Alternative arduino boards

[Paniwine]

Hello, congratulations for this great project! I own a pair of Uwatec computers: Aladin pro and AirZ, and have succesfully build a unidirectional interface based on HEF4069 chip, from https://damien.douxchamps.net/aladin/ which works like a charm! I have found your work very interesting and would like to build your interface as well, but most link are outdated and to be honest, your guide is a bit difficult to follow. So here are the questions:

• Could you update the links to the software needed? and
• It would be possible to use other arduino boards? I already own a RP2040-zero and several ESP32-wroom laying around and I'd like do make use of them. Thanks in advance and excuse me for mi english!!

Hello, thanks!

Indeed, the project is 7 years old now, so some things may have changed ;-) I updated the README for the broken link, but all others seems fine. I can't update with more up-to-date infos because I can't test anything (I don't have a Uwatec computer) and nobody reported success with new stuff yet.

You should be able to use any Arduino board with a Serial2 hardware port as-is. I can't test, so you'll have to ;-)

For an STM32, I guess use the recommended STM core which you should be able to get via the package manager in the Arduino IDE. There is nothing specific required other than the second serial port. Not sure if the version from rogerclarkmelbourne still works with the latest Arduino. The LEDEffect lib is still available at the link in the README, and is probably still the same?

If you have more specific questions about the build or something, I would be happy to help. Let me know how it works for you!

Wow! I didnt expect even a response (and you did it within minutes), so thank you so so much! I'll go with the rp2040 zero, as it has two UART and has the biggest support (probably!). I hope I can come back here and comment the results (or bring more questions....).

Thank you very much again
