Add STM32G431 Internal Sensor

@Mahihassi

Leveraging over 7 years of intensive experience in embedded systems, I, Sardar Hasnain, firmly believe I am uniquely suited for your project. My proven mastery over STM32 HAL/LL or bare-metal programming using the G4 series will ensure a swift and effective integration of the internal temperature sensor, addressing your main need. Appreciating your requisite of code efficiency, I prioritize minimalist code structure while maintaining uncompromising functionality. Additionally, my proficiency in working with I/O systems will ensure accurate configuration and calibration of the temperature readings. Using CubeMX/HAL or direct register access techniques, I will sample and convert the data to °C before integrating it seamlessly into your existing data structure without compromising integrity. By strengthening the UART/CAN publishing routine, your packet format will remain intact while accommodating new temperature fields.

With over 10 years of experience in web and mobile development, specializing in blockchain technology, I understand the importance of integrating the STM32G431 internal temperature sensor into your existing firmware. It is crucial to accurately log and display ambient and component temperatures in real-time to calibrate radar measurements effectively. In my previous projects, I have successfully worked on similar sensor integration tasks, ensuring seamless data consolidation and transmission. My expertise in STM32 HAL/LL and bare-metal programming on the G4 series positions me well to quickly and efficiently enable and configure the internal temperature peripheral on the STM32G431. I am confident that I can meet your requirements, maintain code efficiency, and deliver a successful compilation in STM32CubeIDE. Let's collaborate to ensure your project's success and achieve your desired outcomes. Feel free to reach out to discuss further details and get started on this project together.

I can handle this cleanly within your existing STM32G431 framework. I’ve worked with STM32 HAL/LL and bare-metal on STM32 families (including sensor fusion and streaming pipelines), so integrating the internal temperature sensor into an active data workflow is straightforward. My approach would be: • Enable the internal temperature sensor via ADC (HAL or minimal LL setup to keep code size small). • Configure proper sampling time (important for internal channels on G4) and enable VREFINT for more accurate conversion. • Convert raw ADC values to °C using factory calibration constants (TS_CAL1 / TS_CAL2 from system memory) and apply the recommended linear interpolation formula. • Insert both ambient (external) and MCU junction temperature into your existing radar data structure without breaking packet alignment. • Extend the UART/CAN publishing routine while preserving backward compatibility (either optional fields or versioned payload handling). • Provide clear inline comments plus a short calibration note explaining constants and compensation logic. I’ll validate stability with a timed soak test to ensure no regressions in radar streaming or timing. If you share your current ADC configuration and packet structure, I can integrate this quickly and keep it lightweight.
