HR1211 cannot be programmed

AC-DC Power Converters

I am unable to write the parameters from the GUI to the chip in any way. Previously, I tried to import data using the “export parameter” button, but it didn’t work. Now, I am using the “program parameter” to import data, but it prompts an error.

Hi @jck24,

A couple questions:

  1. Are you using the HR1211 evaluation board or your own design?
  2. Is the GUI able to connect to the part? Or are you just seeing issues with writing parameters?

Thanks, Will
