Hi @vgamlc I haven't tried it myself but according to this document the library should be included in the Arduino IDE library manager: Installation painlessMesh is included in both the Arduino Library Manager and the platformio library registry and can easily be installed via either of those methods. Cheers Felix

Hello David wow, nice project! Regarding power supply via 5v bus. There is a function called SetBusPowerMode() which allows to switch between internal 5v boost (default) and being powered externally, e.g. from 5v bus. Unfortunately it is broken and the pull-request I've posted a while ago has not been merged yet. If you're interested you can still give it a try: https://github.com/m5stack/M5Core2/pull/10 Calling the function in setup() with input parameter set to 1 switches to external power and the 5v from the bus are taken to power the Core2. It also charges the battery. e.g. M5.Axp.SetBusPowerMode(1); Note: Without battery installed you'll need to modify the existing call to this function in void AXP192::begin(void) else the M5Core2 cuts itself off shorty after booting. Greetings from Winterthur Felix

Hello Van sounds like a plan - thank you. Glad to help out. Cheers Felix P.S. I am very sorry for misspelling your name previously (fixed now).

I implemented the Nixie tube clock in uiFlow IDE for the M5StickC-Plus device. [image: 1599001318721-clock_h2.jpg] https://github.com/bstein2379/M5StickC-Plus-Nixie-clock Credit goes to @macsbug for the original idea. I just made it easier for new programmers and kids by using the uiFlow IDE.

Really cool and we’ll documented. Being new to UIFLOW, is there a way to get that code into UIFlOW to play with it? Is there a .m5f I’m not seeing? Thanks, Paul

@vkichline Thank you, I'm glad you like it. Once the upload issue is fixed, I'll share the m5f file, anybody then can easily change the color to their liking or infact modify it entirely if desired, there's most likely things in there that could have been done in a better way. (Feel free to point them out, I'm still learning)

@taxfromdk difficult to change the battery. probably to cause damage. so don't do that

Thanks for the info. Solves the issue. So looking at the schematic I would connect to pin 28 for 5V and pin 1,3 or 5 for GND. Cheers.

@rhannink This looks good! I'm looking for a replacement of the Zipato Mini RFID tag reader I've been using the arm/disarm my Home Assistant alarm system. Unfortunately these are sold out everywhere. Your project sounds very interesting but at the location I'm planning to put this, there is no power... Would you think it would be possible to have the entire project (controller + RFID reader + screen) in deep sleep most of the time, and only wake it up when one of the physical buttons is pressed? Is there an estimate about how much power that would still use? Thanks in advance for any reply!

Very Nice

Hi , I used your application before I discovered the M5stack. It was on a fb page for diabetes and nightscout and a fb member was so kind to burn It and adjust the parameters for me. It is an excellent application, thank you ! And now I am discovering myself the m5stack...what an incredible device and There are realy endless possibilities... Maybe Considering things or features to add In future : dark screen and not displaying the value until a button is pressed... need full darkness to sleep a feed with mqtt to connect to alexa and be able to ask the bg level to alexa When m5stack is on (i used it with Smartnest.cz to connect my ENV hat and am able to ask alexa the temperature of poolwater ) Good work anyway and thank you a lot !!!
