Eric,

Seems you forgot to clear the R/W line so you cannot write other commands into LCD. First command is executed because R/W line cleared by C operator LCD_PORT=0x20.

Put the instruction CLR _LCD_RW in the beginning of the LCD_WRCMD routine body.

Besides I have to note there is no assignment of the _LCD_BUSY in your program.

Regards,

George

By the way, do you solve the problem of MP3 decoding?
