Other Parts Discussed in Thread: EVM430-FR6989,
Hi everyone,
I'm trying to make a desing with the ESI of EVM430-FR6989 with 2 sensors, and I don't know how to choose the coils correctly. I've read the documentation of TIDA-010050 and "Method to Select the Value of LC Sensor for MSP430 Extended Scan Interface (ESI)".
Our features are the following ones:
- Diameter of the semicircle: 12mm.
- Distance from the disk to the sensor: between 8-10mm.
- Sample rating: 50 Hz.
We need to use external coils instead of internals. I've seen on the case of d=4.2 mm, diameter of 11mm and sampling at 12 Hz, you used 235uH but the value of the capacitor doesn't appear and I don't know how to choose my values correctly.
Thank you in advance.
Best regards
Samuel
