This time we will connect a Raspberry PicoW to our WiFi, subscribe on certain MQTT topics by connecting to our mosquitto broker,on our PI and display these reading on our Pimoroni pico display pack.
We will also use the buttons of our Pico Display to switch between different views. For that we will use interrupt handlers to get the button press at any time while our Pico is looking for new MQTT messages.
My current aim is to divide this into three chapters.
This is chapter 1: The setup and WiFi connection.
Chapter 1: Setting up our PicoW with the Pimoroni display-W-firmware and connecting to our home WiFi.,
In preparation:
Chapter 2: Connecting to our MQTT message broker, subscribing on certain topics and decoding the JSON messages.
Chapter 3: Visualization of our data on a Pimoroni pico display. Using IRQ for buttons to switch between different views.
