FDC2214PROXSEN-EVM: Is it possible to get Firmware, PCB layout, and board schematic of FDC2214PROXSEN-EVM?

Part Number: FDC2214PROXSEN-EVM
Other Parts Discussed in Thread: FDC2214EVM

I am a student studying capacitive proximity sensor and I'm trying to study FDC2214PROXSEN-EVM board.

However, I can't find any data on the board except datasheets..

So, is it possible to get Firmware, PCB layout, and board schematic of FDC2214PROXSEN-EVM?

I really would like to look deeply into the board's schematic and firmware to fully understand it.

  • Hello,

    Unfortunately we don't have that information publicly available for the FDC2214PROXSEN-EVM. However, we do have an application note that has pseudocode for the proximity detection algorithm. In addition, we do have the schematics, layout, and firmware available for the regular FDC2214EVM. The schematics and layout can be found on the main page of the FDC2214EVM product folder. The firmware is included with the Sensing Solutions GUI download and can be found at this file path: C:\ti\Sensing Solutions EVM GUI-1.10.0\EVM Firmware\Older Revs\FDC2x14_LDC13xxRevB_LDC16xxRevB_EVM_Firmware_source

    The algorithm described in the above application note is implemented in the FDC2214PROXSEN-EVM, but this is the only significant difference between the two EVMs' firmware. The FDC2214EVM also has smaller sensors than the FDC2214PROXSEN-EVM, but they can still be used for proximity sensing. You can learn more about the typical relationship between sensor size and sensing distance in this application note.

    Best Regards,
