Hi, I have a C6711 DSP with CCS 2.2. My program uses interrupts to get data from the PCM3003 audio daughtercard and I wish to send data through RTDX in real-time. Following an earlier question, I was told that the HWI (from the daughtercard) could interfere with RTDX. I tried to use the polling implementation of RTDX and everything seems to go well... until the data output stops at some point (the program keeps running with no problem, only RTDX stops). Could this have anything to do with the polling implementation? I used the following method: After enabling the polling implementation (in rtdxpoll.h), I created a PRD function which posts the SWI that calls the function which polls data ( RTDX_poll() ). I could not find any suitable examples or application notes with my requirements. Am I doing the thing right? Can I use polling? If not, how do I use the interrupt version without interfering with the data I/O from the daughtercard? Thanks in advance for any help! Regards, Andre Leitao |
