/* Demonstration of Rtc_Pcf8563 Set Time.
|
||
|
|
* Set the clock to a time then loop over reading time and
|
||
|
|
* output the time and date to the serial console.
|
||
|
|
*
|
||
|
|
* I used a RBBB with Arduino IDE, the pins are mapped a
|
||
|
|
* bit differently. Change for your hw
|
||
|
|
* SCK - A5, SDA - A4, INT - D3/INT1
|
||
|
|
*
|
||
|
|
* After loading and starting the sketch, use the serial monitor
|
||
|
|
* to see the clock output.
|
||
|
|
*
|
||
|
|
* setup: see Pcf8563 data sheet.
|
||
|
|
* 1x 10Kohm pullup on Pin3 INT
|
||
|
|
* No pullups on Pin5 or Pin6 (I2C internals used)
|
||
|
|
* 1x 0.1pf on power
|
||
|
|
* 1x 32khz chrystal
|
