带有媒体键的USB HID键盘位于18F2553上

寻找一些帮助获得报告ID到我的USB HID键盘的目的是添加媒体密钥。我一定会更新这个帖子，当我的问题已经解决。对不起，这有点长，但我想证明我已经尝试了很多东西。从MLA 2017 03-06开始。在修正FixDead地址后，可以（最后）发送键盘键到记事本。好的。现在，我想通过添加另一个TLD并引入报告ID来发送媒体控制键。这使我的描述符如下：我已经添加到KiBooDr.IpPuthRePosits中，然后我不确定是否应该改变：OR，并且我有SEtiN MyAppHykey BoBOARD任务，如果（HIDTXHANDLL繁忙…代码。但是，据我所知，键盘消息现在是9字节，限制为8字节，因此较低级别需要将其拆分为两个消息。我已经做了很多谷歌，Requneo和帖子从其他人，到目前为止，什么也没有。目前，它似乎无法适当地枚举。我还尝试修改原来的示例——删除保留字节并将报告ID添加到KEYBOADARIN PUTPUX报表的开始处，更新描述符如下：然后枚举，但不发送按键。

    Looking for some help getting report IDs into my USB HID keyboard with the aim of adding media keys.  I will be sure to update this post when the issue I am having is resolved.  Sorry, it's a bit long but I wanted to show that I've tried a lot of things.

Started with MLA 2017-03-06.  After correcting
fixed_address_descriptor.h
#define KEYBOARD_INPUT_REPORT_DATA_BUFFER_ADDRESS_TAG @0x500

#define KEYBOARD_OUTPUT_REPORT_DATA_BUFFER_ADDRESS_TAG @0x508

I can (finally) send keyboard keys to notepad.  Good.

Now, what I want is to send media control keys by adding another TLD and introduce report IDs.

This leaves my descriptor as follows:

//Class specific descriptor - HID Keyboard + media (size 100))
const struct{uint8_t report[HID_RPT01_SIZE];}hid_rpt01={
{ 0x05, 0x01, // USAGE_PAGE (Generic Desktop)
    0x09, 0x06, // USAGE (Keyboard)
    0xa1, 0x01, // COLLECTION (Application)
    0x85, 0x01, // Report ID
    0x05, 0x07, // USAGE_PAGE (Keyboard)
    0x19, 0xe0, // USAGE_MINIMUM (Keyboard LeftControl)
    0x29, 0xe7, // USAGE_MAXIMUM (Keyboard Right GUI)
    0x15, 0x00, // LOGICAL_MINIMUM (0)
    0x25, 0x01, // LOGICAL_MAXIMUM (1)
    0x75, 0x01, // REPORT_SIZE (1)
    0x95, 0x08, // REPORT_COUNT (8)
    0x81, 0x02, // INPUT (Data,Var,Abs)
    0x95, 0x01, // REPORT_COUNT (1)
    0x75, 0x08, // REPORT_SIZE (8)
    0x81, 0x03, // INPUT (Cnst,Var,Abs)
    0x95, 0x05, // REPORT_COUNT (5)
    0x75, 0x01, // REPORT_SIZE (1)
    0x05, 0x08, // USAGE_PAGE (LEDs)
    0x19, 0x01, // USAGE_MINIMUM (Num Lock)
    0x29, 0x05, // USAGE_MAXIMUM (Kana)
    0x91, 0x02, // OUTPUT (Data,Var,Abs)
    0x95, 0x01, // REPORT_COUNT (1)
    0x75, 0x03, // REPORT_SIZE (3)
    0x91, 0x03, // OUTPUT (Cnst,Var,Abs)
    0x95, 0x06, // REPORT_COUNT (6)
    0x75, 0x08, // REPORT_SIZE (8)
    0x15, 0x00, // LOGICAL_MINIMUM (0)
    0x25, 0x65, // LOGICAL_MAXIMUM (101)
    0x05, 0x07, // USAGE_PAGE (Keyboard)
    0x19, 0x00, // USAGE_MINIMUM (Reserved (no event indicated))
    0x29, 0x65, // USAGE_MAXIMUM (Keyboard Application)
    0x81, 0x00, // INPUT (Data,Ary,Abs)
    0xc0, // End Collection

