This is a complete STM32 Blue Pill project that demonstrates how to read multiple analog sensors using the ADC in DMA mode, and display the results on an LCD16x2 display. The sensors used in this project are:
- LM35 temperature sensor
- LDR (Light Dependent Resistor)
The project also includes a custom LCD16x2 library for interfacing with the Blue Pill using GPIO.
- Multi-channel ADC configuration using STM32CubeMX
- DMA support for efficient ADC data transfer
- Read LM35 and LDR sensor data
- Display results on LCD16x2 using 4-bit mode
- Breadboard-friendly setup
- Clean and readable HAL-based code
