I did a terrible thing and accidentally over-wrote the firmware on my OpenSprinkler 1.0. The good news is that my OpenSprinkler displays “hello world” on the serial port just fine! I don’t have access to a ISP Programmer. Is there someplace where I can get the source/firmware for version 1.0?
Thanks!

P.S. – I don’t know if this helps or not, but I do have access to the Standalone AVR ISP Programmer Shield Kit.
