Dayz Posted December 12, 2006 Report Share Posted December 12, 2006 Hello,I would like to know if its possible to use a 8051 microcontroller to design a simple mp3 player. My microcontroller is 40Mhz and I would like it to read data from a USB or SD card. Is this possible? Does anyone have any good sites for usb protocal? Thank You Quote Link to comment Share on other sites More sharing options...
farhatdude Posted December 16, 2006 Report Share Posted December 16, 2006 USB interface itself is a project, I once developed an interface with regular hard disk drive and USB using 8051. I can provide you with assistance about that project, but ain't sure that might work out for you in this mp3 read. Quote Link to comment Share on other sites More sharing options...
Dayz Posted December 16, 2006 Author Report Share Posted December 16, 2006 Yes, I spoke with my professor and She said this would be really hard since the USB Protcal is very complicated. Quote Link to comment Share on other sites More sharing options...
Fowkc Posted December 17, 2006 Report Share Posted December 17, 2006 There are interfaces for microcontrollers (via SPI, I2C) that will allow communication to/from USB devices or memory cards, but I'm not sure if they'll cope with the data rate needed to play MP3s.
