Generador simple de Onda cuadrada CCS
/////////////////////////////////////////////////////////////////////////
//// ////
//// This program displays a message over the RS-232 and waits for ////
//// any keypress to continue. The program will then begin a 1khz ////
//// square wave over I/O pin B4. ////
//// ////
//// Comment out the printf's and getc to eliminate the RS232 and ////
//// just output a square wave. ////
//// ////
//// Change both delay_us to delay_ms to make the frequency 1 hz. ////
//// This will be more visable on a LED. ////
//// ////
//// ////
//// Change the device, clock and RS232 pins for your hardware if ////
//// needed. ////
