I use the arduino V1.0.3 compiler for windows and the last version of ArduPlane V3.1.1b.
The compilation process works well and I can make the hex file.
In order to toggle an output digital pin , Unfortunately, a compilation error occurs
"error: ‘digitalWrite’ was not declared in this scope".
I have gone through the internet and tried all the possible solutions but could not get any fruitful result.
Any ideas to solve this problem?
Thank you for your help.
