Hey everyone. I am trying to print something on TeraTerm console using USART2. I am using STM32L4R5ZI board for this function. Below is a picture of my .ioc file: Below is the Code in my while(1) Loop: Below is the configuration for USART2 in main.c ...
Hi all,I'm Fairly new to both STM32 and the SPI protocol. I'm struggling to get communication working. MCU: STM32F722RETXDevices: GS12281 & GS12170I have both devices connected to my SPI1 bus with SPI initialized as follows: hspi1.Instance = SPI1; ...
I'm working on a project using STM32U5 and I'm trying to communicate with a TMC2209 stepper driver over UART in single-wire (half-duplex) mode. This is the connections: In order to test the connection I'm trying to read the IFCNT values of the drive...
Hello Team,I am trying to integrate the CANOpen protocol Emergency error codes (EMCY) based on CiA 301, 418(battery module) and 419(battery charger) standards in the STM32L496VG controller. I could see the standard error codes in CiA 301, but I would...
I have a custom PCB using the STM32F042F. I replaced the STM, and now every time I connect the communication chip, the STM32 turns off. The STM does not boot if I first connect the nRF24L01 then power the STM. I am confident my code and the board a...
Hi all, I'm working on a project involving UART communication over RS-485 between an STM32 Nucleo board and a rotary encoder. I'd appreciate any advice or insights on whether my hardware and firmware setup looks correct, and what to check next to ens...
We have to use 4 RS485 interfaces. The first RS485 interface mapped to UART 5 works fine with DE enabled. But we saw, that the same method of configuration for USART 1 and USART2 does not work properly.The DE signals will be continously high. As so,...
Hi, I am interface ESP32 MCU to STM32H757-Eval board SPI communication, ESP32 is master side and STM32H757 is slave side below the pin configure, esp32 side send data but stm32h757 not received in debug mode, how to solve this
Hi,I am working on the STM32G431RB and implementing ABI/Z quadrature signal generation. I’m using a sensor that provides sine and cosine signals, which I read using the ADC to calculate the angle from 0° to 360°. The angle measurement is accurate an...
Dear ST team,I’m facing an issue with my STM32F407-based system connected to a LAN8742A Ethernet PHY. After performing either a software reset or hardware reset, the device fails to respond to ping requests. Sometimes it works after a reset, but most...
