Serial communication atmega

There seem to be no problem on talking from computer via usb to the arduino board and visa versa. But howto establish a link between avr board and arduino is my problem. I would like to be able to send and receive by both boards. Any help would be appreciated. You have not posted a link to the datasheet for the Atmega32 board. The simplest way to communicate with a Mega is probably by using a serial connection.

Thanks for your links"serial basic". I studied them and copied all in my booklet. I have connected these serial links together but the codes which performs this send and receive is my problem. From computer via serial usb is no problem but from Arduino and another board is the case I need some examples. Connect the TX of the atmega32 to on of the RX pins on the arduino mega don't use serial0 - as that's what's connected to USB serial and it will fight with the USB serial adapter , and vice versa, and connect the grounds as always.

Make sure the program on both boards is communicating on the serial port you're using and at the same baud rate, and you should be good to go - data sent by one will be received by the serial port of the other. If they're both running an Arduino sketch, you'd be sending data with Serial1.

Both the controllers do not share any clock. Since both of them use internal clock of their own. The ATMEGA is programmed to send data with no parity, as the data transmission length is small, we can clearly expect no data loss or error. So we are not setting any parity here. As shown in circuit a button is connected on transmitter side. Thank you very much for answering me!

I can send data from one chip 1 to other chip 2, I. That is two way communication is not happening. I have enable receiver one transmitter in both chips.
