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)
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.
