Hello All,I needed a very fast vector addition routine for the H7 so I wrote it in assembly. However, I discovered that very small changes in the code caused huge differences in execution time. Both of the following functions add a 16-bit vector to a...
I imported the project to CUBEIDE and after building , it is showing below errors.arm-none-eabi-gcc: error: unrecognized command-line option '--no-warn-execstack'arm-none-eabi-gcc: error: unrecognized command-line option '--no-warn-rwx-segments'make:...
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, ...
