Autus

This is the codebase accompanying the project Autus.

Autus is an automated growth chamber for plants.

Features

Control Humidity inside chamber wrt to external humidity. Control Temperature inside chamber. ( Peltier Heaters/Coolers ) Water and shower plants. Control soil humidity. Monitor water tanks level (Load Cell) /media/uploads/umairaftab/frdm_-_new_page1.png

Code Base Features

Fixed timing and CRC for DHT-11 Sensor. Fixed OneWire bug for ds18b20

Cyclic Executive Scheduler with Priority. Async IPC framework for PC App over bluetooth

Fake RTC systick, I was having some trouble with the on board rtc.
