Want to see some real power? Push your text from any server or device on the Internet using the Digi XBee Internet Gateway's remote text sending feature. Use the same methods to send output via Serial.print() from a microcontroller like the Arduino just be sure that the the transmitter's destination address is set to the MY address of the receiver. Reference the serial backpack data sheet to see all the control codes. For example, from CoolTerm use Send String in hex mode. To control the LCD output you can send control codes as well. Whatever you type will be displayed on the LCD screen. Now that you know how to connect an LCD to the serial output of a Digi XBee radio, take a look at our chat example for an easy way to send text from your computer.įor plain text, just send the text itself. Above is a breadboard layout and a diagram of the circuit for your reference.Now any text sent to the Digi XBee should show up on the LCD! See the Basic Chat example for more information on sending text. You should see the LCD's backlight come on. If there's a switch on the battery pack be sure to switch it to the on position. And finally, insert the Digi XBee into the breakout board and connect the battery pack.That way whatever the XBee transmits will be received by the serial backpack on the LCD. The receive or RX for the LCD should be connected to the TX or DOUT pin of the XBee, physical pin 2 as shown.The receive or RX connection will be routed to the TX or DOUT pin of the XBee. Two AA batteries will provide 3V, which is close enough to the 3.3V rating of the LCD to power it effectively. Connect the LCD's power wire and ground wire to the respective rails on the breadboard as shown.(This particular backpack was marked "5V" on the terminal block but the documentation assured us that it was really 3.3V.) We inserted them into the terminal block and used the screws on top to tighten the connection. Because the LCD is using a serial backpack, it will need to be connected by just three wires for power, ground and receive.Connect the battery pack directly to the ground and power rails.We made it easier to attach the battery holder to the breadboard by soldering some male headers onto its positive and negative wiring leads.Next, connect the VCC terminal of the XBee adapter to the positive rail and the ground terminal to the negative rail. Place the XBee adapter into the breadboard and wire up the power buses to each other.If you don't issue this command, the radio will revert to its old settings when it loses power. OK Note: Remember to issue the ATWR command when you're done so that the settings are saved in the radio's flash memory. Here's what your terminal session might look like.N/A (resets the radio to its factory settings)ģ001 (any address from 0 to FFFE will do)ģ (default of 9600 baud matches the rate for the LCD serial backpack) Here are the commands we're going to use to configure the radio:.Launch CoolTerm and connect to the XBee.Insert the XBee into the Explorer USB and connect it to your computer.If you're not familiar with configuring radios using AT commands, review the steps in the Basic XBee 802.15.4 Chat tutorial, which walks you through configuring CoolTerm to program the radios. A DC power source, 2.8 - 3.4V - We'll be using two AA batteries in a battery holder.XBee Explorer USB - for programming your radio.XBee Breakout Board - for your circuit.To hook up an LCD to a Digi XBee for text output, you'll need: It's the fastest way for your project to gain human communications! 2) Assemble the Parts Build this example for inexpensive wireless text output. You can use control codes to clear the display, move the cursor or smoothly scroll the text in either direction. By pairing the Digi XBee with an LCD that has a serial backpack, any text you send to your Digi XBee will show up directly on the electronic screen. Digi XBee radios in transparent mode generate plain text right out of their serial port. An inexpensive LCD text display can be the most economical way to make your project talk to people, and it's easy to make a wireless one with a Digi XBee radio. ![]()
