| So basically your entire complaint is that you don't have 50% duty cycle.
Possibly I'm not describing my issue very well. I can get 50% duty cycle no problem, and in fact it is the one exceptional ... |

| Neither your text version or your picture show P1A=P1B. P1B is off when P1A is ON, less the deadband times.
I agree it's not P1A=P1B, but if you look at the original post I suggested P1A=!P1B. (i ... |

| Hi Ttelmah,
set_pwm1_duty(75L); I appreciate the syntax correction, but that still didn't resolve the issue. I'm still getting P1A=!P1B instead of what's described on page 198 of the datasheet. ... |

| Hi All,
I am trying to setup a half bridge driver using a PIC16F1933. According to the datasheet (page 198) I should see this (ignore dead-band for now): P1A: ____|--|___ P1B: |--|_____| ... |

| The AC162049 Instruction Sheet says the USB-powered programmer
(ICD2 and presumably ICD-U40, etc.) must have an external power supply. Do you have one attached ? I do have external power applie ... |

| Hi All,
I'm having an issue programming a PIC18F4431. I believe I have the circuit setup correctly. Originally, I was using a Microchip AC162049 target board (slightly modified, with the LED rem ... |
