I've just started playing with the EVM and wanted to see what effect changing the Rp_MIN and Rp_MAX values had on the GUI strip chart graphs for raw Proximity Data and Inductance. I'm using the straight-from-the-box EVM with PCB coil and a 1" square of aluminum foil as target.
The test sequence is:
1) Remove target, hit Start, wait for average values to settle, record values.
2) Place foil target 0.015" away from PCB coil, record values as above.
3) Hit Stop, change Rp_MIN or Rp_MAX, goto 1).
I expected to see the Proximity Data and Inductance graphs change with each significant change to Rp_MIN and Rp_MAX. But they do not. Also, if I go to the register settings page and change their value there, the data shown in the Value column does not change, even if I hit the Read All button. It acts as if the Rp_MIN and Rp_MAX values are read-only. Am I missing something?
Another EVM anomaly: I added a file directory under the install directory for saving the register settings. So I click the Save button on the toolbar, navigate to "C:\Program Files (x86)\Texas Instruments LDC1000 EVM GUI\reg settings", set file name "user_set1.csv" and click Save button. It says a file is created, and I can click the toolbar Open button to reload it. But this file does not show up in Windows; not in Windows Explorer, a command shell, or my file manager utility xplorer^2. So I can't use Excel to examine the saved settings.
