[Flashforth-devel] SPI FRAM memory drivers

[om1zz <om...@vo...>]

Hi, at
https://github.com/igor-m/flashforth/tree/master/examples
are examples of SPI drivers for FRAM SPI memory (byte, word, double access) working with dspic33fjgp128/pic24 etc.
It is a quick hack to see how the stuff works, and it works.
Needs to be optimised a bit however, asm must be used where applicable in order to speed the stuff up. 
My memories are over 64kB so they have got 3 bytes long address. Currently there is a block number (64kB per block) and an address within 64kB. Mind you have to care about proper alignment as the address step is 1 or 2 or 4 for above types.
More in sources.
