OPT3101EVM: OPT3101EVM

Part Number: OPT3101EVM
Other Parts Discussed in Thread: OPT3101

I'm having a problem with capturing any data from the EVM. The ports seem to be configured correctly as described in the User's Guide, page 11. Latte starts up fine but when I hit "Start Capture" I can see that the command to start is sent (in the log) but then times out because it never receives any data. This is the message in the log:

"Capture data from EVM timed out -- no data received from EVM. Stopping capture."

Digging a little further in the log I found this:

"

Loading register map based on flash : Register Count 35 Reg Address: 0xB8 Value:0x00018026

Loading register map based on flash : Register Count 36 Reg Address: 0xB9 Value:0x00000478

#Execution Time = 4.14699983597 s

#================ ERRORS:1, WARNINGS:1 ================#"

Could be the problem?

    Hi Brandon,

    This error (flash) is actually expected so this is not the issue. Could you paste the full data log from the log window when you run? Also Latte opens an additional black command prompt window in the background. After running can you also check this window for errors? Can you also provide a screenshot of your COM ports in device manager? This should help be debug this further. Also if you can provide a photo of the front view of your EVM that would be helpful as well.

    Best,

    Alex

    Hi Alex,

    Here is the log:

    Here is a screen shot of the ports:

    Just curious, what should the baud rate be set to?

    Here is the output of the terminal window:

    Lastly, here is a photo of my EVM

    I think that's it. Thank you for helping out. 

    On a related note, I see that the max drive current available for illumination from TX0 is 173.6 mA. I would like to try something to push the effective range out a bit further so I will need more current. I wonder if I can tap the drive signal that is controlling the illumination and use it as a PWM signal to a gate driver so I can drive something more powerful - with a separate power source of course. Any thoughts on this?

    Thanks again,

    Brandon

    Hi Brandon,

    I don't see anything amiss in the logs here. It looks like the software is able to communicate find with the EVM. Have you tried power cycling and restarting the computer to make sure it couldn't be anything strange there?

    Regarding using an external driver this is a possibility. You will need to make sure that

    1) The driver can operate to drive a 10MHz square wave

    2) Crosstalk is tricky if the loop area of the photodiode or LED gets to large and can couple TX to RX. This is an issue with bad layouts even without an external driver so this will be tricky using a driver and you would need to run some tests with your driver to see how the crosstalk comes out. I can take a look at your PCB design to review it if you go this route to try to help minimize needing to do a board respin due to layout issues.

    Best,

    Alex
