Jordan Earls / MbedConsole Featured

A project to implement a console using the Mbed using VGA for video output and a PS/2 keyboard for the input. The eventual goal is to also include tools for managing SD cards, and a semi-self-hosting programming environment.

Dependencies:   PS2_MbedConsole fastlib SDFileSystem vga640x480g_mbedconsole lightvm mbed

MbedConsole is a cool little project to have a self-contained computer all on an Mbed. So far it has VGA and PS/2 support and can stand alone without a computer powering it. Next planned features are SD card support and a lightweight programmable VM complete with a file editor and self-hosted assembler.

You can view additional details about it at http://earlz.net/tags/mbedconsole
