Cooper (who also happened * to be Brett's controls professor) is an excellent reference: * * http://www.controlguru.com/ */ /** * Includes */ #include "mbed.h" Serial host (USBTX, USBRX); DigitalIn btn(D2); DigitalOut led(LED1); /** * Proportional-integral-derivative controller. */ int main() { int i = 0; host.baud (38400); while (true) { if (!btn) { /// show msg in serial host.printf ("Hello, count = %d \r\n", i); i++; } else host.printf ("Wait... \r\n"); led = btn; wait(0.2f); } }
