I am having the same problem. I am using the LDC1000 EVM and reading data directly (serial IO). All default settings as far as I can tell, but the EVM documentation is not clear on how chip settings are handled. As my slowly moving target approaches the coil the reading gets "stuck" at 10922 for a while and then continues. I am no seeing it jump ahead after this however; it just continues upward from 10922. My overall plot runs from about 10000 to 28000 and the part that is stuck at 10922 is about 5% of the total plot.
Two clues about what is going on:
1) In all other data blocks of 512 readings there is some variation from reading to reading. For the blocks that read 10922 there is not variation: it is really stuck.
2) 10922 base10 is 10101010101010 in base2. Can this possibly be coincidental?
Having spent a few days working with this device I now don't know if I can trust any of my readings. The rest of the curve looks generally correct but has a number of small odd features that repeat from test to test. Are these true measurements or artifacts of the sensor?
Actually I don't know if the problem is with the LDC1000 or the programming on the EVM. I see that the previous post has not gotten a reply in over two weeks. This really needs to be addressed. Thanks for any light that can be shed on this problem.
