hi tinnie, the ISD2560 on PR17 records and playback in the chip itself, you cannot obtain the voice recorded from it.
We need to make 2 things clear here. 1st, you want to control the button on PR17? If in that case, you have several ways to do it. hardware need to be ready, you can either use parallel port from computer to interface, or serial port. Develop the software using vb.net on computer and also the PIC microcontroller firmware if it is needed.
2nd, if you want to record the voice and playback using vb.net, you can actually wave the PR17, computer have all the interface with the audio input as mic and output as speaker. Develop the vb.net to record sound from mic and play it back through speaker.
Good luck!
