I'm a beginner of electrical device, but I need to build up a high-speed temperature acquisition system for my physical research.
I have bought an EVAL-CN0172-SDPZ and an EVAL-SDP-CB1Z, and installed the software for CN0172 by following the instruction described here:
I can read the temperature properly, but there seems to be no button or box to change the data acquisition frequency. There is a box for "samples/reading", but it only reduce the rate, because the minimum number is unity in this field.
I appreciate if anybody could help me for this problem.
The CN0172 and accompanying software is really for evaluation of the system. Unfortunately if there is no button to increase the sampling speed in the GUI software, than I am afraid you will be stuck with whats provided.
There is some C code that you can use along with another setup (EVAL-ADT7420-PMDZ and EVAL-ADICUP360 boards) if you are more comfortable modifying embedded code. I would recommend having a look at this demo(https://wiki.analog.com/resources/eval/user-guides/eval-adicup360/reference_designs/demo_adt7420 ) and then seeing if this will help your project out.
thank you very much for your very kind advice. A distributor told me that it enables me to measure temperature at 500Hz, but it seems to be wrong. I'll quickly purchase EVAL-ADT7420-PMDZ and EVAL-ADICUP360 boards and check the instruction guide you recommended.
Thank you very much again for your great helpt!
