Hi, I created a little library and I thought maybe some people here would be interrested :)
I made it mostly for fun but I think some people might get some use out of it.
All the details are on the github page: https://github.com/AlexandreRouma/SIMM
It can: * Read a byte from RAM * Write a byte to RAM * Read a block of bytes from RAM * Write a block of bytes to RAM
I personaly used it to store images that I had to display quickly on a TFT screen. I couldn't use an SD card directly because it was too slow. I load the images from the card to RAM at startup, and then I read them back when I need them.
