+====== CP-IO22 - IO Board Accessory for the ComfilePi 40 pin header ======
+The CP-IO22 is an IO board accessory for the [[comfilepi:index|ComfilePi]] consisting of 22 IO (11 inputs, 11 outputs), screw terminals, and corresponding indicator LEDs.  It can be mounted to the rear panel of the CPi-A/B/S series panel PCs.
+This product cannot be mounted on CPi-C070WR-4C.

+===== C#/VB.Net Control Example =====
+The following is an example project illustrating how to program the CP-IO22 in C# or VB.Net using the [[:comfilepi:index#net_c_vbnet|Mono Framework]].
+{{ :cp-io22:cp-io22.mp4?700x400 |}}
+{{ :cp-io22:comfilepi-gpio-example.zip |Download Source Code}}
+This example PInvoke's the pigpio library.  For more information see the [[https://docs.microsoft.com/en-us/cpp/dotnet/how-to-call-native-dlls-from-managed-code-using-pinvoke|PInvoke documentation]] and the [[http://abyz.me.uk/rpi/pigpio/pdif2.html|pigpiod C interface documentation]]
+.NET Core drivers can be found at the [[https://docs.microsoft.com/en-us/dotnet/api/?view=iot-dotnet-1.1|.NET IoT Libraries API Reference]].
+===== Python Example =====
+The pigpio library also has a [[https://abyz.me.uk/rpi/pigpio/python.html|Python interface]].
+The following is an example illustrating digital inputs and outputs:
+<code Python>
+import pigpio
+pi = pigpio.pi()
+pi.set_mode(4, pigpio.INPUT)
+pi.set_mode(17, pigpio.OUTPUT)
+while True:
+    if pi.read(4):
+        pi.write(17, 1)
+    else:
+        pi.write(17, 0)
+pi.stop()
+</code>
+===== Pin Map =====
+The CP-IO22 pins are connected to the ComfilePi's GPIO header as shown below.
+**Inputs:** GPIO 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 16\\
+**Outputs:** GPIO 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27

+===== Setting the Initial IO State =====
+It may be necessary to modify the ComfilePi's initial GPIO output state to prevent the ComfilePi from turning the outputs ON when the ComfilePi boots.
+Modify the ComfilePi's ///boot/config.txt// file with the following configuration to set the initial IO state. See [[https://www.raspberrypi.org/documentation/configuration/config-txt/gpio.md|GPIO control in config.txt]] for more information.
+<code>
+gpio=4-13=ip
+gpio=16=ip
+gpio=17-27=op,np,dl
