I am trying to run the most simple example of PWM using a PIC18F4550, XC8 compiler and the libraries plib/timers.h and plib/pwm.h
My code is the next:
#include <xc.h> #include <plib/timers.h> #include <plib/pwm.h> //CONFIGURATION BITS... #pragma config PLLDIV = 5, CPUDIV = OSC1_PLL2, USBDIV = 2 #pragma config FOSC = HSPLL_HS, FCMEN = OFF, IESO = OFF #pragma config PWRT = OFF, BOR = OFF, VREGEN = OFF #pragma config WDT = OFF, WDTPS = 32768 #pragma config MCLRE = ON, LPT1OSC = OFF, PBADEN = OFF #pragma config STVREN = ON, LVP = OFF, ICPRT = OFF, XINST = OFF #define _XTAL_FREQ 48000000 void main(){ TRISCbits.TRISC2 = 0; unsigned char prescaler = T2_PS_1_16; OpenTimer2(prescaler); OpenPWM1(0x95); while(1){ SetDCPWM1(300); } } And the diagram of my PIC is:
But I get an error message when trying to compile:
C:\Program Files (x86)\Microchip\xc8\v1.40\include\pic18f4550.h:4426: error: (1098) conflicting declarations for variable "_TRISCbits" (C:\Program Files (x86)\Microchip\xc8\v1.40\include\pic18f4550.h:3829) (908) exit status = 1 nbproject/Makefile-default.mk:125: recipe for target 'dist/default/production/PWM_code.X.production.hex' failed make[2]: Leaving directory 'C:/Users/Delfin/Pictures/PIC18F4550 Basics/PWM_code.X' nbproject/Makefile-default.mk:84: recipe for target '.build-conf' failed make[1]: Leaving directory 'C:/Users/Delfin/Pictures/PIC18F4550 Basics/PWM_code.X' make[2]: *** [dist/default/production/PWM_code.X.production.hex] Error 1 make[1]: *** [.build-conf] Error 2 make: *** [.build-impl] Error 2 nbproject/Makefile-impl.mk:39: recipe for target '.build-impl' failed BUILD FAILED (exit value 2, total time: 1s) I have already downloaded and installed the periperial libraries from here: http://www.microchip.com/mymicrochip/filehandler.aspx?ddocname=en574973 and also linked them in my code as I show in the following picture:
So, why is not compiling? When I comment the line:
OpenPWM1(0x95); works fine. I would appreciate any suggestions. Thanks
