I have modified the (code/form) to include reading the XBee RSSI signal at intervals of one second and display these voltages at the forms terminal window.
I have added Xmd commands Vmd00 - Xmd99. These can send a data string with the command.
You would have to modify the form AND the netduino code in order to support your commands (Ideas).
The vertical progressbar code is from CodeProject at: http://www.codeproje...rogressbar.aspx
XBee RSSI is based on code I saw at http://log.liminastu...m-the-rssi-pin.
I assume if posted, it is OK to use as long as source is mentioned.Added support for viewing RSSI voltage levels received from the XBee (Pin 6)...
I have checked the readings received using a FLUKE 97 50MHz scopemeter (Old but sill works well).
The data shown at the windows form is reasonably accurate with respect to the scope measurements.
The form also has a TEST signal output that is a square wave sent to the XBee serial port. See this code.
I used it to send the square wave to another XBee receiver as an experiment.
(The continuous square wave is (ASCII upper case 'U' - binary 01010101) Approx. 200Hz square wave at 9600 baud.
-For the netduino 'reset' I use a jumper wire from netduino pin D11 to the RESET pin.
-XBee RSSI Pin 6 goes to netduino Pin A0.
-XBee serial to netduino D0, D1.
-LCD serial data from netduino Pin D3 (Serial Enabled 16x2 LCD - White on Black 3.3V sku:LCD-09067 This application contains Tab pages (Analog I/O and Digital I/O) that use buttons and checkboxes.
This application does NOT use them. They are for a future project.
