Driver API

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
