Hi Ticker, ouch, didn't even read that one :( Would have saved me a lot of time as my first idea was a "jump table". Attached is the new patch and the corrected mdr16 outputs produced with this patch.
So, besides the fields with ??? the only open question is the meaning of the struct bytes in the first table. I guess it will become clear when I try to use the lookup table in the decoder.

You mean something like answer 5 here: https://stackoverflow.com/questions/759707/efficient-way-of-storing-huffman-tree I looked at this earlier trying to work out if it was relevant but didn't make it fit - I should have tried harder. I still haven't spotted anything to determine the length of the 2 /3 byte in before and in the struct for {length} Ticker On Thu, 2021-12-23 at 01:17 +0000, Gerd Petermann wrote: > Hi Ticker, > > sorry, just noticed that something went wrong with copy&paste because > of the \0 character. > Anyway, I think I understand the meaning of the part with the prefixes. > I assume that Garmin reads the first 5 bits and uses this value as an > index into a table > which directly follows the first array.
