C++ (Cpp) USBH_HID_GetASCIICode Example

Introduction

The c++ (cpp) usbh_hid_getasciicode example is extracted from the most popular open source projects, you can refer to the following example for usage.

Programming language: C++ (Cpp)

Method/Function: USBH_HID_GetASCIICode

Example#1

/**
  * @brief  Main routine for Keyboard application
  * @param  phost: Host handle
  * @retval None
  */
static void USBH_KeybdDemo(USBH_HandleTypeDef *phost)
{
    HID_KEYBD_Info_TypeDef *k_pinfo;
    char c;
    k_pinfo = USBH_HID_GetKeybdInfo(phost);

    if(k_pinfo != NULL)
    {
        c = USBH_HID_GetASCIICode(k_pinfo);
        if(c != 0)
        {
            USR_KEYBRD_ProcessData(c);
        }
    }
}
