Member delay_at_max_brightness_for_power (uint16_t ms): This is now a part of CFastLED::delay()
File fastspi_dma.h: This header file is empty.
Member fl::fetch_update (): Use fl::async_run() instead - this calls async_run() internally
Member fl::PromiseResult: Use result<T> instead of PromiseResult<T>
Member set_max_power_in_milliwatts (uint32_t powerInmW): Use CFastLED::setMaxPowerInMilliWatts
Member set_max_power_in_volts_and_milliamps (uint8_t volts, uint32_t milliamps): Use CFastLED::setMaxPowerInVoltsAndMilliamps()
Member show_at_max_brightness_for_power (): This is now a part of CFastLED::show()
