A sixteen-channel scaler was designed with a C8051F020 microcontroller unit (MCU) and INTEL 8254-2 timer-counter chips. Software controlling techniques were used to increase the counting capacity up to 2.8 × 1014 by using software counters, to correct errors caused by frequency changes of the crystal oscillator by adjusting software timer to improve the timing accuracy, and to avoid the potential interference by designing digital filters. ...
