Channel Order

[KristalTasha-two]

Hi @joepardue ,
I've been working on a project with the AS7343 and I came across your repo. Great work here.
I just wanted to confirm the order of the channels. In the datasheet, as shown in the snapshot below, the channel order is different from what you have here. Just wanted to confirm if the channels are the same per the order here?

Hi Kristal, Thank you for bringing up the channel order issue with the AS7343 library. You're correct - the current implementation returns channels in SMUX reading order rather than spectral wavelength order, which is confusing for users doing spectral analysis. I've confirmed this is a legitimate issue that needs to be addressed. I'll be implementing a fix within the next 2 weeks that will: 1. Add a new `spectral_channels` property with correct wavelength ordering 2. Update documentation to clarify the difference between SMUX and spectral order 3. Consider a phased deprecation approach for the existing `channels` property I'll create a new tagged release once the fix is ready, which will automatically propagate to the Community Bundle. Thanks for the feedback and for helping improve the library! Best regards, Joe

Hi Joe,
Great, thanks for the clarification. Will be looking forward to the new release. Keep up the good work!
Cheers.

Kristal, The fix was easier than I expected and is now available. I will be using this library for a project I'm doing and and should have it done in a week or two, in the meantime I can send you a link to that github repo if you are interested. Best, Joe

Hi Joe,
That's great to hear. Yes I would love to checkout the fix, that would greatly help. Thanks a lot.

Kind regards,
Kristal

Kristal, Sorry but there is a problem with the F4 channel that I am working on. I'll get back to you when I have it fixed.

Sure, thanks!

[joepardue]

Kristal, Sorry, but this does not work. I posted to the repo: 7/21/25 After a lot of work and digging I find that the problem with F4 and possibly two other channels has not been fixed. The Micropython library does not fix this problem. There is a claim that it has been fixed in Circuitpython, but that has not been verified.It has something to do with the SMUX. I cannot fix this. I WILL LEAVE THIS REPO ACTIVE BUT IT IS UNLIKELY THAT IT WILL BE FIXED.

And maybe it isn't a problem after all. I'll work on this some more. Do you want me to keep you updated?

Hi Joe,
Thanks for the feedback. I appreciate the effort trying to get this fixed. So just to confirm, I've seen some recent commits regarding the spectral channel order.. these can be used right? Or does the problem affect this?

Yes please, you can kindly keep me updated here. I'll be on the lookout for any updates.
Thank you!

[joepardue]

Kristal, They are all the same, except maybe the flicker detection, which I'm not personally using. Do you need the flicker detection? Joe

Hi Joe,
Okay thanks, got it. No I don't need the flicker detection.
I'm just working with the spectral data from the channels.

Cheers.
