C5402 DSK asm code for codec - Doreen Yeo Lee Guek - Nov 14 9:10:00 2000
|
Good day. 1)Just like to find out whether anyone try to hand code in assembly for C5402 DSK codec example? examples in DSK are C coded and clueless about the memory mapping, interrupt setting etc. 2) Tried to implement asm code for codec... setup McBSP1 and DMA ch2(receive) & ch3(transmit) for codec.. DMA ch2 interrupt branch to a FIR routine...the interrup service routine is working fine but the codec is enabled even when DSP is halted! then the DSK will crash on me with error as follows:- Cc-app This program has performed an illegal operation and will be shut down. If problem persists, contact the program vendor. have you encounter this problem before?
