Wideband lookup tables

Post by ronny »

Hi,

what is the maximum count of items for the wideband/AD-Channel lookup tables?
Perhaps this information could be added to documentation.



thanks Ronny

hi,

i played a little bit with the lookup tables and it seems that more than 200 lines (+ first line for the Channel Tag) are not possible.
i added my test lookup table.
Max value nistune shows up is 203 for channel 1 but the AD-Unit sends 0x3FF for this channel (= 5Volt)

With the attached lookup file i expected nistune displays 300 at 5Volt Input.

It looks like Nistune ignores the rest the lines greater 201 in my file.


kind regards
Ronny

okay I can easily increase the lookup size to a larger number (say 1000 lines?)

hi matt

i do not really need this big tables at the moment.
i stumbled upon this table issue by accident. (i was to lazy to make a reasonable table size)
A hint in the readme/documentation for max table size is enough.

hmmm 1000 lines? easily? :mrgreen: just do it.


kind regards

just wastes more memory, since I have to allocate memory for the buffer prior to loading a file into it

I've increased the buffer size and max lines to read tonight for next version

was 200 lines btw but only about 4000 bytes of buffer space for the file. Dare say you ran out of buffer first when reading the file
