Resolved! GPIO pins stuck in HIGH state
HiI am working on a project using LL libraries and STM32F407VET6 Board. (I have attached the main.c code here.) The code generated by the STMCube GUI configuration tool is causing issues with two GPIOA pins (Pin 6 and 7) stuck to HIGH whenever the co...
Resolved! STM32G474 HAL_TIM_Encoder_Start_DMA Question
Hello STM32 MCU Community,I was looking for clarification on the HAL_TIM_Encoder_Start_DMA function as I want to do a DMA transfer of an encoder's count register to a buffer. From the STM32G474 reference manual, I thought I would need to use another ...
What should be the HSE (bypass clock source) characteristics for STM32F7 to work fine?
Hello everyone,I have an STM32F765VI MCU. When I work with internal clock it works fine. But when I switch to an external TCXO, It does not work properly. The TCXO output is a 26MHz sine wave with 1.5V peak to peak.Does anyone know what may cause thi...
Resolved! Moving from HAL (working) to LL (issue), SPI always receive 255
Hello everyone,I am facing an issue during migration from HAL libraries to LL. I need to increase performance of my code and better understand STM peripherals.My MCU is STM32F746 on a custom board.CubeMX configuration for SPI1 is the same for HAL && ...
Resolved! Formula for calculating IWDG timeout for STM32F0 series
Which document to refer to find formula for calculating IWDG timeout for STM32F0 series(STM32F0C038 to be more specific)? I have found formulae for other parts which operates on 32kHz LSI and some maximum ratings are also given in the datasheet. Is i...
SD card not working after adding custom keyboard on multiple screens
I am using SD card with SDIO interface in 1 bit mode.Previously it was working properly. But after adding custom keyboard on multiple screens SD card suddenly stopped working (Getting FR_NO_FILESYSTEM error while debugging).When I removed custom keyb...
HardFault_Handler does not work in error injection
Dear all, I am trying an error injection for an STML432KC nucleo board of my own. When program is running, I change the SP value in order to inject a Hard Fault.When Hard Fault routine is called after this error injection, function collapses due to t...
"Reset value" does not correspond to the register value in debugging.
Hello, I am using a STM32L471QGI6 MCU and its reference manual (RM0351) is:https://www.st.com/resource/en/reference_manual/dm00083560-stm32l47xxx-stm32l48xxx-stm32l49xxx-and-stm32l4axxx-advanced-armbased-32bit-mcus-stmicroelectronics.pdfRegards the "...
STM32 on 1.8V - I2C with 3.5 PullUp
Hello,my STM32 is running with 1.8V and is connected via I2C to another chip. The I2C has an level of 3.5V (connected via pullup to 3.5). I now have communication problems. Is there any limitation for maximum voltage for the high level of I2C on STM3...
