Hi,I am working with STM32g491re custom board. With UART communication our STM32 and other MCU communicating.After flashing the firmware with debugger both boards are communicating properly but once power off & on If other board sends the data stm32 ...
Hello!I have a W25Q128JVIQ connected to an STM32F446RE like the following:I am trying to use QuadSPI in Dual Mode, but I am having difficulties reading ANY data, like the Device ID (ABh). This is my code: W25Q_STATE W25Q_ReadID(u8_t *buf) { QSPI...
Hello,Since several weeks I had program loading issues using Lauterbach Trace32 debugger on a STM32H753.It came out it is due to the issue described here: https://community.st.com/t5/missing-articles/faq-stm32h7-sram-backup-sram-content-is-not-preser...
Hi guys,I want to do a dma with HAL library for a 1.3 inch st7798 driver display (uses stm32l476rg mcu)https://github.com/Floyd-Fish/ST7789-STM32I used the library in it works fine. but I want the screen to run faster (no scans should appear on the s...
I am experiencing issues with the ADC and DMA configuration. Specifically, I am encountering unexpectedly high ADC conversion time despite following the standard configuration steps. Below are the details of my setup and the problem I am facing: Prob...
I am asking a question of application rather than capabilities of MCU itself.I hope to build an handheld board that is powered by batteries and using this board update other board's settings, especially date/time configurations.This requires a parser...
Hi all,I am currently designing a board based around the STM32F303xC MCU, and had a few questions regarding information on the datasheet.- For boot modes, the data sheet states the following:"At startup, Boot0 pin and Boot1 option bit are used to sel...
We have a new board that uses the STM32H747 MCU and is based on an existing, proven design.Despite being schematically identical, the MCU on the new board cannot be detected by the STLINK-V3SET programmer and STM32Cube software. For whatever reason, ...
Hi everyone, I'm new to STM32. I'm trying to use the STM32C011x4's internal temperature sensor.I'm doing the same as the website below:https://deepbluembedded.com/stm32-internal-temperature-sensor-reading-example/#:~:text=The%20STM32%20microcontrolle...
Hello, I am configuring a PWM Timer and I would like it to by triggered by ETR, the PWM is a 99 period, 50 duty cycles, with auto reload enable. I would like to have the PWM to be restarted (resync in a sort) at each etr rising pulse. ETR Pulse does ...
