Dear All,
I am about to make a small project using the features in AT89E51( in system programmable microcontroller ). My ideas are :
1. to record incoming phone call ( answering machine ) by feeding the analog audio output from a telephone to an ADC
2. Storage media will be a HDD ( i suppose 1,2GB will be enough )
3. LCD Display, will display how many message received , number ID...etc
4. capability to play back all recorder messages by selection
5. capability to erase message one by one
I wonder how to make a driver software for the HDD, and in what format will the voice data be saved ( wav or...)
Would be a great help if anybody can give me suggestion or gives me the relevant project description.Thank's
