Hi,

I am new in this area. I need to interface lpc1769 with usb mass storage device (pendrive) , HID(mouse and keyboard).
I could not get any sample code on lpc site .Where can I find it.

The mbed device is based on an LPC1768. The libraries at mbed.org seem to support what you are looking for.

Unfortunately, I don't know what you can get if you are not a registered user and to get registered, you need to buy an mbed device.

Nevertheless, what you want to do can be done.

Thank you Rechard !!

I am working with LPCXpresso board with LPC-link .

I could not get sample code for USB HID on lpc1769 .

I don't know much about USB communication so again can not modify the code given for lpc1768 .

Can I please know where do we need modifications in these codes .

Thank you

AFAIK, the only difference between the 1768 and the 1769 is maximum clock rate. The 1768 is supposed to be limited to 100 MHz and the 1769 to 120 MHz. Internally, AFAIK, they are the same.

Check the datasheet.
