I am writing some code that needs to run certain things fast. Also needs to allow 1 interupt to always be se even when serviceing another interupt.
I have looked at using the GCC, but it looks very much like I would have to seriously mess with the interupt code and lots of assembler in it which from may become very boded to get it to work..... Just to be able to use FAT on an SD card easier.
So has anyone tried to do this and what problems were there?
Or is there a key reason why people have not tried to do this yet?
Any good pointers on where to get the info to do it, and which format is best FAT 16 or 32 for cards.
