Description of problem

There appear to be some special analog input ports that are not defined in the PlatformIO environment, but are defined in the Adafruit boards for the Arduino IDE. I am specifically using the Adafruit Feather M0 Bluefruit LE and the desired pin is analog pin 7 which is defined in the Arduino IDE as A7.

The Adafruit boards I installed were from https://adafruit.github.io/arduino-board-index/package_adafruit_index.json

Steps to Reproduce

1. Attempt to access analog pin A7. For instance, analogRead(A7);

   Actual Results

src/main.cpp:69:16: error: 'A7' was not declared in this scope
[ ERROR ] Took 6.95 seconds

Expected Results

[SUCCESS] Took 7.87 seconds

framework = arduino
board = adafruit_feather_m0_usb

Source file to reproduce issue:

void setup() {
  // put your setup code here, to run once:
  analogRead(A7);
}

void loop() {
  // put your main code here, to run repeatedly:

}

Hi @bcr ! Fixed in development branch.

Seems to be working great, thank you!

It was working fine but now I cannot use Analog 6 or 7 anymore

void setup() {
  // put your setup code here, to run once:
  analogRead(A7);
}

void loop() {
  // put your main code here, to run repeatedly:

}

it gives : error: 'A7' was not declared in this scope
