Hi there,

I'm attempting to utilize all 16 analog inputs of my Arduino Mega to receive pressure sensor data into the Arduino Mega PD patch- and I'm getting mixed results.

I have Arduino 0018, fimata 2.1beta7, but I still am not getting clean data. Nothing from inputs 8-16 whatsoever. I was successful at some point getting accurate data on pins 0-7, but now I'm just getting noise, or I'm getting only a reading of 1 while the sensor is activated, and just noise when it is not.

Any advice would be greatly appreciated. : )

Thanks so much.

HCS can tell you for sure, but it sounds like the firmata doesn't support the mega? Check your wiring, make sure nothing is shorted. You could try debugging in a serial console, too.

Here is what you need

there is a sip file there you can download with a ready made patch for 16 analog outputs from the arduino mega
