LL SPI_TwoBoards_FullDuplex_DMA_Master_Init examples #4

Closed phryniszak closed 4 years ago

phryniszak commented 4 years ago

In SPI_TwoBoards_FullDuplex_DMA_Master_Init examples SPI1_RX is connected to DMA1_Channel1 and SPI1_TX is connected to DMA1_Channel3, but in code DMA channel 3 is reporting DMA1_ReceiveComplete_Callback and DMA channel 1 DMA1_TransmitComplete_Callback.

The same here: LL_DMA_SetDataLength(DMA1, LL_DMA_CHANNEL_3, ubNbDataToReceive); LL_DMA_SetDataLength(DMA1, LL_DMA_CHANNEL_1, ubNbDataToTransmit);

To set transmit size we use ubNbDataToReceive and to receive ubNbDataToTransmit.

Examples are executing ok but naming is at least confusing.
