- Enabled support for IDF4.4 and above
- with RMT backend only
- Added API
led_strip_set_pixel_hsv
- Support configurable SPI mode to control leds
- recommend enabling DMA when using SPI mode
- Support configurable RMT channel size by setting
mem_block_symbols
- Support for 4 components RGBW leds (SK6812):
- in led_strip_config_t new fields led_pixel_format, controlling byte format (LED_PIXEL_FORMAT_GRB, LED_PIXEL_FORMAT_GRBW) led_model, used to configure bit timing (LED_MODEL_WS2812, LED_MODEL_SK6812)
- new API led_strip_set_pixel_rgbw
- new interface type set_pixel_rgbw
- Support DMA feature, which offloads the CPU by a lot when it comes to drive a bunch of LEDs
- Support various RMT clock sources
- Acquire and release the power management lock before and after each refresh
- New driver flag:
invert_out
which can invert the led control signal by hardware
- Reimplemented the driver using the new RMT driver (
driver/rmt_tx.h
)
- Initial driver version, based on the legacy RMT driver (
driver/rmt.h
)
