A plugin allowing the Cayenne Pi Agent to read data from and write data to MCP48XX devices (MCP4802, MCP4812, MCP4822) and display it in the Cayenne Dashboard.

Getting Started

1. Installation

From the command line run the following commands to install this plugin.

cd /etc/myDevices/plugins
sudo git clone https://github.com/myDevicesIoT/cayenne-plugin-mcp48xx.git

2. Modifying the plugin

Specify the device you are using by setting the class value under the MCP section in the cayenne_mcp48xx.plugin file. By default this is set to MCP4822 but it can be set to use any of the classes in the cayenne_mcp48xx module.

If your device has fewer channels than the MCP4822 or you do not want the raw channel values to be displayed in the Cayenne dashboard you can disable any of the individual input sections in cayenne_mcp48xx.plugin.

3. Restarting the agent

Restart the agent so it can load the plugin.

sudo service myDevices restart

Temporary widgets for the plugin should now show up in the Cayenne Dashboard. You can make them permanent by clicking the plus sign.

NOTE: If the temporary widgets do not show up try refreshing the Cayenne Dashboard or restarting the agent again using sudo service myDevices restart.
