Hi, I am working on configuring LoRa (E22-900M22S) and the MAX3485 transceiver to establish RS-485 communication using the STM32H753ZI. I have connected the LoRa and MAX3485 modules as per the following reference:LoRa(E22-900M22S)LoRa PinSTM32H753ZI ...
Hello everyone,I'm currently working on a project using an ADS8688 ADC IC and an STM32F446RET6 microcontroller.I'm encountering an issue where I'm consistently reading random or garbage values over SPI, even when I'm applying stable input voltages to...
Hello,I'm currently working on an STM32 project using FreeRTOS, and I'm facing an issue with UART2 communication when interfacing with a GPRS module.Project Setup:UART3 is used for debugging (connected to a PC terminal) and is functioning correctly.U...
Hello,I've configured my ADC channels in differential mode and I'm able to do some basic test by connecting variable supply to my ADC pins. The results are coming properly. Here I'm connecting directly to my Nucleo545REQ board. Now when I connect CT(...
I’m trying to interface the onboard ISM43362 Wi-Fi module of the STM32BL475 using STM32CubeIDE, but I couldn't find any proper resources or example code online.
Hello,Where can I find the HAL API files and descriptions of the HAL API for the STM32F411 microcontroller?
Dear Community,I am currently working on managing IGBT switching in the frequency range of 20 kHz to 60 kHz. My setup involves directly applying a PWM signal to a pulse transformer, which successfully drives the IGBT. However, I am encountering an is...
Hi all,I’d like to share with you a project I recently completed – a digitally-controlled linear power supply built around the STM32F030CCT6 microcontroller.The power stage uses a classic analog linear regulator topology, known for its simplicity, re...
Hello! With this Simulink model, containing a MATLAB function to convert the vector of numbers to ASCII, I was able to send a vector of numbers until a length of only [1x20], while with a length >20, the simulink model works normally with the externa...
Hello ST Community,We are currently working on a project involving NB-IoT connectivity using the SIMCom SIM7022 modem, which is interfaced with the STM32L496ZG microcontroller via UART. Our goal is to establish MQTT communication with AWS IoT Core by...
