I/O Board for the 8051
Advisor: Dr. Donald Schertz
The purpose of this project is to construct an extension I/O board which
contains the components necessary to increase the functionality of the
Manley Design-51 In-Circuit Emulator with Intel 8051 Microcontroller boards.
The current 8051 boards do not provide hardware for interfacing with analog
circuits. This severely limits the scope of student projects which use
the current boards. The extended board has: an A to D converter, two double-buffered
D to A converters, a high current output peripheral driver, a programmable
I/O peripheral interface, eight red LEDs, and eight toggle switches. The
extended board interfaces with the 8051 via a jumper cable, and the components
are accessed by reading or writing to specific memory locations.
