Hey. This some pid code for the atmega88 that I once used to control a heater. It s purpose
is pretty specific, and I only wrote it to work on the mega88, so the code itself won t be too useful. It is
a good place to start if you re trying to use or figure out pid though.
AN22 details the theoretical and application aspects of the LT1088 thermal RMS/DC converter. The basic theory behind thermal RMS/DC conversion is discussed and design details of the LT1088 are presented. Circuitry for RMS/DC converters, wideband input buffers and heater protection is shown.
The purpose of this project is to make it possible to remotely switch on a Webasto Thermo Top C water heater that is used to pre-heat the heating system of a car without starting the motor.
