ISD1760 voice playback module

Using Arduino Project Guidance
#1

Hie, I’m looking for ideas, I have a voice module an ISD1760 driven by arduino uno. My problem is that I would like to trigger a specific message (among 5 messages previously recorded manually on the ISD) via a specific event of the arduino

Ex: if x < 4
( play a specific message)

Someone can enlighten me because I am pretty weak in prog syntax to access and read messages that are somewhere !!! in the memory of the ISD1760 .

Have you had a chance to look through the chip datasheet or used Google to search for example Arduino code?

#3

I have the datasheet and i have been going through it, you need to specify the set_record start and end address for you to be able to set_play from that address, but im very new to this im not sure how to go about that

There is code to play from current pointer on this forum but it doesn’t specify how to then play from a specific memory location

Please edit your post to add code tags.

#5

Need to invoke set_play so i direct playback to a specific memory address on the chip

#6

Done

Nope.

The code should look like this
