Hello, I'm actually facing a problem : I would like to transmit frames of variable lengths made of 8 bit elements, using both McBSP and DMA. I don't know exactly how to configure DMA and McBSP. I use the McBSP event to synchronize DMA transfer but I don't know if I have to configure McBSP in Dual-Phase (8/8) or Single Phase (8 but I suppose there will be a problem with th DMA, won't it?). What do I set for the DMCTR (size of the frame in 8 bits or in 16 bits?) I'm quite new in DSP programming and have only an eval version of Code Composer Studio (which don't permit simulation of DMA and McBSP), so I can't test solutions for the moment (I'm waiting for complete version of the tool, but I have to go through my quite slow society administration...) Thanks for your answers |
