Hello, Is there a way to modify the SPORT talkthru example that comes with the EZLAB board to just do sound out? At the moment I have a MAFE expansion card set up on SPORT0, and can get the code modified to the point where it will play a canned tone that I store in memory as an array. My problems are as follows: 1. I'd like it to play the vales in the array, and then stop. But I can't seem to do that without disabling the SEN bit. If I leave it as-is, the tone will play continuously, until I reset the board. 2. I would like to remove all the code for the receiver portion of the code, but any time i try to set up just a serial port transmit, it won't play anything. 3. i want to be able to generate tones on the fly, and not simply read an array out in data memory. However any time I try to send merely a string on amplitudes to the tx_ buffer, again, nothing happens. The values appear in the buffer, but no sound comes out. I've read through the entire MAFE user's manual, as well as the manual for the card, and anything I could find about SPORT transfers. I think I have the registers set up properly for initializing both the expansion card, as well as the SPORT. Any suggestions where I might be going wrong? Thanks in advance :) Tom Hanley |
