Other Parts Discussed in Thread: LM8335EVM, LM8335

Hi. i'm gak young.

Before i bought your product about LM8335EVM.

But, i don't understand how to control your product.

To control LM8335EVM, it is connected to computer. And i should use GUI to control it.

Product LED turns on, and serial number is happened in GUI program.

However i don't understand register read/write. In fact, i think that it is right on me, but the result is not happened.

Please give me some example about LM8335 GUI to understand LM8335 register access.

I don't want your description in user guide(LM8335evm) at your hompage, I have read this already.

thanks.

  • Hello Gak

    The register address is selected by using the Register Name dialog box in the LM8335 Register Access section of the GUI. If you cycle through the various selections you can observe that the Register Address and Register Description is updated.  Example selecting PROD_ID will change the Register Address to 1D and the Register Description lists the MIPI RFFE Product ID Register description.  If you click the Reg Read button the Read Data will be updated to show the actual LM8335 PROD_ID of C4. 

    Please try the following sequence:  In the LM8335 Register Access section of the GUI screen select CNTL_REG in the Register Name Dialog then Click Extended Read.  The box to the right of the Extended Read button will be filled with the following data: 00 00 FF FF FF 00 00 00.  Now if you click the Extended Write button the first five registers will be written with the data in the box to the right of the Extended Write Button ( 00 00 FF FF FF 55).  Now click the Extended Read button again and the box to the right of the Extended Read Button will contain the following data: 00 00 FF FF FF 55 00 00

    Best regards,
