Hi everyone!
I am not sure if this problem is related to this topic. But I don't know
where else it would fit.
 I am using a dspic33fj128mc802 with mplab xc16 compiler. I have to read
data from an ADC at about 1ms intervals. The data that I get is a floating
point number. I convert this number into a string using the function
sprintf. Send out the string. At the PC side I receive and save the data
with putty.exe. Then save the session in a .dat file. I can use this .dat
file with matlab to plot the results.

The problem is that sprintf really slows down the process. I should be
taking samples at about 1ms intervals and because of the sprintf function
this is between 5-7 mseconds. I checked this with an oscilloscope and
without the sprintf function I can get down to even less than 1ms intervals
easily.

If anybody could suggest a faster way to make a string out of a floating
point number or another way to send and receive the data I would be very
thankful.

Cheers
Tomi
