/* Demonstration of Rtc_Pcf8563 Clock on LCD.
|
||||
*
|
||||
* 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
|
||||
*
|
||||
* This sketch connects a lcd to display 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
|
||||
* 1x h44780 LCD
|
||||
