Need help regarding PCF8563

SHAILESH_7860 · May 6, 2018, 6:35am

Hey,
I have a code which is working in MSP430 with DS3231 on a PCB, Now i have changed the design instead of DS3231 i have used pcf8563 and running the same code but it’s not working. so i want to replace Ds3231 code with pcf8563.
Can anyone help me.
main code-

PCF8563 code
/* 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

For goodness sake why don't people read this before posting a programming question and follow the advice it contains

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

If the posting says the code is to long to put in code tags, attach it as an .ino file.

Thanks.. Tom...
