Key Aspects: - Microcontroller: The project will utilize an STM32 (e.g., STM32F407 or similar) with STM32CubeIDE and HAL libraries. - Sensor Integration: The system needs to interface with up to 4 sensors (specifically temperature, humidity, and pressure) using the I2C protocol. - Data Logging: The data should be logged in CSV format onto an SD card at adjustable intervals (for instance, every 1 or 5 minutes). - Serial Communication: The UART should be implemented for basic command-line control and real-time data streaming. - Firmware: The code should be modular and well-documented, with built-in error handling. - Testing: A 24-hour stability test a...
I'm looking for a talented programmer who can write code for an ESP32. The code should initialize a PCM1862 through I2C and send the I2S data over Wi-Fi as an HTTP stream. All the coding should be done using PlatformIO within the Arduino framework. Potential for Ongoing Work: If you're successful, I may require your services regularly, where I will send you the hardware for testing. Key Responsibilities: - Write code to set up the PCM1862 via I2C - Stream I2S data over Wi-Fi as HTTP Necessary Skills: - Proficiency in C++ and experience with the Arduino framework - Deep understanding of ESP32 and I2S - Familiarity with I2C and HTTP streaming

I'm seeking a skilled professional to develop code for an STM32 chip and create a corresponding GUI. This project involves reading I2C devices, displaying the information on a tabbed RGB display, and outputting data on an RS485 to other local devices on modbus rtu network. Key aspects of the project include: - A tabbed interface for the GUI. - The GUI should display sensor readings, status indicators, and control buttons. - Data on the GUI should be updated every few minutes to every few hours. Ideal candidates should have extensive experience in: - Programming STM32 chips - Developing GUIs for embedded systems - Working with I2C devices and RS485 buses Please note, the data does not need to be displayed in real-time, but rather updated at intervals of several minu...
I'm seeking an experienced professional to assist in debugging and troubleshooting my I2C and I2S communication issues, specifically concerning software integrity with the pCB board. The person needs to work with the customer to help him troubleshoot and add necessary configuration.
