Fork of SDFileSystemDMA by
SDFileSystemDMA is enhanced SDFileSystem library for STM32 micros by using DMA functionality.
Max read transfer rate reaches over 2MByte/sec at 24MHz SPI clock if enough read buffer size is set.
Even though minimum read buffer size (512Byte) is set, read transfer rate will reach over 1MByte/sec at 24MHz SPI Clock.
( but depends on the ability of each SD card)
Test program is here.
https://developer.mbed.org/users/mimi3/code/SDFileSystemDMA-test/
Supported SPI port is shown below table.
(v): Verified. It works well.
(w): Probably it will work well. (not tested)
(c): Only compiled. (not tested)
(f): Over flash.
(r): Only read mode. (when _FS_READONLY==1)
(u) Under construction
(z): Dose not work.
Caution
If your board has SRAM less than or equal to 8KB, the buffer size must be set to 512 Bytes.
