Trouble with Arduino - "Please select a port before upload"

@Chris_Woods

how often does Loop() get called? Is it on a frequency, or is it basically “while (true) { Loop(); }”?

Roughly 30 times per second, but that is not enforced… so it is best practice to use timers for anything that needs to happen on a schedule.

@move38justin

void loop() {
  // this happens over and over again 
  // the rate can be variable, but it will happen at 
  // a maximum the refresh rate of the display (~66Hz) 
}

also, i’m curious to know what functions in stdlib you are looking to use. It is possible that some of them should be part of our library.
