/**
* Brief:
* This test code shows how to configure gpio and how to use gpio interrupt.
*
* GPIO status:
* GPIO18: output
* GPIO19: output
* GPIO4: input, pulled up, interrupt from rising edge and falling edge
* GPIO5: input, pulled up, interrupt from rising edge.
*
* Test:
* Connect GPIO18 with GPIO4
* Connect GPIO19 with GPIO5
* Generate pulses on GPIO18/19, that triggers interrupt on GPIO4/5
*
* This example Implemented BLE HID device profile related functions, in which the HID device
* has 4 Reports (1 is mouse, 2 is keyboard and LED, 3 is Consumer Devices, 4 is Vendor devices).
* Users can choose different reports according to their own application scenarios.
* BLE HID profile inheritance and USB HID class.
