+
+#### ESP32-C2
+- Only SPI supported (no RMT)
+- Ensure `TASMOTALED_HARDWARE_SPI` is enabled
+
+#### ESP32-S2/S3
+- RMT channels limited to 4
+- Check channel availability if using multiple strips
+
+#### ESP32 Classic
+- RMT channels limited to 8
+- Most flexible hardware support
+
+### Timing Verification
+
+Verify timing with oscilloscope or logic analyzer:
+
+**WS2812 Expected:**
+- T0H: 400ns ±150ns
+- T0L: 850ns ±150ns
+- T1H: 800ns ±150ns
+- T1L: 450ns ±150ns
+- Reset: >50µs
+
+**SK6812 Expected:**
+- T0H: 300ns ±150ns
+- T0L: 900ns ±150ns
+- T1H: 600ns ±150ns
+- T1L: 600ns ±150ns
+- Reset: >80µs

+
+## Appendix
+
+### Pixel Order Matrix
+
+The library uses a lookup table for pixel ordering:
+
+```cpp
+static const uint8_t TASMOTALED_CHANNEL_ORDERS[8][3] = {
+  {1, 0, 2},  // Def=GRB (0)
+  {1, 0, 2},  // GRB (1)
+  {0, 1, 2},  // RGB (2)
+  {0, 2, 1},  // RBG (3)
+  {2, 1, 0},  // BRG (4)
+  {1, 2, 0},  // BGR (5)
+  {2, 0, 1},  // GBR (6)
+  {1, 0, 2}   // GRB (7) - fallback
+};
+```
+
+**Interpretation:**
+- Index 0: Position of Red channel
+- Index 1: Position of Green channel
+- Index 2: Position of Blue channel
+
+**Example:** GRB ordering `{1, 0, 2}` means:
+- Red goes to position 1
+- Green goes to position 0
+- Blue goes to position 2
+- Result: G(0) R(1) B(2)
+
+### Timing Structure
+
+```cpp
+typedef struct TasmotaLED_Timing {
+  uint16_t T0H;    // Bit 0 high time (nanoseconds)
+  uint16_t T0L;    // Bit 0 low time (nanoseconds)
+  uint16_t T1H;    // Bit 1 high time (nanoseconds)
+  uint16_t T1L;    // Bit 1 low time (nanoseconds)
+  uint32_t Reset;  // Reset time (nanoseconds)
+} TasmotaLED_Timing;
+```
