![]() The new MMC/SD card driver supports MMC, SD (SDSC) and SDHC cards and it has the name mmcsd_m.c and it can be downloaded from the link below:įAT (FAT16 and FAT32) library for CCS C compiler download: MMC/SD card driver for CCS C compiler download: *** For microcontrollers with limited RAM and ROM there is another FAT library for reading files from SD cards, it supports FAT16 and FAT32 at the same time and works with MMC, SD and SDHC cards: The other library which is the FAT library also does not support even medium size cards (for example 2GB SD card). But unfortunately the MMC/SD card driver has some small bugs (if I can say that) and does not support most of the MMC/SD cards available on the market today including SD and SDHC cards. This compiler comes with many drivers and libraries, two of them are MMC/SD card driver (file: mmcsd.c ) and FAT library (file: fat.c ), the FAT library supports FAT16 and FAT32 file systems where the user has to choose between them (not both at the same time), hence the RAM usage is lower. ![]() ![]() The CCS C compiler is one of the best Microchip PIC® compilers especially when we talk about code optimization.
