| PIC16F18446 PWM problem [Solved] |

Hello,
I use 16F18446 but i can't run pwm1 and pwm2 output. I try close pwm mode and try pin_c2 pin general output pin type output_toggle(pin_c2) command. But it's not change high-low. If i try pin_b6 pin correct.
My code see below.
| Code: |
#include <16F18446.h>
#fuses NOEXTOSC,RSTOSC_HFINTRC_32MHZ,NOMCLR,NOLVP,NOCLKOUT,BORV27
#device ADC=12
#use delay(internal=32000000)
#pin_select CCP1OUT= PIN_C2
#pin_select CCP2OUT= PIN_C3
#INT_TIMER1
void TIMER1_isr(void)
{
set_pwm1_duty(500);
set_pwm2_duty(255);
set_timer1(50000);
void main()
{
SETUP_ADC(ADC_LEGACY_MODE | ADC_CLOCK_DIV_32);
setup_adc_ports(sAN2 | sAN4 | sAN5);
setup_oscillator(OSC_HFINTRC_32MHZ | OSC_HFINTRC_ENABLED);
setup_timer_2(T2_DIV_BY_16,255,1); //512 us overflow, 512 us interrupt
setup_ccp1(CCP_PWM);
setup_ccp2(CCP_PWM);
setup_timer_1(T1_INTERNAL | T1_DIV_BY_4);
enable_interrupts(INT_TIMER1);
enable_interrupts(GLOBAL);
while(TRUE)
{
RESTART_WDT();
}

hello,
I found self mistake. I did change timer2 setup command.
| Code: | | setup_timer_2(T2_CLK_INTERNAL | T2_DIV_BY_16,255,1); |
its work.
