Hi,
I am an Electrical Engineer and an Embedded Systems expert. I have 2+ years of experience with Embedded Systems based on microcontrollers of ARM, PIC, AVR, Freescale, TI, 8051 and many more.
I have experience of interfacing SDcard with microcontrollers and have done so previously with ARM microcontrollers. Also I have done projects that involved playing MP3 and WAV files from SD Card. I can help you most in this part. I have both MikroC compiler with me as well as Proteus software.
I can provide you with a well documented schematic and a thoroughly commented code.
I will be looking forward to your response and working with you.
Regards
