LMX2820: Example register programming code?

Antenna_Head

Part Number: LMX2820
Other Parts Discussed in Thread: LMX2594

Team-

Do we have any code examples that we could provide a customer to help expedite their controller code for programming the registers of the LMX2820?

Seems like we've already done that and a shame to have the customer re-do it.

Doesn't have to be perfect, just something to get started with.

Please contact me via internal email if necessary.

thanks!

Hi Antenna,

Unfortunately we don't have any controller code to share.

TICS Pro can export all the register values in a text file, user can make use of these values to ask their controller to generate the SPI signals so as to program the synthesizer.

Unfortunately, TICS Pro register calculation isn't helpful here. In this application we need to scan through channels rapidly, not just set the PLL to a specific frequency.

Surely there must be some code somewhere that does this? We have NDA with the customer in question if that's important.

Thanks!

Hi Antenna,

It is not a NDA problem but we don't have the code at all.

What about the source code for TICS Pro?

Hi Antenna,

It should be available here:
