1 Introduction

The principle of the TPS controller is simple. You have four digital inputs E1 to E4 and four

digital outputs A1 to A4. There are also two analogue inputs AD1 and AD2 and a quasi-

analogue PWM-output. A reset input with a connected reset button resets a programme to the

start. The controller is supplied with three AA cells with approx. 4.5 V and can work in a range of

2.2 V to 5.5 V.

For programming, you need the two buttons S1 and S2 and a simple LED display of four LEDs

at the outputs A1 to A4. There is a total of 14 simple commands with associated data or

subcommands. Commands and data are each encoded as 4-bit binary numbers from 0000 to

1111 (decimal 0 to 15) and are directly visible at the display LEDs. The respective number is

programmed to S1 by pushing buttons when programming. S2 switches between command and

data and increases the address in the command line. The entire programme structure is so

simple that you will know it by heart with a little practice.
