Hello,
I would like some assistance with storing information on a SD card in the format of a text file. This SD card is connected to a 8051 microcontroller. Communication with the card is done via the SPI. I'd really appreciate some sort of #include file or anything that lets me have access to functions such as fprintf and fscanf, fopen, fclose. Also if anyone can tell me weather FATfs (elm-chan.org/.../00index_e.html) files are ok to compile on a 8051.
this micro-controller really doesnt have enough memory to store 1000+ entries in such an array it has (with an external RAM) 64k bytes of data storage AND with a bit of trickery I have made a device with a '51 and 2Mbyte of data storage
if that would be enough, you can get (NXP, SILabs, others?) '51 chips with 8kb of internal RAM

What I specifically have to store is a time stamp (from a RTC) and 2 int values every 1 minute for a month, which comes to about 30*24*60 = 43200 entries. Also this has to be versatile enough to be able to store 4 months or more if the user so desires. This seems too big for any solution other than a few MB of storage. My focus is making sense of that data, so any solution ideea that solves the storage and transfer issues as quickly as possible would be greatly appreciated.
