Why the uart stops working on stm32h755 device once the core clock has been modified and code has been generated using cubemx. It comes with a BSP code for serial communication (which i tried seperately) , that is also not working once the core clock...
Hi community, I am getting error in my stm32 microcontroller system which is used to communicate data of the sensor uart. Initially everything is working fine the adc data is coming perfect. Able to send data through uart without any error. But afte...
Hello. i'm trying to controll actuator by lin protocol. Which mcu is fit for me? and what i have to perchase more things? (for example, lin transceiver is need nor not, 1 more mcu for master-slave configuration) and which software i can use for it?...
Hi Community,I am getting started with STM32 chips and I recently acquired the 32F072BDISCOVERY dev kit (https://www.st.com/en/evaluation-tools/32f072bdiscovery.html#overview). I downloaded the STM32CubeIDE and have been able to write,compile, and pr...
Hi,I am new to the STM32 world and currently working on the following application on a STM32F103CBT6 @72MHz:1. Collect data from I2C sensor triggered from external interrupt @800Hz2. Read commands (MODBUS RTU) from USART and respond.I set up the uC w...
Hello,I am implementing UART RX reception using DMA, but I am encountering an issue where the data is not correctly updated in the memory buffer connected to the DMA. Below is the code I configured. #define DMA_BUFFER_SIZE 10 uint8_t dma_buffer[D...
Our product uses a STM32H7xx chip, integrate freeRTOS. We want our product can go into STOP mode to save power, and can be waked up from STOP by USART3 receiving data.Below is some related code, but it does not work, our product can't be waked up by ...
Hello,I have an application where I transfer data to and from a PC with a FT232R and a UART. There is data beeing transfered back and foth constantly and asynchrone to another, so it is sending and receiveing at any random time and simultaneously. Se...
With DCMI (with DMA) and USART only 1.5FPS, why is the frame rate really low? The output is set to QVGA and formatted as JPEG.
