RF serial communication

majik2000

I am trying to set up an RF serial communication between a base station and a mobile boe bot.· I have an TWS-434 on the base station and an RWS-434 on the boe bot. Does anyone have any simple programs so that i can check out if i have a functional communications link.· I've noticed that i will have to write a program for the base in order to send commands for directional movement and i have heard that you can use the key pad on the keyboard to coordinate this action and it looks like i will also have to write some program for the bot itself so that it can receive my commands.· I am learning pbasic on the fly and starting to get a little handle on it. any help would be appreciated from anyone.

Thank You

Jonathan

Majik,

The units you have are pretty easy to use. You can find out if you have a link easily. Send a SEROUT command to the pin attached to the data line of the transmitter over and over in a tight loop. Hook an LED to the data pin of the receiver. You should see it blinking as it receives the data.

I have had some trouble getting the max range of these units with the Stamp. For some reason they work OK with other MCU's. I have no idea why and spent a lot of time trying to find out why.

Sparkfun.com has some units that look very cool for 20 bucks, and they are TX/RX combos.

Jonathan
