USB device driver / LPC board

Started by ashu September 16, 2009

I have a LPC2478 board (http://www.embeddedartists.com/products/kits/
lpc2478_kit.php) which comes with a USB OTG port.

 I will run linux on this board and connect this to PC which runs
windowsXP  via USB OTG port.

I wanted to know if there is any quick way of making this USB
communication possible without writing a USB driver from scratch. Some
ready made USB API or some software like that which can reduce my
development time.



Regards

As far as I'm aware the LPC2478 does not have an MMU so chances of running Linux on it are approaching zero. -- Regards, Richard. + http://www.FreeRTOS.org Designed for Microcontrollers.

Does uClinux count ?? olimex has uClinux on their CD, and a link for uClinux patch on their web site. http://www.olimex.com/dev/lpc-2478stk.html don

my main problem is on the pc side and development of s/w on the pc side so that I communicate with the board via USB. I dont want to write a driver from scratch since that will take more time.

That depends on what you want to do with the USB. If you want a standard serial type communication then you can look at something like a CDC class driver. You can find a little information on this here: http://www.freertos.org/LPC1768_CrossWorks.html look under the "Functionality" section (it is for a different processor, but it may be compatible as it is also an LPC device). Also take a look at http://sourceforge.net/projects/lpcusb/ -- Regards, Richard. + http://www.FreeRTOS.org Designed for Microcontrollers.

Look at "gadget" which is a set of device-side drivers for functions such as serial over USB, "ethernet" over USB, mass storage over USB, etc, _AND_ corresponding host drivers for windows and linux PC's to talk to your device. Most embedded linux/uClinux devices with device-side USB "gadget", or else something along similar lines.
