First, my setup. I've set up a circuit which uses 20 pins on an Arduino Leonardo. 10 analog (A0, A1, A2, A3, A4, A5, D12, D10, D9, D8), 10 digital (D0, D1, D2, D3, D4, D5, D6, D7, D11, D13). I've upgraded Firmata to version 2.3.2 to access the new analog pins. I can successfully hit all the pins from Firmata (via openFrameworks) except pin D1. Within the Arduino IDE I can hit every pin successfully.
A question about Firmata. Should I avoid using the TX/RX pins entirely? If I activate the pin D1, D0 activates and D1 does not. At first I thought it may be a circuit issue, but the Arduino script can set the D1 to HIGH without affecting D0. This leads me to suspect it's an issue with the way I'm accessing it through Firmata.
I've also tried attaching to the digital pins in the ICSP header D14, D15, D16, D17, without luck.
I'm hoping someone has some insight to point me in the right direction. Thanks.
