Thanks - I got that yesterday afternoon on the avr-gcc list. This seems like an inconsistency in the header files that should be fixed. Or, perhaps it's something that should be addressed by the preprocessor - giving warnings on undefined macros (though I have no idea how to impl

This used to work, but since I upgraded winavr and changed to mega128 (used to be mega162), my interrupt vector table is empty, like this: 00000000 : 0: 0c 94 6e 01 jmp 0x2dc 4: 0c 94 8b 01 jmp 0x316 8: 0c 94 8b 01 jmp 0x316 c: 0c 94 8b 01 jmp 0x316 10: 0c 94 8b 01 jmp 0x316 14:

Since you're stuck with an optical sensor, let's look at what we can do with infrared. I have a product at work that uses an infrared sensor that I designed. It uses an Osram SFH426 infrared LED and a PD100MF0MP visible-light-cutoff photodiode. The photodiode's resin doesn't let

Rajesh, Check out the IS471F: http://www.junun.org/MarkIII/datasheets/IS471F.pdf It is an optical solution, but it is not that sensitive to ambient light because the light send is modulated and the light received is filtered by the IS471F. The circuit is very simple: you only nee
