nicer file for logging data

at the moment it is a bit clumsy having three files to use.

I think that I should have one that will do all the logging.

Here is the plan

define the sampling rate

check if there are any channels open and flush them if nessesary

enable the channels

wait 2 sec

read in 1 sec data

close all the rtdx stuff


I have done all this but the reading in really stuffs up the motor. Maybe I cannot sample that fast.

There is some pretty corrupted data in that file:

I will try to have a large buffer so that I only need to read in after logging is complete.

still corrupted

turn off echo to speed stuff up.

here is a list of the strange numbers and their relationship to

16512 16384 128
16512 16576 -64
16512 16512 0
16512 16448 64
16512 16544 -32

0 1

10 1024
11 2048
12 4096
13 8192
14 16384
15 32768


from this table, it seems like it has something to do with unsigned int/ signed int

i have tried changing to uint16 but it does not like

I have tried changing to uint8 in both the m file and the mdl file.

for some reason that fixed things up
