Drivers are accesses the same way as in Linux - using "/dev/xxx" entries and open/read/write API.

API

int open(const char *path, int flags)
int close(int fd)
int write(int fd, const void *buf, size_t size)
int read(int fd, void *buf, size_t size)
int lseek(int fd, int offset, int whence)

Common entries

Spi entries: /dev/spiX
Usart entries: /dev/usartX
Flash entries: /dev/mtdX
i2c entries: /dev/i2cX
