no, the sparkfun processor will not work with my code on the arduino, or on the standalone. It does appear to work with really simple sketches though.

Could sparkfun be using a different bootloader?

OK, that makes more sense.  I still don't know the answer, but before I was thinking the Sparkfun chip would work on Arduino but not on small board.  

What is the full number on top of Sparkfun chip?

[edit]Something you might try with the Sparkfun m168 in the Arduino is a simple "hello World" sketch to display on serial monitor.  If that is successful, then display to the LCD. This would confirm the Sparkfun m168 really is working correctly in the Arduino.[/edit]

Coding Badly


I'm starting to get the impression that the SparkFun processor is defective.

Does your Sketch use the EEPROM?

Sure is interesting the Arduino m168 uC works both in Arduino and small board both.

The Sparkfun m168 "seems" to load the blink sketch ok, but nothing more complex?  Can a m168 work with the blink sketch and have problems with a full program?  That's why I asked about loading the "hello World" sketch and see it print out on serial monitor, then have it print to LCD display.  If the Sparkfun m168 won't do those from the Arduino board....  I agree, must be a bad chip.
