Buenas a todos, yo siempre he programado el pic en asm y la verdad que me parece muy fácil y asi he seguido hasta ahora pero bueno como la gente por aqui sabe programar en diversos lenguajes pues me puesto haber si me entero de algo con el C y me he instalado en el ordenador el PCWH_3.163 no se si será este en el que la gente programa pero bueno con este he empezado yo y bueno que sigo pensando que el asm es muchisimo mas fácil, aparte de todo esto, cacharreando anoche en el programa uno de los ejemplos que trae es el de simular un mouse con pic y bueno como este hilo va de eso pues aqui lo teneis, no se si servirá de algo, yo no me entero ni de lo que pone, pero bueno por si acaso os lo subo y ya está.

//// EX_MOUSE.C ////
//// ////
//// An example showing how to make a serial mouse using the CCS C ////
//// compiler. Your operating system / computer has to be able ////
//// to use a Microsoft Serial mouse or a Mouse Systems serial ////
//// mouse. ////
//// ////
//// Requires a special CPC cable connected to Port A. ////
//// ////
//// Wiring diagram for prototype board: ////
//// ----------------------------------------------------------- ////
//// 40 to 53 (Button 40 becomes left mouse button) ////
//// 41 to 54 (Button 41 becomes right mouse buttom) ////
//// 9 to 15 (Pot 9 becomes X movement) ////
//// 10 to 16 (Pot 10 becomes Y movement) ////
//// 7 to 12 (PC RxD connects to PIC C6 for Xmit of data) ////
//// 11 to 47 (PC DTR connects to PIC B0 for reset interrupt) ////
//// ////
//// This example will work with the PCB, PCM and PCH compilers. ////
