 Forum: General CCS C Discussion Posted: Wed May 31, 2023 11:37 am Subject: dsPIC33 HSPWM, phase-shift PG2 relative to PG1 not working |
| Correct, this is only running for the slave.
The AFPLLO is producing 0.5Ghz: void AFPLLO_settings(void) { // can get AFVCO to 1GHz and AFPLLO to 500MHz // Configure APLL pr ... |

| Hi all,
I'm using the dsPIC33CH512MP508, a dsPIC with a master and slave core. Currently using PCWHD 5.093. The HSPWM configuration settings are based on the Microchip code example on github: ht ... |

| Thank you for the reply Ttelmah. Unfortunately, set_hspwm_duty only controls the duty cycle. After looking under CCS index I came across "set_hspwm_period", which solved my issue. I'm now ab ... | |

| Hi all,
I'm using the dsPIC33CH512MP508, a dual core PIC with a master and slave core. Currently using PCWHD 5.093. I'm able to generate a push-pull signal on PWM1H and PWM1L, and adjust the dut ... |

| You are correct! I have replaced the crystal with a 20MHz version (measured at 19.68 MHz), and the slave led is flashing and Master UART outputting the ADC reading from the MSI.
I am slightly confu ... |

| The crystal has 64MHz engraved on it, the timing was all wrong and UART was printing garbage. So I probed the crystal output and that was the frequency coming out of it (21.336Mhz), once I entered tha ... | |

| Hi,
I am using the dsPIC33CH512MP508 with the example code "ex_ch_master.c" and "ex_ch_slave.c" files, slightly modified to match the clock and master/slave led pins. I am using ... |
