Resolved! STM32H743ZI I2C4 unexpected interruption
Hi,I recently need to use I2C with interrupt mode to lower my CPU usage.So I did this changes :I changed the function where I call my transmitstatic HAL_StatusTypeDef PGA309_Write_RawData(uint8_t REGISTER,uint8_t LSB_DATA,uint8_t MSB_DATA) { uint16_...
Resolved! Bug in documentation of timer outputs in STM32L496G Disco board?
A bit confused by STM32L496 DISCOVERY board.Documentation says Arduino compatible connector maps timer functions like following printscreen.But in CubeMX, the pins are very different, as can be seen on the following printscreens.E.g. Discovery board ...
LSI in Backup Domain on STM32H735.
Datasheet and Reference Manual have contradictions about the LSI Power.Information from Datasheet:The RTC is functional in VBAT mode and in all low-power modes when it is clocked by theLSE. When clocked by the LSI, the RTC is not functional in VBAT m...
Resolved! STM32F302R8 unable to use GPIO
Hi all, I am a new STM32 user migrating from Atmel/Microchip's SAMD line. I created my first project following along the tutorials here: https://www.youtube.com/watch?v=x_5rYfAyqq0&t=682s.It's a motor driver, with some other hardware shown outside of...
Resolved! TIM8 Input capture mode using firmware trigger?
I have a STM32G431 MCU board and TIM8 is triggered by an external input pin to perform a counter capture and initiate a DMA transfer for CH1. What I would like to also do on TIM8 is perform a counter capture based on a software trigger to CH3. Is thi...
STM32F091 Flash status SFR timing question during erare
I'm working on a bootloader which needs to erase and program the Flash. The erase seems to be 'working' but I have a suspicion that I'm not waiting long enough for the 'Busy' bit to go active after setting the 'Start' bit. The reference manual says I...
STM32L476RG detached Nucleo drawing 4.9mA even in Stop 2 Mode
The SetupI'm working on a prototype for a battery powered application on the STM32L476. I seem to have the code working, i.e. I put the MCU in Stop 2 Mode and wake it up after a sleep interval using the RTC. I've detached the base part of the Nucleo ...
How to setup SDMMC with the HSI48 clock?
Hi, i'm trying to configure the SDMMC device to be driven by the HSI48 clock, here is my configuration at the moment. Previously, i had configured the SDMMC with the PLLSAI clock and it worked at certain frequencies (38KHz.etc) but i've read in the s...
