Hello All,
I am trying to read a resistive type sensor connected to two PICs, a 16F88 and a 16F685. When either PIC is connected to the sensor by itself, it works fine. But when both are connected, neither one reads correctly. The sensor has a range of 0 to 90 Ohms, and I'm using a 100 Ohm resistor between the input pin and Vcc on each PIC.
I'm sure you're asking yourselves why I don't just have one PIC perform both functions... well it's a long, ugly story. Let's just say I'm stuck with this setup and I have to make it work (or not). I'm using the default settings for ADCIN.
Any tips, hints, enlightened insights would be much appreciated. I really need to put this project (and myself) to bed.
Thanks in advance,
Pete K.
P.S. I have a hunch that the problem lies more in the circuit than in the software. Then again, the last time I had a hunch I lost a hundred bucks at the Blackjack table in Vegas!
