## About the Project

Hardware


A custom architecture based on Intel Microcontroler i8051/MCS-51 *(8-bit, 128B RAM, 4x 8-bit paraler ports, 24MHz)*. Seven-segment displays are controlled by additional drivers and their intensity is adjustable by a potentiometer on the back panel. Chassis was custom made by SSI Schäfer, s.r.o. 


All Cirucit Boards are single-side printed: 


LK01-16 - The seven-segment dispalys. 


LK02-16 - The main board embeding microcontroller i8051 and Epson real-time chip RTC72421


LK03-16 - The board contains switches for time setting and a potentiometer for adjusting brigthness of the dispaly.

Software

Software is developed in an assembly language for Intel microcontrolers series i8051/MSC-51. 

Insturction set and manuals are available at:  http://web.mit.edu/6.115/www/document/8051.pdf
