AFE4300EVM-PDK： AFE4300 Weight-Scale

userFT

Part Number: AFE4300EVM-PDK

Hello, i'm trying to use AFE4300EVM-PDK to measure weight, using external load-cells. But the GUI said there is no data to read from the device buffer. So i tried to use onboard load cell to achieve it. But it still said there is no data. I do it according the user's guide and i think my operation is right. Do you have any method to help me?

Thanks

Hi,

Are you able to communicate with the EVM?
One way to check this is to monitor the voltage at "VLDO" pin while enabling and disabling the weight scale signal chain.
Also, look for RDY pin.

Hi,Prabin
I can measure the voltage of 1.7V on VLDO, but how look for RDY pin work?
Looking forward to your replies.
Thank you.

Hi,

You can probe the RDY signal using the test pin called "RDY". It is near the J9 Jumper on the board.
Also, it would be nice if you could attach the screenshot of the error message.
