Hi I am trying to communicate CAN. I am using two boards Nucleo-G474RE and Nucleo-H755ZI-Q and two MCP2551 as transceiver.On either side, program works for External loop back configuration. ( I did step by step debug to ensure the transmitting data i...
Hello, I'm trying to communicate with a STM32G070CBT6 bootloader, with mixed success. I've forced the chip into bootloader mode by writing a 0xDBFFE1AA to the FLASH option register (by default it was DFFFE1AA). I've verified that this value "stuck", ...
Hello,I'm working with the offset and linearity calibration on an STMH755. My board will run the full calibration at production, save off the resulting offset and linearity calibration constants, and then retrieve and apply them at any new restarts ...
HiI have to connect an STM34 Nucleo board to a TMC2209. I have to setup a single wire UART. Only TX is connected with the TMC board.I transmitted a datagram and when I try to receive the response I get back the initial data I have e sent.Does anybody...
Hello everybody,I'm a newbie on ST processors although I have a deep experience on several other MCU (Microchip on top).I'm using an STM32F051K8T6 with minimal connection (VCC,GND,NRST,SWDIO,SWCLK and a Led) to start developing a porting from an exis...
Hi all, I am trying to establish a CAN communication between stm32f469i and PC. I have used Cube MX to generate CAN driver. I am not getting any data from the stm32f469i. I have also attached code for the reference.
I am trying to read a file from sdcard using fatfs and sdio and output it to i2s8khz, 16bit is output wellBut 44khz, 16bit file is not played properlyThe mcu is using stm32h743dma is using circular mode and the source is belowThank you#define AUDIO_B...
I want to use led with following connection and i remember that I've seen this application somewhere on the Internet:3V3 - LED - RESISTOR - STM32 PINI've seen the max total current output of MCU then is there any max total input current of MCU?
Hello folks,I've been having a weird issue and haven't found anyone else with the same problem, so I figured I'd post here.I have a project for the STM32H735 BLANK. The PCB has an 25 MHz external oscillator (ABM8W-25.0000MHZ-8-D1X-T3) used as the HSE...
Hi,I am trying to use IWDG to function as a 5s timer, IWDG is reloaded every second. In order to test the functionality, I just activated it with default parameters of PRESCALER=4 RELOAD VALUE=4095, and I did nothing else (no refreshing the timer), w...
