Arduino NANO and Firmata - Analog Pin Numbers

kli — Sat, 18 Nov 2017 17:10:10 +0000

Dear community, I need to address all pins (digital and analog) of my Arduino NANO via Firmata. My Arduino Sketch is one for multiple circuits (educational purpose) and I changed all the Axxx-pins in the .pde-Sketch (see below) according to the pin map A0=14, A1=15 etc. but I got an error message for pin 18 (out of range) and I don't know how to address A6 and A7 because there are no digital numbers in the pin map for them. I tried to just use the numbers without A (A2=2 ...) but this doesn't work for me because there are conflicts with the digital pins and the use of same pin numbers. Can anyone help me how to address ALL pins by numbers? And: do I have to change the StandardFirmata to use it for the NANO and to use all the pins? Thanks in advance. KLI
