Serial connection RS485 with EVAL-CN0359-EB1Z Rev. A

Question

Good afternoon, 
 I am trying to get the measurement of the conductivity using a serial connection RS485 and a ASCII protocol. The problem is that, using the command 'poll' the string given back is too big for the function on the program I am using to read ( it only read half of the response) and I need a way to have, using a command, as an answer only the measurement of the product, and not also the setting so that my program (openPCS of Ascon technology) can fully read the measurement. 
 
 Thank for your time, Angelo

Hi Angelo, 
 Thank you so much for providing the details. 
 To modify the printed characters when the "poll" function is entered, you would have to try and modify the CN0359 Rev. A source code which can be found here . 
 Specifically, lines 55-119 of the cmd_poll.cpp file define the output for the "poll" command. You can modify this section based on what will work on the requirements of your setup and to customize what is displayed in your serial terminal. 
 
 Link to cmd_poll.cpp: https://github.com/analogdevicesinc/EVAL-ADICUP360/blob/main/projects/ADuCM360_demo_cn0359_reva/src/applications/command/cmd_poll.cpp#L55-L119

To build and debug the code, you will need CrossCore Embedded Studio and a J-Link debug probe (or a similar programmer) to program the CN0359 board. More details on the software setup can be found here: https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/CN0359#software_programming 
 Let us know if you need further assistance. 
 Regards, Andy
