USB HID Keyboard Device (usb_dev_keyboard)

+//! +//! This example application turns the evaluation board into a USB keyboard +//! supporting the Human Interface Device class. When the push button is +//! pressed, a sequence of key presses is simulated to type a string. Care +//! should be taken to ensure that the active window can safely receive the +//! text; enter is not pressed at any point so no actions are attempted by the +//! host if a terminal window is used (for example). The status LED is used to +//! indicate the current Caps Lock state and is updated in response to any +//! other keyboard attached to the same USB host system. +//! +//! The device implemented by this application also supports USB remote wakeup +//! allowing it to request the host to reactivate a suspended bus. If the bus +//! is suspended (as indicated on the application display), pressing the +//! push button will request a remote wakeup assuming the host has not +//! specifically disabled such requests. +//! +// +//***************************************************************************** + +//***************************************************************************** +// +// The system tick timer period. +// +//***************************************************************************** +#define SYSTICKS_PER_SECOND 100 + +//***************************************************************************** +// +// A mapping from the ASCII value received from the UART to the corresponding +// USB HID usage code. +// +//***************************************************************************** +static const int8_t g_ppi8KeyUsageCodes[][2] = +{ + { 0, HID_KEYB_USAGE_SPACE }, // 0x20 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_1 }, // ! 0x21 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_FQUOTE }, // " 0x22 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_3 }, // # 0x23 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_4 }, // $ 0x24 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_5 }, // % 0x25 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_7 }, // & 0x26 + { 0, HID_KEYB_USAGE_FQUOTE }, // ' 0x27 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_9 }, // ( 0x28 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_0 }, // ) 0x29 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_8 }, // * 0x2a + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_EQUAL }, // + 0x2b + { 0, HID_KEYB_USAGE_COMMA }, // , 0x2c + { 0, HID_KEYB_USAGE_MINUS }, // - 0x2d + { 0, HID_KEYB_USAGE_PERIOD }, // . 0x2e + { 0, HID_KEYB_USAGE_FSLASH }, // / 0x2f + { 0, HID_KEYB_USAGE_0 }, // 0 0x30 + { 0, HID_KEYB_USAGE_1 }, // 1 0x31 + { 0, HID_KEYB_USAGE_2 }, // 2 0x32 + { 0, HID_KEYB_USAGE_3 }, // 3 0x33 + { 0, HID_KEYB_USAGE_4 }, // 4 0x34 + { 0, HID_KEYB_USAGE_5 }, // 5 0x35 + { 0, HID_KEYB_USAGE_6 }, // 6 0x36 + { 0, HID_KEYB_USAGE_7 }, // 7 0x37 + { 0, HID_KEYB_USAGE_8 }, // 8 0x38 + { 0, HID_KEYB_USAGE_9 }, // 9 0x39 + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_SEMICOLON }, // : 0x3a + { 0, HID_KEYB_USAGE_SEMICOLON }, // ; 0x3b + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_COMMA }, // < 0x3c + { 0, HID_KEYB_USAGE_EQUAL }, // = 0x3d + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_PERIOD }, // > 0x3e + { HID_KEYB_LEFT_SHIFT, HID_KEYB_USAGE_FSLASH }, // ?
