Dear friends,
I have a requirement to do MP3 player with USB support. That player shall accept files from usb memory drive. It needs grafic display and wifi to automatically get java web page updates.
I want to use a processor.
Maybe solar ;-)
I must not use a encoder-decoder pair. But can U use the uart with RF frequencies? I don't think that decreasing the baud rate can solve the problem it may NOT!
Anybody have tried this ? If so, please guide me in the right direction.
Thank You

Wow. That is quite a task.
I must not use a encoder-decoder pair. But can U use the uart with RF frequencies?
What "encoder-decoder" do you mean ? What does it "encode" and "decode" ?
If you want to use some sort of wireless transmission, you'll have to use appropriate transceiver hardware.
You can't just "hook up" an UART to an antenna and expect it to work "wirelessly".
"I want to use a processor."
Yes - you will most certainly need a processor of some sort!
"I must not use a encoder-decoder pair"
What do you mean by that?
You cannot play MP3 without decoding it - so you must at least have a decoder! Presumably, the files will be provided already encoded?
"But can U use the uart with RF frequencies?"
Certainly not.
However, there are plenty of devices that can be connected to a UART to transport its communications over an RF link; eg, see: 't think that decreasing the baud rate can solve the problem"
What problem?
"please guide me in the right direction"
You need to do a lot more groundwork first. Consider the essential elements of your system: 1. USB; 2. A File system; 3. MP3 decoding; 4. Audio output; 5. Display; 6. WiFi; 7. Java support; 8. Web support; etc, etc, etc,...
You need to do a lot more groundwork first.
I would dare to say that "if you (the OP) have to ask _this_ question, the required completion date for your project is hopefully at least two years in the future, because that's how long it's going to take you".
"Groundwork" doesn't even cover what the OP needs to do. He needs to do the stuff that actually enables him to do groundwork.
Consider the essential elements of your system: 1. USB;
... and not just a USB device, but a USB host or at least USB-to-go.
2. A File system; 3. MP3 decoding;
... and there may be some licensing issues here. The MP3 algorithm is not free.
etc, etc.
The description of the project sound like it'll take an experienced developer at least a couple of months.
