Mikroprocesorowa karta przetworników A/C C/A

The I/O card described in this work is ISA slot compatible. The card is based on 80C552 microcontroller. It supports 8 multiplexed analog inputs (10-bit ADC), 8 binary inputs, 8 binary outputs, PWM output, one analog output (8-bit DAC). With PC it may be used for data acquisition and control. Functional blocks of the microcontroller such as Timer T1, Timer T2, PWM, ADC are programmable, so the card with its program can work automatically. Exchange of information between PC and the card is based on both systems interrupts.
