Now I need 3 PWM-channels with 1kHz duty and 10 i/o-channels. Any other chip? Can we assume you mean 1kHz frequency? Mike PS Try microchip website for chips with more than 2 PWMs. Sorry ... |

| I have used 2 PWM-channels earlier but cant figure how to use three PWM:s simultaneously?
This is what I have used: setup_timer_0(T0_EXT_H_TO_L|T0_DIV_1); setup_timer_1(T1_EXTERNAL|T1_DIV_BY_1) ... |

| Could you give me example how to do adc readings in sleep mode with 18F4523? I just don't understand what are correct adc clock values with 4Mhz oscillator if I use just read_adc()? Last two bits in ... | |

Forum: General CCS C Discussion Posted: Wed Jan 05, 2011 7:50 am Subject: 18F4523 PEIE and ADIF registers |
| I have used following code for 18F452 to read adc in sleep mode:
#bit PEIE=0xFF2.6 #bit ADIF=0xF9E.6 #use delay(clock=4000000,RESTART_WDT) long int true_adc (void) { lon ... |
