M93C76RT self-timed programming cycle
Hi there,From testing it's quite jarring to me to discover that after every 16bit write u need to wait ~5ms before the EEPROM will accept after write. After a more detail reading of the manual I found that after SPI write cmd the EEPROM will trigger ...
can't find CanMsgTypedef in the stm32l4xx_hal_can.h
I am trying to init the can tx and rx, what i see from the tutorial there should be a CanMsgTypedef in the stm32 driver for the specific mcu. now I am using the stm32l4xx_hal_can.h since I am using the stm32l4a6zg mcu that comes with the nucluos 144 ...
Resolved! I am using an STM32H743 user board with STMCubeIDE. I want to use the internal RTC calendar with the internal clock (LSI). Q: first power on clock start 17:20:00 then time is going. For example, when time is 17:20:50 suddenly I power off the

Resolved! STM32H743 RTC freeze when power is off
The RTC program is tested with LSE
i am using stm32f373, i want to use USART2 to communicate through modscan kindly help me in With the configration of usart2.

HAL_Delay not affecting frequency of a Blinking Light
I am new to STM32, and I am using a STM32L152c discovery board to run a sample blinking light program. I am using HAL_Delay to control the frequency of the blinking light. However, the frequency does not change when I change the argument to HAL_Delay...
Generating HDMl signals from an stm32f0 is possible?
7 years ago I made a personal project, which generates video via vga, now I would like to do it via HDMl, I have only found with fpga, but the code is not clear to me, I suppose it is vhl, or vhdl, but I would like to do it with stm32f0,will anyone h...
Resolved! STM32L031 - LSEDRV "lock" does not work
I've just tried on an 'L031 - after writing LSEDRV to 0b00 (using debugger), I can rewrite it freely to any other value, and the oscillator's behaviour follows the value written.Can ST please comment.JW
Reset state of certain GPIOs in STM32G431x has unknown behaviour(s)
Hi everyone,I am currently migrating from STM32F303x to STM32G431x microcontroller (48-pin package) and started testing the GPIOs in reset state, without any firmware on-board. Also, there are no external HW circuitries connected to the pins (I meant...
