M5Stack

Anyone tried to do anything with these?

https://m5stack.com/collections/m5-core

I just ordered a couple. I was thinking it would be a nice next step to my little information display - this time with something that would allow me to cycle through a few different displays at the nav station.

One thing I intend to check out is the sunlight readability of these. They are pretty small, but might provide a nice, small, somewhat portable display, and even perhaps a control for something like autopilot. They have battery backup, a small speaker, three buttons, a display, and reasonable GPIO access. All in a nice little case, that can be stacked with other modules.

Looks really interesting, thnx for the link. Made something similar with an LCD display a while ago as a test for a mobile display for single handing but this looks much better Smile

Still a lot of work to do, but this is what it looks like now. The menu system is fairly easy, and I just took the code from my other MQTT info display. It connects wirelessly to an AP, then to an MQTT broker on the PI. For testing, I'm using my laptop. The menu library includes a nice system for setting and saving WiFi passwords and getting time from an NTP server. I'll have to work on getting that from the GPS, among many other things!

I wish the display was about 50% larger.

If anyone is looking for a great little pre-packaged ESP32 to use for things like remote wireless sensors and that sort of thing, Banggood has the little M5StackC for only $8.99 USD until July 15.

Did you stick with the M5? They look pretty interesting.

Here is my version of M5Stack Boat Display. I looked at abarrow's code (it was very useful) but ended up with quite different.

GPS/Wind displays so far.
I might add AIS in future. This display connects via TCP to SignalK NMEA stream or to KPlex. (without need for MQTT)

This is how it looks: https://bareboat-necessities.github.io/m...tt_m5stack

The code is here: https://github.com/bareboat-necessities/...at-display

Thanks,

It looks great! I spent some time getting mine to work with websockets and SignalK. I used it recently on a trip down the coast.

It works, but I still need to spend some time cleaning up the code and adding some error checking.
