Re: Upgrade to 1.04 Messed up three chips


I may be way off here, but if programming an older 1.01 chip with the new firmware, does this comment possibly cause the issue.

"Note that from now on we will supply QCX chips with low fuse 0xD7 not 0xF7. The new recommendation will be 0xD7. The old F7 has a 65ms delay on start-up for slowly rising power line but this is NOT required when you are using a Brownout Detector bit since the brownout logic will hold the reset anyway until the power line comes up (ATmega328 datasheet). D7 removes the 65ms startup delay."
