And then my OLED display stopped working!
Was it my code, was it my Nano R4, was it my wiring, or was it my OLED display?
Testing on an Uno R4 with one of the OLED example "Hello World" sketches, I found that it was the Arduino R4 board manager package. Version 1.5.1, all ok, but version 1.5.2, all not ok 🤔
So, clearly v1.5.2 broke something somewhere, but I have no idea what!

Got me a new toy today 😊.
Any cool home automation and IoT project ideas are welcome 🙌🏻.

Ich versteh nicht viel von Blumen oder Geschenken, ich kann nur programmieren und basteln.

Alles Müttern schonmal einen schönen #Muttertag -
Success! Hurrah!
Finished debugging my #ArduinoUnoR4 code and squashed 3 bugs! It is all working perfectly now 😁
Resorted to stepping through my code on paper as it was the easiest way to debug a function called under interrupt (serial print does not work).
It's been a long time since I needed paper to debug, but the errors literally jumped of the pages as I "ran" my code!
My working code now shared via the free #ArduinoCloud.
Now going to get myself a nice bottle of red wine as a reward 🎉

Finally, last night in a moment of clarity, I realised what the bug in my scrolling was, and I got up and fixed it this morning!
The issue was not with the scrolling, but with what I was feeding in to be scrolled.
It was a silly mistake - I got confused with my bytes and my words...
Top tip: when copying bits from an array of 32bit ints, calculate the index and offsets based on 32, not 8😉
Anyway, I was pumped to see this working as it was supposed to all along 🎉

Frische Bastelware zuhause angekommen.
#Arduino #ArduinoUnoR4 -
Been having a lot of fun learning and playing with my #ArduinoUnoR4. The LED matrix is interesting but the library for it is not mature (some functions just do not work). However it isn't complicated, so I was able to write my own led on/off functions that do work. I also wrote led toggle and plot functions.
Now using this board for my 6502 emulator...
In the video, only the 6502 logo is frame loaded using the Arduino library. Everything else is individual led control through the frame buffer.

Say hello to my new lab partner "Arfour". So much potential and all for only 25 of my hard earned great British pounds!
The default script is cool too, and can be easily found on the #Arduino forum.
I will be busy this weekend...
