Raspberry Pico W RGB Matrix Information Display driven by MQTT

PicowPanel

An MQTT-driven Pico W-based information panel using a HUB75 RGB LED matrix display.

The code has been tested with both 64x64 and 64x32 panels.

A lot of the code is shared with my similar PicowTFTPanel project.

Rename the dummy_wifi_config.h to wifi_config.h and edit it to suit your WiFi setup.

• config.h has some basic definitions used throughout the code
• info_items.c has the specific display items and their MQTT topics
• mqtt.h contains the high-level MQTT connection details
• picowtftpanel.c has the pin definition for the AM2302 near the top
• rgb_led_config.h includes the pin connections and dimensions of the display
