atinybasic

atinybasic is a straight-forward port of Dennis Allison's famous "Tiny BASIC" from "The People's Computer Company" newsletter circa September 1975. In the spirit of the original, atinybasic does not attempt to be a complete BASIC environment per se. Instead it's meant to be a starting point for building a BASIC suited for a particular project or task. I have added RND, ABS and an array to the basic feature set, but this is more to show how you might add more features than anything else.

Installation

Copy the basic_blink folder to where you keep your Arduino sketch folders.

Setup

By default, the included basic_blink sketch will start a headless BASIC interpreter running a (flash stored) program that blinks the LED attached to pin 13 on Arduino Uno boards. To enable a serial console, change the #define CONSOLE 0 line of config.ino to #define CONSOLE 1. Also change #define RAM 0 to #define RAM 1 and #define FLASH 1 to #define FLASH 0 (this changes the program source from being the onboard flash to the onboard RAM).

Size

Headless, the interpreter only takes up 348 bytes of RAM, leaving the rest for BASIC programs themselves.
