Hi,
I am thinking of doing a project that involves connecting a PIR sensor to a high performance DSP such as the TI C6713. I would like to take the analog output of the PIR and send it to the DSP for processing. From my past knowledge with the C6713 DSK, there are two analog inputs that can be plugged to mics only. Is there a way to connect the analog output of the PIR to the C6713 DSK so it can be digitized then processed.
One idea that occured to me is to use the GPIO but then I think the ADC must be done externally (right?)
Any suggestion?
