Hi, I posted a message a few weeks ago about this problem but I am still having trouble with a sampling routine being interrupted causing it to miss samples. My setup is: programmed in CCS, using the onboard codec to sample from the mic port, using RTDX to transfer data between target and host, no interrupt routines setup. The code runs fine but during the sampling loop there is a problem because it misses a whole load of samples. This only happens if I check the RTDX box in CCS (which I need to use), but supposidly RTDX transfers data in the idle process.... (I do not have to reload code between checking the RTDX box so there is no change on the target). Does anyone have any clue what I can do next to help find the problem? I have tried disabling all interrupts before the critical section, then enabling them again after which makes no difference! Cheers, Andrew |
