Hi,

If you already have some project for DE2-115, just dowload this project for DE-1 http://www.emb4fun.de/fpga/fatfs/download/fatfs_de1_sw_spi_20130811.zip , then copy hw\ip\pio_spi folder in your IP Cores directory, then copy sources from \sw\de1_fatfs_sw_spi to your software project. You may to open project for DE-1 to learn how make IP core instance in QSYS and software organization.

Or the other way, just open project for DE-1, replace top level file and pins assigment, change target device, recompile QSYS and Quartus project, and try to run it.

Best Regards
