Resolved! STM32H7 consumes excessive current in custom board
Hi everyone! I designed the board shown in the attached picture. It’s built around an STM32H745 microcontroller, along with crystal oscillators, a DAC, an EEPROM, and an NE555 that generates a reset signal when a button is pressed long enough. Afte...
Resolved! FMC SDRAM design recommendations (STM32F446)
Hello,I am designing a board with a STM32F446 connected to an IS42S16160H SDRAM through the FMC interface.Could you please provide ST’s official recommendations regarding the use of series resistors on FMC lines?Typical values (22–33 Ω)?Any ST guidel...

CAN communication only working when the reciever is reset?
The goal of my project is to turn on an LED on the recieving side through CAN. Both my reciever and transmitter have the transciever circuit. Both are Nucleo boards, TX: F303RE, RX: F446RE. The data i am sending through is 16-bit, but as long as my r...
STM32H7S3L8 USB core reset timeout
Hey, we have purchased the Nucleo board H7S3L8-B02. We always run in a timeout during USB core reset. This problem seems quite popular with multiple forum posts. However we still didn't manage to get it to run. I will give a set by step explanation o...
To read write data into Flash W25Q16JV with STM32L452CE using SPI2 with CS pin PB12
I am trying to read ID and to write and read the data from the flash W25Q16JV with SPI2 of stm32L452CE connection, I am not even getting the ID from flash but SPI tx rx is getting HAL_OK. This wiring is working other code and providing unique ID from...

Resolved! Input timer setup halves period after 1st overflow and then remains in that state
Hi there, Ive gone around in circles for hours on this. I'm just trying to read a frequency, around 150Hz typ. using the 32 bit timers, for now just TIM2, 4 channel but behaviour same on all channels. Using 16MHz clock the timer overflow happens arou...
