Original question:

LDC1612: ESI + LDC Inductive Linear Position Sensing

LDC1612: ESI + LDC Inductive Linear Position Sensing --- Distance measurement

Part Number: LDC1612
Other Parts Discussed in Thread: MSP430FR6989

Hi Nicole,

Thanks for your feedback and confirmation!
I also would like to confirm two questions with you below.

1.May I see the distance data change in LCD display on MSP430FR6989 LaunchPad? Or I only see the distance data from “Data Streaming” function in “Sensing Solutions EVM GUI”?
2.Due to our BoosterPack board be doing layout process, I want to confirm with you previously that we can see the chart “Inductance vs. Linear Slider Position” like figure 23 in datasheet “ESI + LDC Inductive Linear Position Sensing” by using “Data Streaming” icon in “Sensing Solutions EVM GUI”? Or we need to use other icon in this GUI or else use other GUI?

Would you please correct my description ahead if my understanding is incorrect.

Best regards.

Daniel

    My understanding of the MSP430FR6989 LaunchPad is that you will be able to display distance data using the LCD display. Please see section 5.3 of the ESI + LDC Inductive Linear Position Sensing Design Guide for the LDC sampling process.

    You will be able to calculate the inductance value from the raw data by using Equation 1 and Equation 2 in the ESI + LDC Inductive Linear Position Sensing Design Guide. Although I believe it is possible, I am not familiar with using the Sensing Solutions GUI for this application and using the built-in "Data Streaming" icon.
