I cleaned out files to gain additional memory on Mac Catalina OS 10.15.7 .
Now, when verifying, IDE 2.3.2 throws errors on Arduino Functions, Variables and Structure Elements.
I reinstalled the IDE with same result. I installed IDE 1.8.19 with same result.
I would appreciate help in solving this problem. Tks.
Example Using Builtin Sketch ‘Blink’
/*
[https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink]
*/
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
