some 32bit uc have OTG module. but how to implement FAT on uc ?
I want to only read from pen drive not writting to pen drive.
plz guide me]]> Wed, 07 May 2008 19:56:59 -0700 http://www.8051projects.net/forum-t9363.html Re: microcontroller - pen drive interfacing http://www.8051projects.net/forum-t9363.html Fa32t library available online.. and can be ported to any AVR, PIC and ARM controller.

The problem you could face while using pendrive is, there is no direct interaction between File system or Flash memory of drive rather you have to go through USB interface of pen drive. So you might have to write drivers for generic mass storage device. I have least idea of the protocol used my mass storage devices. But there is one book in forum on USB mass storage applications. That could be of some help to you.]]> Ajay<contact@nospam.com> Thu, 08 May 2008 15:20:31 -0700 http://www.8051projects.net/forum-t9363.html Re: microcontroller - pen drive interfacing http://www.8051projects.net/forum-t9363.html Jivan<mail2jivan@nospam.com> Fri, 09 May 2008 13:59:39 -0700 http://www.8051projects.net/forum-t9363.html Re: microcontroller - pen drive interfacing http://www.8051projects.net/forum-t9363.html sashijoseph<sashijoseph@nospam.com> Fri, 09 May 2008 14:55:22 -0700 http://www.8051projects.net/forum-t9363.html Re: microcontroller - pen drive interfacing http://www.8051projects.net/forum-t9363.html

u are reading from pen drive...

that makes ur controller a host!!!!

make sure ur controller has the capability of being a usb host or else no use of writing a FAT32 algo! cause in "On The Go" mechanism a Host is required... that makes it clear that they cant be used as HOST!

hope u get my point

490 rs..

certainly it is a better bet considering the foollowing features..

8/32 bit V-MCU Core
* Dual DMA controllers for hardware acceleration
* 64k Embedded Flash Program Memory
* 4k internal Data SRAM
* 2 x USB 2.0 Slow/Full speed Host/Slave Ports
* UART, SPI and Parallel FIFO interfaces
* PS2 legacy Keyboard and Mouse Interfaces
* Up to 28 GPIO pins depending on configuration
* 3.3V operation with 5V safe inputs
* Low power operation (25mA running/2mA standby)
* Inbuilt FTDI firmware easily updated in the field
* LQFP-48 RoHS compliant package
* Multi-processor configuration capable



wud certainly like to know its availability in INDIA..

I will do the further study on this chip. also i will checkout the availibility in india.

thanks again.]]> Jivan<mail2jivan@nospam.com> Sun, 11 May 2008 14:22:29 -0700 http://www.8051projects.net/forum-t9363.html
