Ok, I am trying to figure out this very simple procedure. I have a 16F876A interfaced via SPI to ISD17120 voice recorder chip. just to make this simple and get an idea i want to record 5 one second messages to the device. then I want to play those 5 messages randomly. if you look at the design guide follow the SPI command interface and these commands SET_PLAY SET_REC SET_ERASE. I am not fully understanding how to address the individual messages. if someone can give me some kind of clue as what to send to the ISD device that would be great. I have searched the forums please dont send me links to other projects involving different ISD devices unless its the 1700 series and pertains to my exact request.
