Francisco	4dce666435	Merge pull request #14764 from hugueslarrive/cpu/stm32/periph/dma ... cpu/stm32/periph/dma: add support for STM32F3	2020-08-19 12:53:35 +02:00
hugues	2f0ac9e820	cpu/stm32/periph/spi: use dma_stop for STM32s that need it	2020-08-19 11:25:34 +02:00
Koen Zandberg	b9d62e47d3	stm32: Add support for arbitrary SPI clock rates	2020-08-18 16:55:01 +02:00
Koen Zandberg	29739be13a	stm32/spi: Use new DMA setup/prepare functions	2020-06-09 10:20:50 +02:00
Koen Zandberg	b7d0cbcd57	stm32/spi: Remove superfluous DMA stop call ... The DMA stream will automatically disable itself as soon as the transfer is finished. No need to do this an additional time after the transfer is finished	2020-06-09 10:20:49 +02:00
Koen Zandberg	fddf0897e8	stm32/spi: Acquire/release the DMA during the SPI acquire/release	2020-06-09 10:20:49 +02:00
Koen Zandberg	3a8dd32265	stm32/spi: Reduce register writes in hot path ... This combines a number of register writes in the SPI acquire and transfer code. The DMA enable for SPI is moved to the acquire function, switching between DMA and regular transfer between acquires is not possible.	2020-06-09 10:20:49 +02:00
