Data Structures

Overview

Structs used by the driver.

Note

This is example show how to instantiate RTC with rtc_instance_t, rtc_api_t and rtc_data_t.

#define I2C_CTRL_HZ     SYSTEM_CLINT_HZ
#define I2C_CTRL        (i2c_hwreg_t *)SYSTEM_I2C_1_IO_CTRL
#define I2C_FREQ        100000
#define RTC_CTRL            RTC_DS3231_ADDR
#define RTC_DRIVER          ds3231_driver
 
rtc_instance_t RTC = {
    .drv  = &RTC_DRIVER,
    .inst = &(i2c_instance_t){
        .hwreg                  = I2C_CTRL,
        .slaveAddress           = RTC_CTRL,
        .samplingClockDivider   = 3,
        .timeout                = I2C_CTRL_HZ/1000,
        .tsuDat                 = I2C_CTRL_HZ/(I2C_FREQ*5),

        .tHigh                  = I2C_CTRL_HZ/(I2C_FREQ*2),
        .tBuf                   = I2C_CTRL_HZ/(I2C_FREQ),
},
};
 rtc_data_t t = RTC.current_time;
 printf("Current Time: %02d:%02d:%02d %s\n\n", t.hours, t.minutes,
             t.seconds, (t.PM) ? "PM" : "AM");
