Hello~all, I want to made a project about smart home. Please look at the following picture before looking my problems. In the circuit,it can send the audio signal and video signal which taking simple by AD to ST and then ST will send them out . In another way,DA DA will return the audio and video to analog signal after ST received digital.My question: Is there anyone do such a project like me ? Could you give me some advice ? For example, What kind of chip do I need in the AD/DA of video. I have used STMF103 and stmf407 to do some project. At present,I would like to use this chip--VS1003 to be the output .Is it suitable? Thank you in advance! Welcome to design it with me! Have a nice day~
