Hello everybody
I want to send data from one AVR to another.
At first I going to send data to computer,to know what I have sent from AVR1(I'd like see what has been sent).
How I can connect the AVR to PC?
I don't know how connect AVR TX pin to computer.
Which uses a softUSB interface without a hardware peripheral. However, the code to implement it is in Assembly and can be difficult to port to other projects.

If this is just a project for yourself to be used on your PC, you should probably stick with serial communication between the PC and the microcontroller as this is the simplest method for PC to mcu communication (the least amount of headaches for you).
I found a site which provides a circuit to interface a microcontroller to a PC using just basic parts available from Radio Shack. Furthermore, the circuit described does not require an external power supply. You can find the schematic here:
I have used it before and it worked perfectly with both an actual serial port as well as a "fake" serial port (a USB-to-virtual serial port converter).
