App AN13694 missing files

bubshowlett — Wed, 08 Mar 2023 16:28:21 GMT

Hi All,

I'm following App note AN13694 working with the LPCXpresso54628 dev kit and GUI Guider.

On page 17 of the app note the instruction is to add spifi_polling_transfer.c (Figure 24)

However I'm missing the demo files, so I'm unable to complete the guide.

Does anyone know where the demo files are?

Thanks, Shaun

Hello @bubshowlett

You can find this file under SDK demo "polling_transfer":

SDK_2_12_0_LPC54606J512\boards\lpcxpresso54628\driver_examples\spifi\polling_transfer

Hi Alice,

Sorry for the delay, I was pulled away to another project.

That was exactly what I was looking for and after a bit of messing around with __RODATA I now have images stored in external flash that are read in as needed.

Once again, thank you

Shaun
