I have the Arduino Decimilia board with the AtMega168 chip. From the IDE,I compiled and uploaded MPGuino version 700 with no problems.
I have a Hantronix HDM16216 Display. Powering up or resetting brings up the backlight in a steady state. Am using digital pin 9 for backlight control. There is a steady stream of pulses there. They don't change when pressing the middle button. Nothing appears on the screen. Pressing on the right and left buttons a few time appears to lockup the program according to the led's on the bd.
I enabled debug mode in the sketch. Sketch size was then too large. Then disabled all debug stuff but the serial online message. Sketch size was just under allowed. The online message appeared at the serial port either With the IDE serial monitor or Hyper Terminal.
I built the parallel ISP cable just in case the bootloader was corrupted. Reprogrammed the bootloader in the chip with no apparent problem and then uploaded the sketch again. Problems still the same. Wanted to program chip without the bootloader using the parallel ISP cable. Couldn't seem to get the preferences right to use the parallel ISP cable. I've got a couple more 168 chips coming if that's the problem. Otherwise I'm at a loss as to whats wrong.
