is PC needed for PIC controller to interface USB
Hi
I am working on a project in which i dont want PC support.
I want to know that does the PIC18F4550 needs PC after it had the firmware installed in it ??
If want to attach the USB Flash drive to it does it work ?????
Is there any way i can get USB interface by which i can attach my USB flash drive and work on that ?????
Regards
Manish

Manish,
The CUI32 is based on the PIC32MX440F512 with StickOS loaded initially. This allows software development with
only a terminal with USB out adapter, and no programmer needed. I think I read that StickOS/PIC32MX440 supports
USB host mode, but how would you get your code into the flash drive? More details may get you some better and more
complete answers.

StickOS indeed supports USB Host Mode on the PIC332MX4. When USB Host Mode is enabled, all BASIC "print" statements are appended to the file stickos.log on the USB flash drive, so you can make an easy data logger that way.
To program the CUI32 when USB Host Mode is enabled, in general you'll want to use the UART console interface rather than the USB console interface. To use the UART console interface you need an RS-232 level shifter (such as http://www.sparkfun.com/commerce/product_info.php?products_id=133) connected to PIC32 UART2 pins rf4 and rf5, configured for 9600 baud, 8 data bits, and no parity. Then you can use a terminal emulator connected to the RS-232 interface.
