Paul,
The LDC0851 has a switch type output that can be used for event counting. Here is an event counting reference design:

Depending on the mechanical design of the pulley, it might be more reliable to read out the…
This LDC0851 event counting TI design should help you get started:

You can also order an LDC0851 EVM so that you can start learning how it works and prototyping. The EVM features a break-away design so that you can…
Hello All,
The construction shown above will not work. The LDC sensor needs to have an unobstructed view towards the rotating metal. If you have other metal between the sensor and the moving target, the LDC will be unable to sense this. If there is plastic…
Part Number: PGA900EVM Other Parts Discussed in Thread: TIDA-00851 Tool/software: Code Composer Studio Hi good day. I am trying to program the PGA900EVM board with the example TIDA 00851 firmware, I got it to compile, I followed the configuration steps of…
Hello Lorenzo,
If you have a metal target that is rotating a fixed distance from your PCB then you can use an LDC device such as the LDC1612 (slower speeds) or LDC1101 (fastest speeds) to detect the speed.
I would take a look at the following TI Designs…
Hi Robert,
Please also refer to a similar application note using the LDC0851 to detect the rotational speed of a fan: www.ti.com/.../TIDA-00851-LDC0851
Does this sound like what you're looking for?
Thanks,
Luke
Hello Mehmet,
I'm glad to hear that changing the capacitor solved your problem.
With regards to your additional question, "Basic Operation Mode" puts the LDC0851 into a true inductance comparator mode. When the ratio of sense inductance / reference…
Hello Wisam,
generally, the LDC can be used for gear tooth counting. A typical application for speed and direction would involve two LDC0851 switches. An example is here: http://www.ti.com/tool/TIDA-00851-LDC0851 .
However, as your system is proposed with…
Hello,
Can you help clarify the request? The TIDA-00828 is a complete system including the knob, sensors, micro-controller, and 7-segment display to indicate the increment/decrement value. If the question relates to using an inductive-based solution…
