Replacing the well known dot matrix type HD44780 based LCD displays with mobile phone graphical screens has a lot of benefit.
- The ability of showing more complex graphical information instead of plain text
- Mostly the smaller displays are using some sort of serial interface, which makes interfacing much easier.
- We can choose colour displays if we like
- They are extremely cheap, or even for free
I made these drivers for LCDHype, but they can be easily ported to anything else.
A digital room thermostat is a simple equipment which regulates the temperature of a system so that the system's temperature is maintained near a desired setpoint temperature. The thermostat does this by switching the heating devices (a gas boiler in my case) on or off.
The unit also features a chart, which shows the last 1 or 10 hours of temperature data.
