/* 21_myBlink_v5 - Turns on an LED on and off for, repeatedly. Last Revised: 9/19/21 (v. 1.0) Based on mbed example. Modified by Dr. C. S. Tritt. This example code is in the public domain. */ // #include is a directive that "pastes" a file into your code. // Use this specific #include at the beginning of each mbed program. // mbed.h contains/points to the full definitions of our simple statements. #include "mbed.h" // Define the object board_LED to be a digital output connected to LED1, // which is the little green LED built into the Nucleo board. DigitalOut board_LED(LED1); const int WAIT_ON = 1400; // On time in seconds. const int WAIT_OFF = 600; // Off time in seconds. /* The "main" function defines your main program -- it executes as soon as you program the board. Functions can return (compute and give back) a value. The main function could return an integer error code, so it begins with int. Functions can also accept inputs. The main function cannot however, so its round parentheses are empty. */ int main() { // This curly brace marks the beginning of the main function. // while() will repeat a set of actions as long as the statement inside // its round parentheses is true. 1 is the definition of true, so // while(1) and while(true) repeat forever. while(true) { // This curly brace marks the start of the repeated actions. board_LED = 1; // Turn on LED by storing a 1 in board_LED. ThisThread::sleep_for(WAIT_ON); // Int value in mS. board_LED = 0; // Turn off LED by storing a 0 in board_LED. ThisThread::sleep_for(WAIT_OFF); // Int value in mS. } // end of repeated actions } // end of main function
