AFE4404: AFE4404 Hz Change Routine

kim minseo

Part Number: AFE4404

Hi.

I was changing Hz using AFE4404 EVM.

I want to freely change the Hz in code just like when I put the desired Hz into Pulse Repetition in AFE4404 EVM, the 0x00 to 0x1E register value changes.

So I'm curious about the formula for how the value changes from 0x00 to 0x1E when I enter the desired Hz in Pulse Repetition of AFE4404 EVM

Thank you.

Hi,

Would you please provide a bit more info and explanation? It's not clear to me about your question?

AFE4404EVM GUI doesn't seem to require coding.

which particular register address and name are you referring to?

Can you take a look of user guide 4.1.1.5 Low Level Configuration Subtab to see if that meet your needs?

Thanks

Hi.

Thank you for replying.

It means I want to implement it in code, as set in AFE4404 EVM GUI.

So can you tell me how to set up a register when I get a Hz value from the GUI?

Thank you.

Hi,

It's still not clear to me what you need?

Do you want to read value from register? or write value to register?

Which register?

and, what do you mean by "formula"?

It will be nice if you could provide some screenshot to help the explanation.

Thanks
