Can download my code for the speedo here, if anyone wants it. All you need to do is connect the TX/RX pins, make sure your protocol is correct, maybe adjust it if you need kph instead of mph, and it should work: download

Hi

Install mqtt in the pi

Setup a Python app with a mqtt client on the pi
http://www.steves-internet-guide.com/into-mqtt-python-client/

Setup mqtt client on your M5Stick
https://github.com/m5stack/M5Cloud/tree/master/examples/MQTT

This should be a good start to get mqtt connected on the both devices.

You need to figure out what form you want to submit data to the database? If it is via the network, you need to have a back-end service support to help you process the data. and save data to the database.

It works with Firmware V1.5.1 and above

Don't use it on port A use it only on port B.
Confirmed, the motor doesn't work properly.
I am sure that the unit only works as on or off as it only has an on/off transistor not a PWMable transistor.

@skink said in Pb.Hub and Pa.Hub grayed out?:

@M5StickFreakler

Start the Desktop IDE Version (Offline Version) of UIFlow, then go to "CheckUpdate" there you start the update to the new version 1.0.9.1 then Pb.HUB and Pa.HUB are activated again and you can access them !
You may have to install the software completely again !?

greetings skink

Hi skink

This was my mistake.
I have already the newest version of UI-Flow installed but I didn't realized, that I have to change the Version via the following button too:
0_1588881439270_a3a9a98c-ae4e-4cbc-a6b9-87a1f7035809-image.png

So I have switched to V1.5.1 and now the pa.Hub and Pb.Hub aren't grayed out.
Too dumb of me.

Thank you and best regards
Thomas

@maxbrito Glad to hear that. Yes, sometimes the documentations are not enough especially for people new to M5.

And now is it time to reset your password on the community site

I want to thank @m5stack for tacking action. To setup https on the community site.

@technerdchris said in Pins on Faces module not connected?:

Hi,

I'm wanting to interface my M5stack with external circuits and am using a faces board. Is there any reason that none of the external pins have connections? I check with oscilloscope and there is nothing at 5v 3v3 or gpio 36. I have interfaced with plenty of circuits with ESP32, arduino, and chipKIT, but this is my first attempt with m5stack. When the base has its pins press in to the faces dock, it looks like these pins should be connected...

In the image, the red arrow is pointing to the pins I'm trying to use. Looking at the sticker, the arrow should be pointing at GND. From left to right on the image then should be 5V, 3V3, BAT, RST, and GPIO 36. I first used the header pins in the breadboard to connect and then I went into the pins of faces dock directly with o'scope.

What am I doing wrong?

nothing is on these pins

Please email M5Stack technical about this as they should be working.
