The controls just described can be simplified with the help of the program promo. 11 subroutines are permanently stored in the address range 1600-1700. They are used to control functional models that are produced, for example, from standard construction kits. The output of the "control language" requires the universal interface for motor control on port 09 because of the bit assignments.
A / D converters can be operated via the port addresses 0A and 0B. By choosing suitable sensors, for example, light, heat and pressure can be read into the computer as voltage changes, the values can be evaluated and the actuators - in this case DC motors - can be controlled in digitally operating control loops.
The control language works with the following bit assignments:
Bit D0: Motor 1 on / off
Bit D1: Motor 1 right / left
Bit D2: Motor 2 on / off
Bit D3: Motor 2 right / left
Bit D4 and D5 not used
Bit D6: magnet or similar on off
Bit D7: lamp, buzzer etc. on / off
