Posted on February 05, 2016 at 17:50Hello, I'm using SPI in RXOnly mode with DMA transfers. If I setup DMA to transfer 7 bytes, it does so correctly and it triggers TC interrupt, but the clock never stops and this forces the data to continue to stre...
Posted on February 09, 2016 at 22:26I'm working with the Nucleo-F303RE development board, and am having a hard time communicating accurately with the board. I have it attached to an ADC that can communicate over SPI. The ADC outputs a 16-bit word co...
