I'm just getting started in the micro controller world. I now have my msp430-gcc and msp430-gdb working. I can run the little led-flashing programs great.
What I want to build is a little card that will output three different sub-audible tones, 100hz, 123hz, and another similar one. I would like three pins as input to select which tone to output, then have the appropriate tone appear on the single output pin. I'll be putting this into an older kenwood vhf 2meter ham radio. So I am trying to match the configuration already indicated by the radio's wiring diagram. I have seen some examples of PIC programming for doing telephone DTMF touch tones. I don't need to be that fancy. These are only single tones, and much lower frequencies. I think maybe I want to use timerA to generate my tones? I'm looking for any advice on example code I can use, or general direction I should follow. Thanks all. -- Chris Howard YipYap.Com ch...@yipyap.com Estes Park, Colorado USA current Estes Park weather -- http://www.yipyap.com/wscurrent.html
