I am facing an issue connecting the STM32F4 NUCLEO-F429ZI board to an HMI screen that uses RS232 and RS485 communication standards. The HMI can communicate successfully with my computer, but the STM32 board cannot communicate with the computer exce...
Hello ST Forum,We are using an STM32H750I in a current project. This STM communicates via the USART1 with another STM32H750V at a baud rate of 512kBaud. The clock of the STM32H7 runs via an 8MHz HSE (external quartz) at 480MHz. The clock of the USART...
Hello evryone:at the first it is may firt project with STM32, and don't have any experince with this MCU.I have a problem, when I read (with HAL_ADC_GetValue(&hadc1)) the multi channel ADC value in interrupt mode the value is always the same. I have ...
Hello,the SPI does work with NSSP(Negative Slave Select Pulse-Mode), but it does not work if I disable NSSP. As someone pointed out the SPI NSS(P) may only work if the Pulldown of that pin is enabled, but I’m not 100% sure on that one, but it seems t...
Hi,I am working on a project for a STM32G473CE, that is already working with the v1.0.0 of the OpenBootloader with FDCAN in order to flash the MCU.I want to upgrade the OpenBL to the latest version (v6.0.1 : https://github.com/STMicroelectronics/stm3...
I checked the datasheet and there is a memory map of 521Kbyte.But I use the stm32h523VCT6 chip.This chip has 256Kbyte of memory.Can't a chip with 256Kbyte of memory use bankswap?If it can, can you tell me the memory address?
We have an STM32F469IG controller communicating with a similar one over CAN at 500K baud rate. The requirement is to change the baud rate while they are exchanging packets. We clear the SLEEP bit in CAN_MSR and set the INRQ bit. The hardware did not ...
Hi: I'm a "newbie" to STM processors. I have a board with the STM32H745BIT3 processor on it. I'd like to get the board to initially communicate via FDCAN to my laptop. My laptop has a PEAK FDCAN device on it. Is there a base CubeIDE project or .ioc f...
I'm using an STM32H750 MCU to run an application that communicates with a computer via USB in CDC ACM mode. The application uses USBX from Eclipse ThreadX and an external USB PHY (USB3300) to perform high-speed communication. My application works fin...
Please assist on how to resolve this. because if I deploy in the field it is not possible to be hard resetting every time for data to start streaming.Thank you.
