Hi there,I have an IIC sensor connected to the MCU. And I read the sensor data at 50Hz.However, there are sometimes some IIC communication errors present with HAL_I2C_ERROR_TIMEOUT.My project is based on FreeRTOS with 4 Tasks, the sensor data collect...
Hello, everybody! I'm relatively new to STM32 microcontrollers and have a moderate knowledge of C programming and a fair understanding of electronics.Over the past few months, I've been learning to properly set up STM32F4 series MCUs, specifically th...
Hello. I have STM32L031 nucleo board: https://www.st.com/resource/en/user_manual/um1956-stm32-nucleo32-boards-mb1180-stmicroelectronics.pdfAnd I am trying to write SHT40 driver for it. I have Adafruit SHT40 I2C temperature/humidity sensor:https://www...
I have a custom PCB with a STM32U575 for which I generate code using STM32CubeMX.I am now trying to get I2C to work. Both the I2C1 and I2C2 channels each have one I2C slave. But for both I get the same problem: the slaves do not acknowledge the maste...
Hello all, I am using STM32H747 in my project, previously I was using HAL library for my project, but now I want to shift my code to standard peripheral library, my question is do STMH7 series support to standard peripheral library if Yes then can an...
Heyho,I'm about to start writing an ethernet bootloader for the H7.I found the F7's LwIP_IAP example, a good way to get ideas how to realize the bootloader, although I'll probably put the new bin into an external SPI flash.As I have an http-webserver...
I am using two STM32H503 boards. One is programmed as an I3C controller, the other as an I3C target. My goal is to have the target send an IBI on the bus and the controller will receive the IBI and then immediately issue a pended read -- there will...
I am using a NUCLEO-G071RB, STM32CubeIDE v1.17.0, and STM32Cube_FW_G0_V1.6.0 with patch STM32Cube_FW_G0_V1.6.2. I compiled and downloaded the timer example TIM_OCActive.Please confirm that the four output signals turn permanently active (high) after ...
I am looking for any advice to do with running the RTC Alarm as a wakeup source from STOP2 mode under ThreadX.I have used the Alarm many times before on different STM MCUs without any issues.1) Setting up the Alarm and using it within a WFI test loo...
In the generated code in main.c file, there are variables that are declared as "private variables" by the software, such as "ADC_HandleTypeDef hadc1"; "TIM_HandleTypeDef htim1". Since these variables are declared only in main.c and not in main.h, doe...
