PinNumber vs PinName
Posted: Sat May 02, 2020 4:33 pm
Here is an example using both methods:
If you want to use a pin name in a function that takes a digital pin use pinNametoDigitalPin().
If you want to use a digital pin on a function that takes a pin name, use digitalPinToPinName().
Code: Select all
void setup() {
pinMode(PC13, OUTPUT);
pinMode(pinNametoDigitalPin(PC_13), OUTPUT);
}
void loop() {
digitalWrite(PC13, 0);
digitalWrite(PC13, 1);
digitalWrite(pinNametoDigitalPin(PC_13), 0);
digitalWrite(pinNametoDigitalPin(PC_13), 1);
digitalWriteFast(PC_13, 0);
digitalWriteFast(PC_13, 1);
digitalWriteFast(digitalPinToPinName(PC13), 0);
digitalWriteFast(digitalPinToPinName(PC13), 1);
}If you want to use a digital pin on a function that takes a pin name, use digitalPinToPinName().
