Implementations§

source§

impl Spi2DmaChannelCreator

source

pub fn configure<'a>( self, burst_mode: bool, tx_descriptors: &'a mut [u32], rx_descriptors: &'a mut [u32], priority: DmaPriority ) -> Channel<'a, Spi2DmaChannel>

Configure the channel for use

Descriptors should be sized as ((CHUNK_SIZE + 4091) / 4092) * 3. I.e., to transfer buffers of size 1..=4092, you need 3 descriptors. The number of descriptors must be a multiple of 3.
