I’m trying to go through a few books to learn Arduino programming and really like PlatformIO IDE but I keep running into issues with code that won’t work in PlatformIO but will work in the regular Arduino IDE. It’s a simple program that flashes the built in LED, when I build it i get an “error: ‘flash’ was not declared in this scope”.
Here’s the code:
// sketch 4-02
int ledPin = 13;
int delayPeriod = 250;
void flash(int numFlashes, int d)
for (int i = 0; i < numFlashes; i ++)
Am I missing something super obvious? Thanks in advance for any help!
