hi i have a device i am trying to make duplicate of and i have the good one that works fine and another that looks simular but conected does not want to work i was wondering how can i read code from the one that work and just copy on to the other it has ds 1302 realtime clock i was wondering if theres a program or software that will let me read and write etc any help would be great thank
 

Which mcu is used on your PCB with the DS1302?

If this is a commercial product, the software is probably protected from coping.

the one that i have the person that sold it to me wrote it i think and im trying to see how can i clone it

also the one that works has a crystal that reads on it E32K and the one that isnt working says on it KDS4A i dont kno if there both the same or not but i see that the 2 pins on crystal go to pin 6 n 7 on ds1302

Carlos, your request does not define the hardware, software, your limitations or interface equipment. The relevance to an RTC which has only volatile 31 bytes of static RAM and thus nothing to copy, adds to the mystery. Can you clarify your needs with background info, photos and ensure there is no Intellectual Property violation?

In short how can we help?

Thats the specs for tue E32k
Im wondering if i swap out the kds4a oscilator to a e32k will it work the same as the one that has the e32k oscilator

**broken link removed**

this is the pic of the oscilator of the one that is working fine the other has an oscilator that says kds4a
