I am successfully using USBHost library with my Due and a standard USB keyboard, the problem comes about when I try to use a numeric USB keyboard.
The problem is the numeric keyboard returns a different OemKey value to the numbers on the standard key board, and this OemKey value has not been mapped within the library.
I have never attempted playing with a library before. and rather hoped simply adding the new values would solver the issue....it didnt
Can anyone advise if I am on the right track or point me in the right direction please.
The values returned and keys are as follow, along with the library.
Thanks in advance
Actual Key pressed GetOemKey response
1 = 89,
2 = 90,
3 = 91,
4 = 92,
5 = 93,
6 = 94,
7 = 95,
8 = 96,
9 = 97,
0 = 98
