//This is known as a “header file” //In short, this copies and pastes the text file //mbed.h into this code #include "mbed.h" #define kRED 1 #define kYELLOW 2 #define kGREEN 4 BusOut binaryOutput(D7, D6, D5); //Outputs as an integer unsigned int state = 0; void toggleYellow() { if (state == 0) { binaryOutput = kYELLOW; state = 1; } else { binaryOutput = 0; state = 0; } } //The main function - all executable C / C++ //applications have a main function. This is //out entry point in the software Ticker T; int main() { binaryOutput = 0; // ALL the code is contained in a // “while loop" // THIS IS NOT AN IDEAL SOLUTION. HOWEVER IT IS SIMPLE while(1) { //The code between the { curly braces } //is the code that is repeated //STATE 1 (R) binaryOutput = kRED; wait(4.0); //STATE 2 (RA) binaryOutput = kRED + kYELLOW; wait(4.0); //STATE 3 (G) binaryOutput = kGREEN; wait(4.0); //STATE 4 (Flashing A) T.attach(toggleYellow, 0.25); wait(4.0); T.detach(); } }
