An assortment of assembly

I was given the opportunity to complete a number of projects in 8051 Assembly over the course of UBC's relatively polarizing Digital Logic & Microcontrollers class, CPEN 312.

Using a CV-8052 soft processor installed on an Altera DE0-CV board, I wrote, compiled and tested:

• An 8-bit binary adder/subtractor
• A 2-digit BCD adder/subtractor
• A programmable HH:MM:SS clock
• A programmable HH:MM:SS clock
• A calculator (input, output in decimal)
• A square wave frequency measurement device, and
• A 2-team baseball score tracker

All inputs were using buttons, switches and/or a frequency generator. All outputs were displayed on 7-segment displays and/or an LED array. I also designed and worked with a number of finite and programmable state machines.

This was a crazy introduction to the world of ultra low-level firmware, and I loved it! It was the first time I realized how interesting the world at the interface of software and hardware can be. Will definitely be taking another class like this again in the future.
