Many users ask me how use the redPlc module nodes (e.g mcp23008 or gpio) without ladder logic.
For this, I develope nodes for get/set the module nodes with data from/to other Node-Red nodes
(e.g Dashboard or MQTT).
Here an Example:
Switches are connected to gpio pin GPIO04 and GPIO17.
Set GPIO04, GPIO17 as input-pullup.
mcp23008 is used as output and drives leds on GP0 and GP1.
Set mcp23008 as output.
GPIO04 turns GP0 on/off.
GPIO17 sets Dashboard switch GPIO17.
Dashboard switch GP1 sets output GP1.
