WEBENCH® Tools/OPT3101-SDK: OPT3101EVM phase and amplitude is so large

user6406327

Part Number: OPT3101-SDK
Other Parts Discussed in Thread: OPT3101EVM, OPT3101,

Tool/software: WEBENCH® Design Tools

We use OPT3101EVM to dismantle MSP430, read phase and amplitude from I2C interface.

we set target distance is 0.2cm,but we get distance is 3m by phase,

We dont't use gp2 clock, I wonder if the absence GP2 will affect the ranging results? Or some other reason that affects the phase?

Hi,

What does dismantle MSP430 mean? Can you describe in detail what modifications you have made to the EVM if it is not stock?

Best,

Alex

We haven't sample board,so we dismantle MSP430 and use our chip connect OPT3101.

Then we connect OPT3101 RST_pin on 3.3v keep it high, keep gp1 and gp2 is dangling, and no ohter changes.

I use OPT3101-SDK to test , only modify part of host code.
