Resolved! 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.

Hi Guys,I am recently facing a very rare problem on stm32 nucleo h755zi- q i am working with ltc6804ic for a BMS and am facing the following issue:Whenever i upload the code on the stm32 it crashes, and says no debung info available etc, after this i...
Hello! I am using Zync SOC with STM 32 G4 series. I am targeting 1Mbps baud rate using CAN protocol. I am able to achieve 1Mbps using external loopback on STM. Can someone help me out with bit timing and prescaler values for STM 32 and Zync SOC
Hi ST Community,I’m working on a CAN FD project using the STM32H753VIT6 and facing a limitation with data phase bitrate while using Bit Rate Switching (BRS).My Setup:Controller: STM32H753VIT6FDCAN clock source: PLL1QPLL1Q output: 40 MHzFrame format: ...
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...
1. Product DescriptionThe product is an automotive remote controller that uses STM32L412RB as an MCU.The product uses a rechargeable battery and has a power on/off function for storage and delivery. 2. ProblemSome products (0.2%) stop operating due t...
I want to use LPTIM1 of the STM32G0x1 to wake up the MCU, if it's not already awake, and start a DMA multichannel single conversion. I think I know how to do the DMA/ADC part after getting the ADC_MultiChannelSingleConversion example running; I'll th...
Hi,I have two identical flight controllers from BetaFPV:https://betafpv.com/products/f405-4s-20a-toothpick-brushless-flight-controller-v5-blheli_s-icm42688?_pos=11&_sid=55080f3df&_ss=rboth using an STM32F405 MCU. I noticed that the unique device IDs ...
Hi, ı am trying to send some buffered data via SPI but it doesnt work. PA5-6-7 are automatically set by SPI and I also enabled PB6 for CS. Normally my algorithm needs to:1) Send 3 HF pulses to low and start interleaved ADC simultaneously.2) Take 1400...
Hi all,I'm working on the STM32U5G9J-DK development board and trying to enable USBX-based MSC (Mass Storage Class) device functionality.My actual product is a battery-powered device, so USB Power Delivery (PD) is not an option. However, it's critical...
