 +====== 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-C070WR4C.

 +===== 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.
