Best library/algorithm for low RAM embedded data compression?

[Martin F]

Hi all, thanks again for a lot of good inputs.

We ended up evaluating SEGGER's emCompress vs. Heatshrink. Both were potentially valid, but for our particular combination of memory and speed requirements, it looks like Heatshrink may be the better option (and open source). Thanks again for the great suggestions!

Thank you for letting us know where you ended up. If you have measurements you can share, I would love to see them.

Hi again, we’re getting between 50-70% reduction in the size, which is consistent with what we’re aiming for. For us it was in particular the writing speed that was critical in ensuring lossless logging at the same time.

Thanks.

Same for me - writing speed is important because I want to do this on the MCU which it is doing other real time tasks.
