Other Parts Discussed in Thread: TUSS4470
I'm getting started with TDC1000 and I want to integrate it on my proximity sensor application. I want to make my own PCB with my own controller.
My goal is to detect distance of an object in the range 0 - 4m without a defined strictly accuracy.
Since I'm a firmware engineer I'm very confident with firmware side but not very confident of the hardware side.
I had a look at the TDC-1000 Eval board and at the schematic. Like I said, I'm understanding the logical connection, but I'm wondering if this application is compatible and suits my needings(?)
In particoular, these are my requests:
- Schematic of EVAL should work in my case?
- What mode should I program through SPI? Since mode 0 is for level and fluids and mode 2 is for water flow metering, I guess the mode 1 should work for proximity but I'm not sure because is not specified.
- In the para 9 of datasheet there are several applications, but not the proximity so I can't compare the pictures. By the way, the proximity is stated at the beginnig of the document so I think the TDC1000 is compatible.
- How to set the PGAGAIN and LNAGAIN? Are them required? Do they require a particoular driver-circuit? In the EVAL module is left unconnected.
Are there any application notes or reference schematic to follow?
Thanks and regards,
