Hola gente!:
Tengo un problema con los defines en 2 ejercicios que vienen con el compilador PCW compiler version 3.34.
Resulta que vienen dos ejercicios con LCD que no puedo compilar porque me da un error en la libreria LCD.C
Si alguien tiene el mismo compilador que yo se daran cuenta a que me refiero.Los archivos son Ex_lcdkb y EX_lcdth.
Cuando intento compilarlos me da un error de "undefined identifier set_tris_d en la lireria LCD.C.
Como no puedo adjuntar los 3 archivos te los copio aqui:Por ejemplo detallo el
archivo EX_lcdth.c:
/////////////////////////////////////////////////////////////////////////
//// EX_LCDTH.C ////
//// ////
//// This example demonstartes the use of the DS1621 chip. The ////
//// example reads the temperature and then sends it over RS232 and ////
//// to a LCD. ////
//// ////
//// Configure the CCS prototype card as follows: ////
//// Connect pin 32 to pin 40. ////
//// Make the following connections: ////
//// DS1621 pin Protoboard ////
//// 1 1 C0 (also use pull up resistor) ////
//// 2 2 C1 (also use pull up resistor) ////
//// 3 No connection ////
//// 4 27 Gnd ////
//// 5 27 Gnd ////
//// 6 27 Gnd ////
//// 7 27 Gnd ////
//// 8 28 +5V ////
//// See additional connections below. ////
//// ////
//// This example will work with the PCB, PCM and PCH compilers. ////
//// The following conditional compilation lines are used to ////
//// include a valid device for each compiler. Change the device, ////
//// clock and RS232 pins for your hardware if needed. ////

ME pueden dar una mano con esto??
