Hello all,
first, I want to thank you. With your help I was able to quickly understand ISD1700 functionnality (really bad datasheet !!).

I made a system that can speak numerous messages: Not full messages are recorded, but words.
Then I compose my message, sending play for words one after other.

My question is: How to copy memory from one ISD to another ? Is there a digital way via SPI commands ? I don't want to record my voice on each ISD !!!
