Seeeduino XIAO - Arduino Microcontroller - SAMD21 Cortex M0+

700×526

Seeeduino XIAO is the smallest Arduino compatible board in Seeeduino Family. It is an Arduino microcontroller that is embedded with the SAMD21 microchip. The interfaces of Seeeduino XIAO is rich enough in such a tiny Dev. Board as well.

Key Features

  • Powerful CPU: ARM® Cortex®-M0+ 32bit 48MHz microcontroller(SAMD21G18) with 256KB Flash,32KB SRAM
  • Flexible compatibility: Compatible with Arduino IDE
  • Easy project operation: Breadboard-friendly
  • Small size: As small as a thumb(20x17.5mm) for wearable devices and small projects.
  • Multiple development interfaces: 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, 1 I2C interface, 1 UART interface, 1 SPI interface.

I too have the same issue! Came to the forums with a question, and I can’t start a thread anywhere :frowning:

Assuming it is dependent on real interaction to prove you’re not a bot, I’ve liked a post, and am now posting a reply here hoping it helps!

I must be one of the first people to receive this new 7.5" ePaper Panel too, because I can’t find a single thread mentioning it! Fingers crossed this response gives me the “user level” or whatever I need to post my question in the correct section!

OK can’t find anywhere else to post a question on the XIAO 7.5" ePaper Panel that I have received and trying to setup.

After a couple of days of going around and around in circles of installing - uninstalling all the components I am at a point where I can get text on the screen!!

As far as variables from Home Assistant go I have had mixed results with lockups and Resets required to try another way.

So moved onto using the recommended Puppet Add On in Home Assistant.

Successfully getting the chosen Dashboard shrunk down and ready for the ePaper display.

BUT Every time I try I get this

Anyone any ideas on how to get Home Assistant/Puppet/ESPHOME/XIAO 7.5" paper Panel to NOT REFUSE the connection?

So close to this being useful… at the moment it is ePaperweight :slight_smile:

iirc I ditched puppet as the quality was just not up to what we need for this display. Probably great for full resolution, colour displays, but really not ePaper friendly.

I wish I could tell you what I did beyond that. I basically smashed various pieces of the tutorial at it until I got something useful on the screen, then went and read all sorts of other docs for rendering content and drawing lines and such. I ended up with 3 cycling pages that show my air quality levels across the top of all three, and then the lower 9/10ths of the screen cycle through my plant monitors to display their stats/alerts. I’ve got more plant monitors than I can fit in three pages now though, so I’ve got to go back to square one and figure out how to only render the ones with a “problem”.

Made some progress, have got it running with paper and it is looking very good- well as good as 800x480 can deliver :slight_smile:
If I install the yaml using the manual method and have the ePaper display connected by usb everything installs and works.

Using the Wifi Install always fails with an HTTP connection refused.

Also, seeing issues with Puppet that require me to restart it every few hours - still investigating.
