The Box
This controller box was one of my Caltech EE91 senior projects. It was
originally intended to be a ditch day stack controller. It has
an Intel 80C188 microcontroller cpu (an 8088 with a serial port and
lots of IO). It also has a ADC0803 8-bit analog-to-digital converter and
a DAC0830 8-bit digital-to-analog converter (currently unused). It also has
8 latched digital output lines and 8 digital input lines. It is controlled
through commands over the serial port.
Command Set
- toggle auto-echo mode (echo each character received)
- set digital output pins D7..D0 to next value received
- return value on digital input pins D7..D0
- set D/A output to next value received
- return value on A/D
