Detailed Description

Field Documentation

clock_offset

size_t i2c_rtc_base::clock_offset

Offset of the start of the clock register block.

hw_init

int(* i2c_rtc_base::hw_init) (struct i2c_rtc_base *ctx)

Hardware initialization function. Will be called once when the RTC is used for the first time. Can return 0 on success or anything else on error. In an error case, it will be called again on the next use.

i2c_addr

uint8_t i2c_rtc_base::i2c_addr

I2C address.

i2c_bus_path

const char* i2c_rtc_base::i2c_bus_path

The path of the I2C bus device.

initialized

bool i2c_rtc_base::initialized

Whether the RTC has already been initialized. Used internally.

mutex

rtems_mutex i2c_rtc_base::mutex

Just initialize with RTEMS_MUTEX_INITIALIZER('mcp7940').

struct { ... } i2c_rtc_base::order

Order of the fields of the date.
