The RC2 version of Bitlash 1.0 is available for download at http://bitlash.net
Bitlash is a development and prototyping tool for those situations where you need to bang some bits on the Arduino but writing a sketch in C is premature. The Bitlash command language is very similar to Arduino C and includes a large repertiore of the familiar Arduino C functions so you can hack your hardware from the serial command line or even over the internet via telnet.
You can store command sequences in EEPROM and autostart them at bootup, making the automation and maintenance of small applications very easy.
This version contains a bug fix to restore proper handling of escaped characters in string constants. Hat tip to the crew at Rugged Circuits for finding it. You should take a look at their very nice GATOR Plus+ board, which runs Bitlash.
