HI
i'm using lpx4357 and successfully completed keyboard interfacing using USB HID but when i connect a barcode scanner hard fault occurs after scanning .. only one byte read / detected and then it goes to hard fault.. can i get some ideas why this could be happen?? or any suggestions ?
please help!
Is your project based on lpcopen demo ? if yes which one? any revise ?
Please track where runs to error? Does it enumerate well?
Hi,
I am trying to interface the USB barcode scanner. I am using the LPCOpen Keyboard Host example, I am getting the keyboard keys. But when I connect the barcode scanner, it shows device is enumerated, but now able to read the barcode data. Can you please let me know, what modification need to be done in the keyboard code example to read the barcode data.
Controller LPC4337
Barcode Make Newland.
Model NLS-HR11
Warm regards.
