| error after compiler update |
 Posted: Fri Apr 15, 2016 2:11 pm |

I was using ver 4.141 and could compile without errors.
I updated to ver 5.057 and now get the following:
*** Error 99 "main.c" Line 45(5,68): Option invalid Software PWM frequency is not achievable with Timer 2
*** Error 99 "main.c" Line 46(5,68): Option invalid Timer2 already being used for another PWM
I can deal with the first error by changing the frequency, it's the second one I'm not sure how to deal with.

It compiles if I add FORCE_HW to each #use pwm() statement, as shown below in bold:
| Quote: | #include "18F67J93.h"
#ignore_warnings 202,240
#DEVICE ADC=10
#device *=16
#fuses WDT,NOPROTECT,INTRCPLL_IO,NODEBUG,CCP2C1
#use fast_io(all)
#use delay(clock=8000000)
#use rs232(uart1, baud=9600, RESTART_WDT, PARITY=N, BITS =8, STOP=1,stream=PC)
#use spi(FORCE_HW, BITS=8, baud=9600, MODE=0)
#USE PWM(PWM2, OUTPUT=PIN_C1, FREQUENCY=10kHz, DUTY=0, FORCE_HW)//unlatch C1 P2A
#USE PWM(PWM1,OUTPUT=PIN_C2,FREQUENCY=10kHz,DUTY=0, FORCE_HW)//unlatch C2 P1A
#use fast_io(ALL)
#include <stdio.h>
#include <stdlib.h> |
Compiler output (with vs. 5.057):

| Thank you so much for the FORCE_HW. That did the trick. |
