SPI and DMA transfer
2011-05-17 03:42 AM
Hi, i have a Problem with a not correct working SPI Transfer.
I use DMA Transfer to load the data register and fetch the rx-data. Furthermore i use hardware nss because i hoped, that the DMA_Channel3->CNDTR register is reset to initial value when NSS is disabled. But this doesnt seem to be the case? So a lost clock or a clock to much has impact on all further transmissions?! does someone have a solution?
