Hi,
I'm working on my final year project. I'm going to use AT89C51AC3 or ATmega1280. Last term in Embedded Systems course, we used an evaluation board(uses MSC1200Y3) that can be programmed over USB. I searched web site of Texas Instruments and find a application note that explains how to make it(In-System Serially Programming).
I'm wondering that can I make it too with Atmel's microcontrollers?
I have to design PCB, not going to use an evaluation board. So I have to program the microcontroller that I will select. Both microcontrollers have ISP feature. I want to know if i can make programmer over the board that I'm going to design. (For example, when a button is pressed the uC will be in programming state, when another button is pressed, the uC will be in running state.) Or do i have to use an external programmer? I have to program the microcontroller without removing from the board board.
Thanks...
