2020-08-29Fix DMA stream ID calculation in ws2812_pwm (#10008)Gravatar Sergey Vlasov
Some STM32 chips have STM32_DMA1_STREAM1 as the first DMA stream, others (F4xx, F7xx, H7xx) have STM32_DMA1_STREAM0. Instead of those names, use STM32_DMA_STREAM(0), which should always give the first stm32_dma_stream_t structure in the DMA streams array, so that the stream ID would be calculated correctly.
