Hi,
My PIC of choice, at the moment, is the 16F1825. I am interested in understanding the basics of how I might access more read-only storage for this PIC. I am working with the WS2812B RGB LED rings (and strips) and I am thinking of programming in lots of effects and routines. I've not yet figured out if I would blow the capacity of the PIC, I've always limited myself to what is available before, but I reckon there's a good chance as I build up more and more effects.
I'm asking this question here because I'm positive many of you will have done this before and will know the ins-and-outs, the challenges and hurdles, that come with doing this... what devices have people used in the past to add extra capacity to a PIC? For my purposes, I doubt it needs to be blazing fast, I will not read to write to it once it's set up and it will need to be persistent across power cycles. You might think a little SD card and reader... but I was initially thinking more along the lines of a separate IC. A neat and simple interface between the PIC and the extra offboard storage would be a great boon.
Any thoughts, advice or pointers / guidance will be appreciated.
