A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
AVR AttoBASIC - 3x
Three circuits with AVRs, implementing a simple BASIC interpreter.
Richard Cappels made these three BASIC engines. All of them is "serial-based" (i.e. there is no keyboard nor display, just RS-232 terminal). The tiniest one is based on 2313, the bigger has 8515 as CPU. You can try the version with an external RAM (32kB).
