Configuration of the USB Host HID Class in µVision.

Configuration of the USB Host HID Class in µVision.

HID Class Configuration File

The USB Host HID Class configuration file USBH_Config_HID.h contains the following settings:

• Number of concurrent HID Devices in system specifies the number of HID devices that will be supported.
• HID Interrupt In Pipe handling Thread Stack Size specifies the thread stack size for the thread that polls the interrupt endpoint of the HID.
• The default HID Interrupt In Pipe handling Thread priority is osPriorityAboveNormal. This priority can be changed by changing USBH_HID_INT_IN_THREAD_PRIORITY define in this configuration file. This priority needs to be high enough so that USB Stack can react to USB events in a timely manner. Due to this requirement it is recommended to keep this setting at default.
