Hi,
I am trying to check lpc1857 USB host keyboard example on lpc1837 explorer board.
The code compiles and loads and when run it completes it's USB initialization with no errors. It then hangs waiting for the host to complete it's initialization and getting continuously usbDeviceError.
Please point working USB Host example code for LPC1837.
How can i use the existing code on LPC1837 explorer board?
Thanks
vinod
Hi,
Is there any update on this?
Hi Bernhard,
There are no setup issues as we verified LPCOpen host keyboard example on NGX Xplorer board.
Hence please provide USB CMSIS driver and Keil middleware based example for LPC1837 device to run on NGX Xplorer board which is missing in your LPC1800 DFP demo examples.
We have already tried to run USB Host keyboard demo example of LPC1857 device given in LPC1800 DFP on NGX Xplorer board but it is not working.
Thanks
Vinod
Hi Vinod,
as a first step, please try it with a different cable, maybe a shorter one.
Errors at this stage are normally based on a bad electrical signal quality.

Bernhard.
