I2C

This Datastream module enable to register the datastreams of I2C Hardware module.

This datastreams corresponds to the I2C devices connected to the device.

Dependencies

This module requires the following modules:

I2C Hardware: Provide an implementation of I2C Service that the datastream module need to provide information of each datastream.

Configuration

To configure I2C Datastream module, a file named es.amplia.oda.datastreams.i2c.cfg must be created with the next parameters for each input channel that you want to register:

name: Required parameter. Identifier name of the datastream.
getter: true by default. Enable the option to use this channel as datastream getter (have to check the value manually every time that want to know actual value).
setter: false by default. Enable the option to use this channel as datastream setter (have to send a operation to change the value of this datastream).
device: Required parameter. Identifier name of the i2c device hardware
min: 0 by default, if min > max then min = 0. Specifies the value that datastream will take when the hardware channel value is in the minimum of the range.
max: 1 by default, if min > max then max = 1. Specifies the value that datastream will take when the hardware channel value is in the maximum of the range

es.amplia.oda.datastreams.i2c.cfg will have a similar format to:

lightData=getter:false,setter:true,device:lightDev,min:0,max:10
temperatureData=device:temperatureDev
