| Pwm no way CCP for Timer0 |

Hello!
Ttelmah, I wanted the 3 pwm to read the values of the matrix understood without being automatic in the for loop
God bless you Thank you for your help !
| Code: |
#include <16F628A.h>
#FUSES NOWDT, HS, NOMCLR
#use delay(clock=4000000)
#int_timer0
void pwm_duty(int pwm0, int pwm1, int pwm2){
int cont;
if(cont>15)
cont=0;
else
cont++;
if(cont>0&&cont<pwm0)
output_high(PIN_B0);
else
output_low(PIN_B0);
if(cont>0&&cont<pwm1)
output_high(PIN_B1);
else
output_low(PIN_B1);
if(cont>0&&cont<pwm2)
output_high(PIN_B2);
else
output_low(PIN_B2);
set_timer0(0);
}
void main(){
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
set_timer0(0);
enable_interrupts(INT_TIMER0);
enable_interrupts(GLOBAL);
while(true){
int r, g, b;
for(b=0;b<16;b++){
pwm_duty(16,0,b);
delay_ms(50);
}
for(r=16;r>1;r--){
pwm_duty(r,0,16);
delay_ms(50);
}
for(g=0;g<16;g++){
pwm_duty(0,g,16);
delay_ms(50);
}
for(b=16;b>1;b--){
pwm_duty(0,16,b);
delay_ms(50);
}
for(r=0;r<16;r++){
pwm_duty(r,16,0);
delay_ms(50);
}
for(g=16;g>1;g--){
pwm_duty(16,g,0);
delay_ms(50);
}
}
}
} |
Ttelmah you are a super saiyan help me to become a super sayiajin too

Where is the rest of the code?.
You have posted an 'excerpt', again with nothing setting up the PWM,
and without anything setting up the chip itself.
There is no command 'pwm_duty'. There is pwm_set_duty, when using a
stream with #use pwm, or set_pwmx_duty when using setup_ccp.
Look at the examples, and read the manual.
EX_PWM.C
The PWM, has to use timer2 on the chip you show (on most of the more
basic PIC's).
That chip also only has one PWM. |
