Local version of the AttoBASIC project.

Welcome to AttoBASIC, a BASIC interpreter for AVR-based microcontrollers!

Overview

AttoBASIC is a very small Basic interpreter for a very small chip. The interpreter uses on-chip RAM only. Originally targeted and developed for limited debugging, monitor and control use on an ATMEL AT90S2313, it has expanded with the ATMEL line of AVR8 microcontrollers.

Most AVR-based boards from and for the Arduino, Adafruit, Olimex and Teensy(2.0) series (and their clones) are supported.

The current version (2.34) supports the following micro-controllers:

• ATtiny84/85
• ATmega16/32
• ATmega88/168/328
• ATmega32U4
• ATmega644P/1284P
• ATmega2560
• AT90USB128

Older versions support AT90S2313, ATtiny2313(A), AT90S8515 & ATmega163 and are now included in the HEX file builds as is the full source code.

Updates

Version 2.0 and above incorporates many enhancements by Scott Vitale; including TWI (I2C®), SPI, Dallas 1-wire® and DS serial interfaces, a high resolution Direct Digital Synthesizer (DDS) function, a real-time counter, data file management, Nordic nRF24L01(+), DHTxx Humidity and Temperature Sensor and support for UART and USB serial I/O. Support for most Arduino, Adafruit, Olimex and many other products running a supported MCU is possible. Various bootloaders are included with AttoBASIC.
