So i have spent some time programming with the ArdupilotMega + Shield combo and i just realized that my Accelerometer does not read all 3 axis. Using the APM_ADC test code, channel 3 always posts a steady 1550-1552 reading. Im not sure what is going one.
Although this is not posted anywhere this is what i have assumed based on all the code i have seen for the APM shield.
Gyros = channels 0,1,2
Accel = channels 3,4,5
Pressure = channel 6?
Is this correct? Channel 6 also produces a steady almost unchanging signal.
Or is my shield defective?
