STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi all,I'm porting a project from a F072 (Nulceo-F072) to a custom PCB with a STM32L072.The board is going well, except when I try to use the USB (CDC mode).When I plug it into my PC, the OS can see it - Bus 006 Device 072: ID 0483:5740 STMic...
Hello,Using a STM32H743ZI - rev. V.I'm using ADC3 to convert 4 channels in regular conversion mode, with a 2.5Tcy sampling time, 10 bits, sync clock /2.The measured conversion time is quicker than expected so I'm suspecting something wrong...CPU cloc...
I am still new to STM and I am trying to perform a task on timer, I have written my code to configure the clock the my desired frequency and also I have written the code to set up my timer but when I downloaded the code to my board (stm32g070rb), my ...
Hi What is the most efficient method in program logic to generate a sine wave using an H-bridge with an advanced timer?I am using TIM1 on an STM32 microcontroller, which has two channels (Channel 1 and Channel 2) and complementary outputs. For genera...
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...
