#m5paper — Public Fediverse posts

Anyone playing with #ink #epaper #esp32 ? Complete noob here. Where do you hang out? I want to see what you’re all doing? :) #M5Paper #M5PaperS3 #ESP32S3

Eine Idee: das #M5Paper als Anzeige der #Tibber Strompreise nutzen. Seit 18 Monaten liegt es fast ungenutzt auf meinem Tisch!

Eigentlich nur aller 24 Stunden neue Preise abrufen, rendern, darstellen und deep-sleep.

Playing around with my #M5Stack #M5Paper and now I've created a "remote dashboard". It basically renders a JPG every 15min. Which works great. Battery life is around 10-20 days.

Published the source code on Github: https://github.com/capi/M5Paper_Remote_Dashboard

Made the mistake of poking my head into #M5Paper development and am now paying the price. All I wanted was to play with e-ink, but instead I now find myself staring down the four horsemen of maddeningly disparate development options: #Arduino IDE, #PlatformIO, #MicroPython, and #M5Stack #UIFlow.

I don't want to leave #Emacs for an IDE, PlatformIO doesn't get along with the device, MicroPython is a mess, and UIFlow is a visual code block editor over an undocumented MicroPython API 💀

even with having to do customs shenanigans, I already received the #m5paper.

Got some problems to get #day_light_saving right on my #M5Stack #M5Paper #ESP32 board.

Then I found the example code on the following website, which seems to work just fine 😃

#NTP for the ESP32 including day light saving without 3rd party library https://werner.rothschopf.net/microcontroller/202103_arduino_esp32_ntp_en.htm

Last week I've got a new toy, a #M5Paper #ESP32 Development kit with 4.7" #eInk display.

I had some fun playing around with it.

Poking at my #M5Paper tonight. Gonna get it doing stuff.

I got lost in a research rabbit hole last night, and didn't make any progress on the #M5Paper. That's okay, it's a hobby project, I'll make progress on it when I make progress on it.

It's pretty close to top of mind for me, but I have a few deadlines that are tight enough that I have to let them slip in front.

Sigh
