Hi, I am building a program which captures data from the PCM3003 audio card, by means of HWIs, and sends it to a PC, via JTAG, when 512 samples are available. I am using the TMSC6711 DSP. Do the HWI interfere with the RTDX? When I try to use interrupt- driven RTDX

Hi, Im attempting to connect a GUI (running on the host computer) to the 6711DSK. The idea is that I have developed a small library of real-time audio effects using the PCM3003 Daughter card, and I wish to use a simple GUI to allow the user to control the effects rather than having to reload each effect algorithm and using the DIP switches to alter the parameters. Basically, it will be somethin...
