4-bit SD and daisyDuino? Is it possible?

Troubleshooting and Support

Hello!

I’ve been pulling my hair out over this for days. Is it possible to get a 4-bit SD module working on daisy seed with DaisyDuino, without killing all the RAM or audio chain? I had everything working fine with 1-bit, but really need that extra speed for file loading on startup…

Thanks for any help. I’m happy to post my awful butchered code hah. But maybe there is at least someone with expertise here who can say, “it’s a lost cause, you can’t do that’“ etc haha

Hi!

What library are you using for the SD card reader and how would you like to use it for your project? It’s possible that the library you’re using is not compatible with STM32 boards like Daisy.

hey thanks. I tried both SdFat, and STM32SD. And yea, lots of incompatibility issues hah. Is there a better library to use that would have saved me two weeks of hair pulling? :smiley:

Unfortunately, I haven’t come across an Arduino SD card library that work with Daisy.
I typically recommend using .cpp on VS Code for SD card. I’m really sorry for the inconvenience.

Thanks and yea no worries at all. I just wish I’d have known that before spending the two weeks working at it haha. But as always, not time lost because I learned a lot while failing :grinning_face_with_smiling_eyes:

For now though I’ve managed to get it working in cpp, and soon comes tackling the enclosure hah.
