Single-Chip Voice Recording & Playback Device 60-Second Duration

Dec 242: Input port and input output port declaration in top module 2. Why this happens in my case? This pin indicates that the device is currently busy per- forming internal functions and can neither record nor play- back at the current time. So if am not giving any input signal the speaker out should be zero and during the ON it should varying nature,please correct me if I am wrong.

When I datsheet connecting the IC to supply the busy LED turns ON and from the datasheet what that signifies is the device is currently busy performing internal functions and can neither record nor playback at the current time. Hierarchical block is unconnected 3. Originally Posted by Akhil Mohan.

Refer to table X for a list of resistors and their resultant sampling rates. APR voice recorder problem I have done that already, but not hearing any beep sound when there is a high to low transition on pin1.


Is am making my point in a confusing manner, any way I am sorry If I am doing that: APR voice recorder problem Instead of a stero jack i prefer you to use a datashet mic available in the market Thanks so much for the advice. APR voice recorder problem dear sir, there is not any stop button in 8 message random access mode. But when I am giving a high to low transition on pin1, am not hearing the beep sound datashet BE is kept high.

A low edge on this pin plays or records the next message.

Turn on power triac – proposed circuit analysis 0. According to the datasheet description, one can neither perform recording or playback at that time.

This pin forces a jump to message 3 for either recording or playback. The diaphragm movement is not good datashest to some dc components uf is there, still!!! What is the function of TR1 in this circuit 3. If I am using 8lines it acts as input line and then why that connection is datasehet APR voice recorder problem Will try and let you know de results: Equating complex number interms of the other 6.

How reliable is it?
