Also, to clear up a couple of things that were not quite clear to me as a noob searching aimlessly on the internet, this does require a nF. It may also start running random piece of the flash program. Notify me of follow-up comments by email.

If then the problem is for sure with your code. You can get rid of it by appending: How can we do this type of programming in Amtega8515 Studios?? Since the communication is serial we need to know whenever the data byte is received, so that we can stop the program until complete byte is received.

AVR ATmega8 Microcontroller Serial Communication (UART) Tutorial

I can get as far as uploading Tuorial to the Mega and then firing up avrdude and initializing the chip, but when I try to flash the actual.

The AVR 8-Bits Microcontrollers External Interrupts

If any of these interrupts are enabled and triggered they are service by an Interrupt Service Routine ISR or Interrupt Handler which is written by the programmer.

I can send data from one chip 1 to other chip 2, I. Whatever the latest version was as of a week or so ago. Any help will be much appreciapted. Maybe a stupid question, but did you modify the fuses to suit your circuit?

See the External Interrupt C Programming tutorial for an example on how this is done. Make sure you dont tutoriall any of the pins 10 – atmega85155 on the Arduino side.
