Hello,
I have a SPI TX DMA,
and I need to do the following
- Step 1:start the TX DMA ,
- Step 2:stop the DMA,
- Step 3: store the NDTR register,
- Step 4: modify the size of the DMA SPI
- Step 5: restart the DMA with the new size
- Step 6: and restore the position of the NDTR register to continue (restart) at the same position as previously
I guess the last step (6) is not possible ? right ? or is there a way to change the current position
I tried to change it using the __HAL_SET_COUNTER but it is not working
Do I miss something ?
Vincent
