Description

This device uses a rotary dial for entering commands and parameters interpreted locally or sent to a specified MQTT broker, allowing for data readout and control of devices working in a home automation system. Previous version (not fully developed) was based on an ESP8266, but since it's a single-core MCU and interrupts cause WLAN disconnect, I decided to port it to a Raspberry Pi Pico W.

Just going through a bunch of powers of two to make sure the display is working correctly and nothing is jumbled.

So, the ADHD was waiting for "better times" stashed under a table in my lab, and I got back to it today! Rewired it and switched over to Raspberry Pi Pico W as the microcontroller platform. Now it's time for some debugging and coding.

Ha, for the moment I ran into some problems with interrupts and I'll be switching it over to a Raspberry Pi Pico and getting rid of the split MCU architecture. It's currently taken apart and sitting there in a Box-of-Discombobulation but I'll really need to get back to it.

Keri, look here, I did almost the same thing, but without a RPi. #Telephone exchange from scratch
