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...
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 && ...
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...
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...
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...
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 "...
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...
Hello all! My name is Matt and I am a university student studying EE. For school, I recently designed a board with an STM32405RG MCU and BMI088 IMU. Part of the project is gathering data from the gyroscope and processing it every time step. My origin...
Hello!I am writing a program and am still on the code generation phase. I am having a weird issue where the code runs, but gets stuck in the initialization phase for the SDIO (MX_SDIO_SD_Init). If the SDIO is commented out, the program gets stuck in ...
I have an 1.8V STM32 and an 3.5V MAX31865 which are connected via SPI, I used 10k Ohms pullups on data line to 3.5V. Now the problem is that communication dosen't work. When I increas STM32 voltage to 3.5 V everything is fine. Is there an limitation ...
