A microprocessor based air pressure controller is discussed. The particular
implementation was designed around an existing pressure measurement, and display unit.
The unit is controlled by a 6809 microprocessor. It is shown that due to the many
functions that the unit must perform and control, a microprocessor based system is a
good choice. The controller is economical since it uses standard chips, yet it is very
accurate since it uses state of the art pressure transducers. Experimental results and the
user friendly interface will also be discussed. A commented listing of the controller
software, and the circuit diagrams are appended.
