Hi, may i know how to connect flash drive to PIC microcontroller? Microcontroller that i using is PIC18F4520. The apllication that i want to do is use PIC microcontroller to play a music by connecting USB flash drive. Can i make it?

hi, i am not sure PIC18F4520 have or can act as USB HOST, maybe you can survey for PIC18F4550 or can search from this link. http://www.microchip.com/ParamChartSearch/chart.aspx?branchID=1005. To handle music file also challenging.

Hi tzyuen1122,

FYI, PIC18F4520 not support for USB host, and currently all 8-bit PIC (PIC16 & PIC18) don't support that feature.
You can consider to explore 16-bit PIC (PIC24 series) or 32-bit PIC for this application.

Thanks.

Thanks for reply. If connect PIC microcontoller with one chip, then communicate with I2C or SPI, so able to that?

Are you referring to USB pendrive? USB Pendrive is using USB to communicate, I2C or SPI will not help. But you are referring other chip, it will depends on that chip. If it is I2C, you will need to use I2C.
