BLE遥控

1/ 配对

2、开机广播

3、按键扫描

4、键值映射

修改keycodeMap 为自定义按键的键值。

   static CONST keycodeMap_t keycodeMap[12] =
{
// 0b00 <KPb> <KPa>
// row mapped    to P0 and P1
// column mapped to shift register controlled by P0 and P2
{ HID_KEYBPAD_MENU, USAGE_PAGE_GD },                       // 0b00 10 1101   - 9
{ HID_KEYBOARD_HOME, USAGE_PAGE_GD },                       // 0b00 10 1110   - 6
{ 0x66, USAGE_PAGE_GD },                 // 0b00 10 1111
{ 0xf1, USAGE_PAGE_GD },
{HID_KEYBOARD_RETURN,USAGE_PAGE_GD },
{HID_KEYBOARD_UP_ARROW,USAGE_PAGE_GD},
{HID_KEYBOARD_RIGHT_ARROW,USAGE_PAGE_GD},
{HID_KEYBOARD_LEFT_ARROW,USAGE_PAGE_GD},
{HID_KEYBOARD_DOWN_ARROW,USAGE_PAGE_GD},
{ HID_KEYBOARD_VOLUME_DOWN, USAGE_PAGE_GD },
{ HID_KEYBOARD_VOLUME_UP, USAGE_PAGE_GD },
{ HID_KEYBOARD_RESERVED, USAGE_PAGE_GD },              // 0b00 10 1111
};

5、键值范围

Hidkbmservice.c (projects\ble\profiles\hiddevkbm)

static CONST uint8 hidReportMap[] =
{

0x05, 0x01, // Usage Page (Generic Desktop)
0x09, 0x02, // Usage (Mouse)
0xA1, 0x01, // Collection (Application)

。。。。。。

}

               //   Key arrays (6 bytes)
0x95, 0x06, //   Report Count (6)
0x75, 0x08, //   Report Size (8)
0x15, 0x00, //   Log Min (0)
0x25, 0x65, //   Log Max (101)
0x05, 0x07, //   Usage Pg (Key Codes)
0x19, 0x00, //   Usage Min (0)
0x29, 0xff, // 0x65, //   Usage Max (101)

0x25, 0x65, // Log Max (101)

0x29, 0x65, // Usage Max (101)------------------> 0x29 ~0xff 的键值范围。

这两组值都要修改成 0xff 就好。

6 、睡眠功耗
