Seeing lockbits in hex from avrdude
The -v option gives, for example: Quote:... avrdude: safemode: lfuse reads as E2 avrdude: safemode: hfuse reads as DC avrdude: safemode: efuse reads as 1 avrdude: safemode: Fuses...

Allowed? Can't see anything in the (m168) data sheet, but looking at "Figure 23-1. Analog to Digital Converter Block Schematic Operation" it looks like it should be OK...and I...

Slow rising signal on external interrupts
ATMega168, Vcc = 5v Is a slow rising signal (10%-90% time = 25ms, start voltage 0v, end voltage 4.16v, definitely monotonically increasing) on the INT0 external interrupt (edge...
