Hi everyone,
I'm interested in make an inductive sensing application where the main task is to detect multiple moving tags so I need multiple sensor coils.
Every tag must be detected in the shortest possible time, in the worst case in about 1.5 ms.
At the moment I have only one LDC1000 and I wonder if the best idea is to use multiple LDC1000 or the two-four channel capability of LDC1612/LDC1614 and LDC1312/LDC1314. So I ask:
1) LDC1612/LDC1614 can detect moving objects in about 1.5ms or there are some limitation in the usable number of channel due to time transition/delay (I read dwell time interval at page 12 of the datasheet)?
2) LDC1612/LDC1614 have an impressive resolution. There is some internally trade off between resolution and measure time? In this case may I use LDC1312/LDC1314 with a lower resolution?
3) If I use multiple LDC1000 (multiple uC) there are some synchronization problems among measurements like frequency count and proximity data?
4) Which LDC is more suited for my task?
Thanks in advance
Best regards,
Alberto
