STM32F072 PWM One pulse
HelloNeed help, need to set PWM in a one pulse mode, so that at start timer there would be a low level output for a time equal to value of CCRx, after compare the output would be change to a high level and would remain so after overflow and stopping ...
Resolved! STM32H755 Dual Debug Startup Problem
Hi community,I have a problem that other people have also raised and I'd be grateful for help.I followed AN5361 and I watched this STM video on the same topic. First thing to mention is that the video and doc have different advice about whether the C...
Resolved! NUCLEO-H753ZI: Communication with PC
I'm trying to use my NUCLEO-H753ZI board to send some message to my PC using UART. I read from the data sheet that USART3 is connected to the ST-LINK for the Virtual COM Port (VCP), and USART3 can directly transmit messages to the PC. However, in the...
Resolved! Adjustable power outputs for Vddcore for STM32N6 using mosfet
In the schematic for STM32N6 Vddcore power rail (attached), voltages of 0.81V and 0.89V are output from the SMPS using resistor dividers. I understand how the output of 0.81V was achieved using the 56K and 160K resistors and formula from the SMPS dat...

Resolved! STM32U5 HSE Crystal
I'm currently at schematic stage designing a board based around the STM32U5G9ZJT6Q. The PCB will be produced and assembled by JLCPCB, so I had a look for a HSE crystal they have in stock and found this:https://jlcpcb.com/partdetail/YangxingTech-X3225...
HAL_SPI_Transmit() returns HAL_ERROR STM32H7R3V8H6
Hello, I'm running into an issue interfacing the STM32H7R3V8H6 with a MAX31856 where whenever I try to use any sort of SPI functionality, it returns HAL_Error. This issue surprises me because the code that I am using is identical to the code I used o...
Read Protection level 1
When I tried to enable read protection level 1 through STM32Cube Programmer(using ST link and J link), I was able to do so successfully. However, after enabling read protection, none of the peripherals worked properly—specifically, the push button an...
Resolved! STM32H7 GPIO control by both M4 and M7
Hello,I have a GPIO pin that is owned and used by the M4, i.e. Pin Context Assignment. But on power-up, I'd like the M7 to do some work with it, toggle the state, before it starts the M4. Is it possible for the M7 to programmatically take ownership...
