 Forum: General CCS C Discussion Posted: Mon Jan 08, 2024 3:20 pm Subject: PIC18F23k22 UART2 pins sharing with programmer |
| I need two UARTS to connect to a PC and another serial device.
The PIC18F23k22 choosen supports two UARTS. Unfortunately the 2nd UART shares the pins with the programming interface. (PGC and PGD) ... |

| Many thanks for your answers!
I didn´t know that I can set the duty to 0% or 50% to change the output behaviour of the pwm. Feeding back the output to a timer input is a nice idea. This gives ... |

| Hi,
I need to pulse a red laser diode with a fixed number of 40 KHz, 50 % duty pulses. Clock is a 16 MHz Crystal. The modulation input of the laser driver is connected to the CCP1 pin. Also I can ... |

Thank you for the explanation. I didn´t know that the #bit directive uses bit set, test and clear instead of byte operations. I will use this in the future. @asmboy I have found thi ... |

| @Ttelmah
finally I found the problem. It was the bit setting of the PIR1 register. I do not really understand the reason. Can anyone explain this? Why is if( (PIR1 & 0x02) == 0x02 ) not ... |

| Hi,
I am using PIC12F1822 to generate a sine wave via pwm. The code was written and tested on silicium mask level 8. But now I got mask level 9 and the code does not work anymore. After some t ... |
