Resolved! USBPD EPR Source
Hi, I'm trying to implement USBPD EPR Source with DisplayPort Alt Mode on a STM32G071.I use the latest https://github.com/STMicroelectronics/stm32-mw-usbpd-core, which seems to support EPR, but I couldn't find any complete examples with a working EPR...
STM32F303CBT6 DAC not working with DMA
Dear all,I'm trying to generate a waveform using DAC OUT1.I configured pin PA4 as analog (works)I configured DAC1 without DMA and it worksI configured TIM6 and it works Then I configured DAC with DMA, configured DMA, but output never changes.Where ca...
Resolved! Does the IWDG window value cause a reset if the watchdog is refreshed too often on STM32G473?
I’m working with an STM32G473QETx.Does the IWDG window value cause the MCU to reset if the watchdog is refreshed too often (i.e., refreshed too early)?if I set the IWDG window value to something smaller (e.g., 1600), will the MCU reset if I refresh t...
PCB layout for oscillator - separated GND plane confusion
I am designing a 4 layer PCB which uses an STM32L433 and working on the layout for the LSE and HSE crystals. I referred to the application note AN2867 for guidance, but I am confused by the isolated ground plane underneath the crystals as shown in Fi...

Resolved! RM0456: 33.4.8 Extended calibration mode: Missing reset of ADC_CR_ADCALLIN bit?
Hello, ADC_CR_ADCALLIN is described as "rw" . The procedure given in RM0456: 33.4.8 Extended calibration mode does not explicit recommend to reset ADC_CR_ADCALLIN after the procedure. I think it is helpfull to add in RM0456.
