onInit()

void Supla::Io::MCP23017::onInit ( )

inlinevirtual

Third method called on element in SuplaDevice.begin().

Method called during SuplaDevice initialization. I.e. load initial state, initialize pins etc.

Reimplemented from Supla::Element.

onTimer()

void Supla::Io::MCP23017::onTimer ( )

inlineoverridevirtual

Method called on timer interupt.

It should provide all actions that have to be executed periodically regardless of other SuplaDevice activities. It is usually called every 10 ms.

Reimplemented from Supla::Element.
