Bad RX pin on ATMEGA1280 chip

Posted by Earl on September 12, 2010 at 5:46pm

The RX0 pin on the chip is fried. Is there a way to program the MEGA on RX1/TX1 instead of RX0/TX0 ?
I also have an isp programmer.

I did try the ISP programmer and it works.
First I load the code on a good mega.
Then use the ISP and read to a file.
Hook up the ISP to the blown mega
write the file to the blown mega.
Now the software is on the bad mega.
Just need to modify the APmega code to NOT use RX0/TX0. Use RX2/TX2

I know the real solution is to replace the bad mega but I have 3 now.
