Has anyone gotten I2S in full duplex mode on the STM32F405 working?? I just can't seem to get the RX DMA to work. After initializing with the below code the TX DMA IRQs fire and that part works fine but I never...
Posted on August 09, 2013 at 00:46Here's the situation - I'm transferring some data from I2S to a buffer in memory via DMA. The DMA is set up to be double buffered - I'll skip all the initialization code but here are what the DMA registers look lik...

I'm confused about the FIFO error flag (FEIF) when I set up DMA for direct mode transfers. As I understand it, in direct mode the FIFO is disabled. But for some reason, if I enable the FE interrupt in the DMA_S...

Posted on August 08, 2013 at 23:58I'm configuring DMA almost identically and I'm having a similar issue. The documentation is really unclear. As far as I can tell, you're supposed to get a transfer complete interrupt when NDTR (BUFFERSIZE in your ...
