Mega2560 not responding to programmer

· Gepostet: 29.01.2016 - 22:58 Uhr · #1

Hi,

I have a Mega2560 that will not respond to the programmer either via ISP or JTAG.
I did program it once and I think I must have set a fuse somewhere. Oops.

Any ideas on how to establish communications again?

Kind regards,
Neil.

Hi nwrightson,
no change. Only 19 Pin high voltages parallel programming mode can restore it.

Hello Neil,

I always use:

Code

define_fuses
Override_Fuses;
..........

If the fuses are correct defined there will no accidental change in the fuses.
Use XMegas! They never can be bricked!
