Followed a similar thread with SPI Rx Slave in
followed the same, but used Channel 3 instead..
The RM0364, DocID025177 Rev 2, Page #179, Figure 20. STM32F334xx DMA1 request mapping,
states that DMA1 Channel 3 needs remapping to be used with SPI1. It appears to be the same for
any DMA Channel.
Nevertheless it appears that all SPI TX DMA transfers do need a DMA remap, according to the
figure 20. But well, that aside ..
Though I tried remap, there appears to be no change. I have connected a scope to the SCK pin,
there appears to be no activity at all.
Any thoughts, on the following code ?
