Logo and initial info screen as seen in UEFI setup

[Sci-Mon]

1. I just thought that it might be useful to create a Micropython logo with characters only instead of a graphics file.

2. As Micropython is in fact an entire OS, my idea is to show info next to the logo that is loosely reminding on the UEFI setup main page and the welcome screen of a C64.

3. The information could be even further extended to show peripheral (I2C) devices detected from a lookup table

I use this as initial info shown in the shell for my current project I am working on.

Let me know if it is any use of it (in documentation or code itself).

I really like this design. But it must be sure, that every character could pass thru every simple terminal program. (UTF8, ansi). (my2cents)

that every character could pass thru every simple terminal program.

I was thinking along similar lines, but every * every = ♾️

I grew up coding character graphics on green or amber 80x25 displays, after soldering in the 8th bit memory bank in my dad's TRS-80 so I could use lowercase.

So yes, this is cool 😎

For now I'd settle on a list of known good font + terminal combinations.

Could be a mip installable module with a simple api to generate the logo lines based as a list of strings.
Optionally add simple I'd strings already available in os/dus/platform
If i want to add petechial information, Id rather add that myself rather than potentially leaking/destroying I2C busses.

Nitpicking:

• Wrt to the layout, in the Markdown rendered sample above I see some distracting horizontal empty lines
• the bottom line appears skewed

Totally agree: If the device is rather (pre-)tending to be a lil computer as such, it might be fancy. For devices with little storage capability, it is pure overhead.

Same for me - but different. I started programming on a Commodore CBM 8032 and drawed things in PETSCII.

Possibly, the logo is getting distorted because of the four characters that are used to draw the "head of the snake". I noticed the same on a M$ Windows 11 Computer opening the code in notepad++ with some monospaced font. Those chars showed up in double size.

Alas! It's unbelievable how many times the use of character sets has changed since TRS-80 and Commodore times, and we're still struggling with it to be compatible.

Strange enough, even if I connect via minicom and force 7-bit mode - at least via USB /dev/ttyACM0 - everything is diplayed fine. Guess that it would be different over a real serial connection.

Anyways, I just wanted to share my thoughts and logo design.

I see the point. Possibly it could be checked by REPL if Unicode is supported?In my oppinion, in 2025, Unicode support in Terminals must be present. In reality, combined with Windows and other OSes, fonts etc..., I've already  experienced the contrary. Am 03.12.2025 11:59 schrieb Stefan ***@***.***>: I really like this design.

The logo is trademarked, so one might have to be careful how it's represented.

It was just an idea of mine.
Probably it is advisable to remove the logo and close this discussion.

[Josverl]

Or ask permission...

[Sci-Mon]

Good thought. I am new to this. How this is done and who should I contact?

If you fear having problems with unsupported font on different terminal emulators you can "draw" the logo with letters

Please contact @dpgeorge, (and please allow some time for his response as its release season)
I do remember the TM being discussed previously, but can't find the reference.

• I did find code submitted by Damien to draw the logo using framebuf
• combing that with the framebuf REPL emulator by @easytarget

I get a very well rendered logo:

opy/paste to text/markdown here is still wonky though

Besides the discussion about the Logo:
The initial info looks useful, but IMHO it should be optional and NOT displayed at every boot.
