Matlab and Serial TC-08

Postby RichB19 » Wed Nov 02, 2005 1:51 pm

Hi All,
I'm trying to get the pico TC-08 logger to function in MATLAB. Currently this code runs displaying ans=1 (true) for opening the port when set to the correct com port (4 for this system). It also finds when the logger is ready to send a value when xobj==1. However xp does not change value and so no value for the temperaure is given xp and x are always value 3 as originally set.

I hope this starts some people along programming for this piece of wquipment in matlab and if anyone knows anyway to get these tempvalues please post in this forum.


function []=tco8()
loadlibrary('c:\pico\drivers\win32\tc0832.dll','c:\pico\drivers\win32\tc08.h')
port=4;
calllib('tc0832','tc08_close_unit',port)
calllib('tc0832','tc08_open_unit',port)
calllib('tc0832','tc08_set_channel',port,8,75,10,0,0) %75 equates to 'K'
x=3;
xp = libpointer('voidPtr',x);
for i=1:100;
[xobj, xval] = calllib('tc0832','tc08_get_temp',xp,port,8,0);
if xobj==1
get(xp)
end
pause(0.0001)
end
calllib('tc0832','tc08_close_unit',port)


Cheers

Hi,

Has anyone got a program in the meanwhile that can get the temperature out of the datalogger in Matlab?
Would be nice if you could post it here...

Hi Paul

Unfortunately we do not have any MatLab examples for the TC-08, we only have an ADC-2xx example which was written by a customer.

There may be someone else who can help though.

Best Regards
Sarah
