Nodes Categories Information

1. Raspihats I2CHat

DI Read(DigitalInput)

Node used to read a I2C-HAT Digital Input channel state, generates a msg object with msg.payload that is true or false depending on the state of the Digital Input channel.

A polling mechanism is used for reading the DigitalInputs states, target polling interval is 10ms.

DQ Read (DigitalOutput)

Node used to read a I2C-HAT Digital Output channel state, generates a msg object with msg.payload that is true or false depending on the state of the Digital Input channel.

A polling mechanism is used for reading the DigitalOutputs states, target polling interval is 10ms.

DQ Write(DigitalOutput)

Node used to write a I2C-HAT Digital Output channel state, expects a msg object with a msg.payload that is true or false and writes this to the Digital Output channel.

TODO

• Replace polling mechanism for Raspihats I2CHat/DI Read with a interrupt based mechanism
