Each file object (FFOBJID, FIL, DIR) contains a 512 byte buffer cache for file operations. By setting FF_FS_TINY to 1 in ffconf.h this buffer is removed and a global buffer is used. This will make the FatFS file IO a bit easier on memory for user apps.

Acceptance Criteria:

• The code is not significantly slower after the change
• No other issues are reported

Benchmarking:

The BASIC file benchm9,bas will run a read/write operation. Base timings before the mod are:

• Write: 29.85s
• Read: 14.2s
