a complete, multi-tasking data logger built on an STM32F7 Nucleo board using FreeRTOS. Reads a DHT11 and a capacitive soil moisture sensor, performs ADC oversampling and calibration, and displays data on an SH1106 OLED with a custom graphical UI. Includes a resilient, RTOS-aware driver for the DHT11.
