2008-02-21 Thread Coalton Bennett
I have been trying to get the ADC to work with the MDA300CA, and it seems as though something is being sampled, but the values that I am getting are wrong. We are sampling a 1.5V DC battery. We chose the 1.5V DC battery to test our application with because it has a constant value, so in the

Greetings All, I have a question regarding the 51 Connector MICAz Expansion Connector. I already have a sensor built which outputs an analog AC voltage measurement with a "maximum(peak)" amplitude of about 2 volts AC. The amplitudes are not strictly 2 volts in amplitude. The amplitude

This should be quite do-able...if you don't have a map, I have a list of the 51 pinouts at: http://www.etantdonnes.com/Motes/ATMEGApins.txt Assuming that the (-) wire on your sensor is actually battery ground, or that it can be connected to such, you need to connect the other (+) wire to one o
