Padauk port of TPS from electronic-labor.de

Padauk-TPS

Padauk version of Elektronic-labor TPS

This a port of the TPS system to a Padauk PFS154-S16 written in 'Mini-C'.
As this chip has no onboard EEPROM an external 24C02 I2C EEPROM is used.

Important reset for this system is by power cycling

The port mapping is as follows:

1. PA0 = PWM output
2. PA4 = ADC using the built in comparator
3. PA3 = I2C Clock
4. PA5 = I2C Data
5. PA6 = Switch1
6. PA7 = Switch2
   
7. PB0-PB3 = A1-A4 and LED outputs
   
8. PB4-PB7 = E1-E4 inputs
   

Timer 16 is used as a 1 Millisecond interrupt for the wait instructions
Instruction 5-9 is now PWM with the A register representing the pulse width
Instruction 5-10 gives servo style PWM between ~ 1 and 2 milli seconds.

Added Schematic, protype picture and a couple of videos of the ptotype running
