| CCS Bug !?!?!? |

Plz lets consider the following simple code:
| Code: |
#include <16F877A.h>
#device adc=8
#FUSES NOWDT
#FUSES XT
#FUSES PUT
#FUSES NOPROTECT
#FUSES NODEBUG
#FUSES BROWNOUT
#FUSES NOLVP
#FUSES NOCPD
#FUSES NOWRT
#use delay(clock=4000000)
#use rs232(baud=1200,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8)
void main()
{
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(FALSE);
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
setup_timer_1(T1_INTERNAL|T1_DIV_BY_1);
setup_timer_2(T2_DIV_BY_4,249,1);
setup_ccp1(CCP_CAPTURE_RE);
set_pwm2_duty(124);
setup_ccp2(CCP_PWM);
setup_comparator(NC_NC_NC_NC);
setup_vref(FALSE);
while(1);
}
|
This code will generate a 1Khz PWM on CCP2.
When compiled using CCS v: 4.017 -> Nothing  
When compiled using CCS v: 4.013 -> PWM 
Any thoughts?

Yes. Use 3.249.... 
The 4.xxx compilers, seems now to just about be starting to work. I have compiled three test programs, that previously would not work properly with earlier V4 compiler versions, and with 4.023, and they are at last producing working code. There are still problems with a lot of the 'new' stuff, but the compiler looks to at last have just about reached a possible 'beta' status in my mind. The versions before this, are not useable compilers, unless you are very lucky (look at the posts about this). 3.249, is a reasonably stable working compiler, and unless you 'need' one of the new features, would be the preferred choice.
Best Wishes |
