Description
usb_host_android.h
void
Tasks function that keeps the Android client driver moving. Keeps the driver processing requests and handling events. This
function should be called periodically (the same frequency as USBHostTasks() would be helpful).
This function should be called periodically to keep the Android driver moving.
AndroidAppStart ( see page 24)() function has been called before the first calling of this function
void AndroidTasks(void)
usb_host_android.h
#define
Error code indicating that the buffer passed to the read function was too small. Since the USB host can't control how much
data it will receive in a single packet, the user must provide a buffer that is at least the size of the endpoint of the attached
device. If a buffer is passed in that is too small, the read will not start and this error is returned to the user.
