Re: cannot rescue two 328P-PU chips

It seems that the chips are indeed bad. If you'd like, I can double check them on my setup - send me a PM and I can provide a return shipping address.

Re: cannot rescue two 328P-PU chips

Did you change the MEGA variable in the sketch to '1' and recompile/reupload to your Arduino Mega?

Re: Looking for feedback...

If you use the Rescue Shield with an Arduino Mega, make sure you edit this line in the sketch and change the 0 to a 1, then recompile and upload to the Arduino. Make sure there is no chip in the socket when you upload or run the sketch! // User defined settings #define MEGA 0 // Set this to 1 if you...

Re: cannot rescue two 328P-PU chips

Are you able to reset the fuses with the rescue shield? What happens when you try to set the default values (0x62 0xDF)?

I've seen chips like your chip 2 before - once the device signature is corrupted the part is usually not recoverable.

Re: Raising the frequency of a quartz crystal

Berj - That is a great article. Thanks for sharing the details of retuning crystals. I never realized that the crystal was just clamped in place in the old style housings!

Re: Upgrading MPD required for AAC stream format?

I don't think it's a given that a newer version of mpd can't be made to work on the router. That said, I have not tried compiling code for this router in several years, so I'm not sure what the current state of openwrt is. I suspect it would be a difficult project but might be doable with enough kno...

Re: Upgrading MPD required for AAC stream format?

At this point I would definitely use a raspberry pi instead. The pi wasn't around yet when I did this project back in 2009!
