The chip passes on the remaining data to the next LED, allowing them to be chained together. In this way, you can easily control the color of the individual LEDs. +## Supported Driver Types + +| | AVR | ARM | +|----------|--------------------|--------------------| +| bit bang | :heavy_check_mark: | :heavy_check_mark: | +| I2C | :heavy_check_mark: | | +| SPI | | Soon™ | +| PWM | | Soon™ | + ## Driver configuration ### Bitbang @@ -17,7 +26,7 @@ Default driver, the absence of configuration assumes this driver.
