The reminder of this page is a quick start guide to get two PCs sending messages to eachother in the shortest time possible.

Hardware Assembly

Assemble the hardware (RZ502 or STK541 boards) as described in the Setup of the ATAVRRZ502 Accessory Kit or Setup of the STK541 Kit.

Example Configuration

Both examples have a "config_uart.h" and "config_uart_extended.h" file respectively associated with them. These files should be altered so that the different options are to the user's sattisfaction. It is especially important that the extended example is compiled with different options for node1 and node2, otherwise the address filter inside the radio transceiver will not work.

Firmware Programming

Program the device firmware as described in the Programming the ATmega1281 section. Remember to program your nodes with the correct hardware options (RZ502 or STK541).

PC Set Up

With the steps described above successfully completed, it is time to connect the nodes to two PCs, and send data between them. A convenient way to do this is through Microsoft (r) HyperTerminal. The STK541 will be connected as a virtual com port. You can find the com port number from "start->controlpanel-> Administartive Tools->Computer Management->Device Manager->Ports". The RZ502 kit will connect as a traditional COM port.

Start a new Terminal session, in ex. open HyperTerminal. Choose the correct COM port and set the communication parameters (Default firmware use: 38400 8N1). When the STK541 or RZ502 node is powered up it will send a welcome message indicating that the serial interface is working. Repeat the steps above on both PCs. Now with both nodes up and running, type any message (Ensure that "\r\n") is appended and verify that the message you just sent was received by the other terminal program.
