Can you suggest easy way to add extra memory to w7500 for data buffers?
You can copy data into main ram memory, no ? One DMA channel can be used to make a quick copy.
If you’ve not enought ram memory at all, it is possible to add external SRAM. I have tested with a 23LC1024  and this works well … but need a bit of software for copy.
Thank you for your idea. I can still do with internal memory, but it may be very useful in the future.
