Cooling Code


Here’s an early snapshot of the code to drive the radiator cooling fans with PWM output, using the harness fan-switch and starter motor switches to determine the mode of operation. The code (already) compiles to 610 bytes; out of the 1024 available in the ATtiny13A microcontroller.

Field programming operation, battery voltage sensing and the ability to use an NTC resistor for coolant temperature sensing are not yet supported.
