This driver provides the following functions:

SET CONFIGURATION
BYTE temperature_set_config (BYTE config)
Returns 1 if configuration was set sucessfully, 0 if not
config:
OS/ALERT | R1 | R0 | F1 | F0 | POL | TM | 1=Shutdown

R1:0 Resolution Convertsion Time (typ)
00 9 Bits (0.5°C) 40ms
01 10 Bits (0.25°C) 80ms
10 11 Bits (0.125°C) 160ms
11 12 Bits (0.0625°C) 320ms

READ TEMPERATURE
BYTE read_temperature (SIGNED_WORD *temperature)
Returns 1 if temperature was read sucessfully, 0 if not
temperature:
Returned 12 bit temperature reading is x0.0625ºC (16 bits per 1ºC). 0×0000 = 0ºC

The Dallas Maxim DS1337 is a I2C serial bus real time clock.. It provides low power time keeping for embedded designs with two alarm output pins.

[product_section_start:product_info_include_free_driver_top_box]

[product_section_start:product_page_section_details.png]

This driver provides the following functions:

SET REAL TIME CLOCK TIME
BYTE rtc_set_time (BYTE alarms_enabled, BYTE hours, BYTE minutes, BYTE seconds, BYTE day, BYTE date, BYTE month, BYTE year)
The fields are converted from binary to BCD before being sent to the RTC
alarms_enabled 0 = alarms disabled, bit0 = alarm 1 enable, bit1 = alarm 2 enable, bit2 = alarms trigger INTA & INTB (0=both trigger INTA)
hours 0 – 23
minutes 0 – 59
seconds 0 – 59
day 1 – 7
date 1 – 31
month 1 – 12
year 0 – 99

GET REAL TIME CLOCK TIME
BYTE rtc_get_time (BYTE *hours, BYTE *minutes, BYTE *seconds, BYTE *day, BYTE *date, BYTE *month, BYTE *year)
All fields are converted to binary values
hours 0 – 23
minutes 0 – 59
seconds 0 – 59
day 1 – 7
date 1 – 31
month 1 – 12
year 0 – 99

SET REAL TIME CLOCK ALARM
BYTE rtc_set_alarm (BYTE alarm_id, BYTE alarms_enabled, BYTE hours, BYTE minutes, BYTE seconds, BYTE date_day)
The fields are converted from binary to BCD before being sent to the RTC
alarm_id 1 – 2
alarms_enabled 0 = alarms disabled, bit0 = alarm 1 enable, bit1 = alarm 2 enable, bit2 = alarms trigger INTA & INTB (0=both trigger INTA)
hours 0 – 23
minutes 0 – 59
seconds 0 – 59 (not available for alarm 2)
date_day 1 – 31 (dates) or 101 – 107 (days)
Set any value to 0xff to be ignored in the alarm comparison
Note: After an alarm is activated the INT pin will remain driven low until rtc_clear_alarms() is called

CLEAR REAL TIME CLOCK ALARMS
BYTE rtc_clear_alarms (void)
When an enabled alarm trips the alarm flags must be cleared using this function to reset the INT pin(s).
