Playing with a new, and impressive, board.

The Adafruit Grand Central is an impressive beast, but in the familiar layout of a good ol' Mega.

Here I am exploring a Max7219 based 8x32 LED display matrix and the MD_Parola library... Yes, an Arduino library that "just worked" with the SAMD51 based GC.

Just published the latest Arduino library in my easi-series. This time it is a library with demo code for the MAX7219 7-segment LED display driver chip.

Full details in the GitHub repo...

Enjoy!

As I work on my #Kim1 emulation project rabbit holes, I am having a lot of fun with various LED 7 segment displays, or rather the #Arduino library code for the driver chips!

I already have a library for a Gotek 3 digit display that uses a #TM1651. I wrote this 6 months ago while in a rabbit hole as I upgraded my Gotek.

I am adapting it for a 6 digit display that uses a #TM1637, and for an 8 digit display that uses a #TM1638.

And I am also playing with an 8 digit display that uses a #MAX7219.

Mein #Scrollbox Nachbau mit #ESP32 schreitet vorran: Müsste noch ne Monospace Font für den #MAX7219 suchen und ein paar grobe Code Fehler ausbessern (Aktualisierungs-Interval und OTA funktioniert noch nicht).

Dann mache ich es public auf Github 😇

Writing a python driver for the MAX7219 and finding slightly hidden features is a lot more interesting than this headline suggests.
