MCP23017 and boot state
Posted: 17 Oct 2016, 15:38
Hi.
I have a question.
In my system i have a MCP23017 connected to nodeMCU for lights control.
i have set on it 8 input and 8 output.
The output depending from the inputs.
The system works well but in the reboot MCP bring to 0 all the outputs..
Is there a way to read the input on boot of nodeMCU and Then command the outputs? like a rule in ESPeasy
