Running Bitlash Demo
Bitlash is an open source interpreted language shell and embedded programming
environment. The preinstalled Bitlash demo was compiled in the Arduino environment and supports
Arduino functions (ie: dw() for digitalWrite()). A terminal emulator (recommended) or the Arduino serial
monitor may be used. See the CDC Bootloader section for details on installing the CDC Serial driver.
The following example saves three functions to EEPROM. It is then run in the background, pulsing the
LED using analog write (PWM):
