H743 PB4 defaults to a high level issue.
When Pb4 is reset, it is at a high level. Can't this be configured in the hardware? It's too disgusting. The PCB has been designed and encountered this pit.

Do FSK or PSK using HRTIM on STM32G474RE
Hello everyone, I'm trying to do FSK and PSK modulation using HRTIM in STM32G474RE but I have what I want when I use Oscillo to display. For example, '1' = 45 kHz and '0' = 55 kHz. I want to transmit the message "1010" where each bit is 10µs long (F...
STM32H7 FMC and 16bits device
Hello,I'm kind of newbie in the STM32 world, I'm more used with another brand of 32bits microcontroller that also have a "parrallel port" for interfacing external ram device.My concern is about the FMC on the STM32H7.I want to read/write a 16bits dev...
