Hello,

I'm using the ez430-rf2500, I need to manage 4 ADC at the same time. I tried to call them as diferent functions, but the ADC returns  the same value all the time.

    You can’t read 2 or more ADC channels simultaneous in this MCU, you have to select and read the channels one by one.

    As Leo said, the ADC10 can only sample one input at a time. If your functions require the ADC results without any ‘handshake’ between them, a possible solution is to run the ADC independently, scanning all inputs over and over again and writing the results into a memory array. So the functions can just pick the latest result from the array whenever they need it.