    0x05, 0x0C, //* Usage Page (Consumer Devices)
    0x09, 0x01, //* Usage (Consumer Control)
    0xA1, 0x01, //* Collection (Application)
    0x85, 0x02, //* Report ID=2
    0x05, 0x0C, //* Usage Page (Consumer Devices)
    0x15, 0x00, //* Logical Minimum (0)
    0x25, 0x01, //* Logical Maximum (1)
    0x75, 0x01, //* Report Size (1)
    0x95, 0x07, //* Report Count (7)
        
    0x09, 0xe2, // USAGE (Mute) 0x01
    0x09, 0xe9, // USAGE (Volume Up) 0x02
    0x09, 0xea, // USAGE (Volume Down) 0x03
    0x09, 0xcd, // USAGE (Play/Pause) 0x04
    0x09, 0xb7, // USAGE (Stop) 0x05
    0x09, 0xb6, // USAGE (Scan Previous Track) 0x06
    0x09, 0xb5, // USAGE (Scan Next Track) 0x07
    0x81, 0x03, // INPUT (Cnst,Var,Abs) padding, 1 bit
    0xC0} /// End Collection
};

I have added   
    uint8_t reportId;
into     KEYBOARD_INPUT_REPORT

Then I changed
#define HID_RPT01_SIZE          100

Not sure if I should be changing: #define HID_INT_IN_EP_SIZE      8 or

/* Endpoint Descriptor */
0x07,/*sizeof(USB_EP_DSC)*/
USB_DESCRIPTOR_ENDPOINT, //Endpoint Descriptor
HID_EP | _EP_IN, //EndpointAddress
_INTERRUPT, //Attributes
DESC_CONFIG_WORD(8), //size
0x01,

And I have set
inputReport.reportId = 1;
in my APP_KeyboardTasks, if(HIDTxHandleBusy... code.

But as far as I can tell the keyboard message is now 9 bytes, with a limit of 8 bytes so the lower level needs to split it into two messages.  I've done a lot of googling, read Tsuneo and posts from others and so far nothing.  Currently it appears to fail to enumerate properly.

I've also tried just modifying the original example - removing the reserved byte and adding the report id into the start of KEYBOARD_INPUT_REPORT, updating the descriptor as follows:


//Class specific descriptor - HID Keyboard with consumer media keyboard
const struct{uint8_t report[HID_RPT01_SIZE];}hid_rpt01={
{ 0x05, 0x01, // USAGE_PAGE (Generic Desktop)
0x09, 0x06, // USAGE (Keyboard)
0xa1, 0x01, // COLLECTION (Application)
0xa1, 0x00, // collection physical
0x85, 0x01, // Report ID
0x05, 0x07, // USAGE_PAGE (Keyboard)
0x19, 0xe0, // USAGE_MINIMUM (Keyboard LeftControl)
0x29, 0xe7, // USAGE_MAXIMUM (Keyboard Right GUI)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x25, 0x01, // LOGICAL_MAXIMUM (1)
0x75, 0x01, // REPORT_SIZE (1)
0x95, 0x08, // REPORT_COUNT (8)
0x81, 0x02, // INPUT (Data,Var,Abs)
//0x95, 0x01, // REPORT_COUNT (1)
//0x75, 0x08, // REPORT_SIZE (8)
//0x81, 0x03, // INPUT (Cnst,Var,Abs)
0x95, 0x05, // REPORT_COUNT (5)
0x75, 0x01, // REPORT_SIZE (1)
0x05, 0x08, // USAGE_PAGE (LEDs)
0x19, 0x01, // USAGE_MINIMUM (Num Lock)
0x29, 0x05, // USAGE_MAXIMUM (Kana)
0x91, 0x02, // OUTPUT (Data,Var,Abs)
0x95, 0x01, // REPORT_COUNT (1)
0x75, 0x03, // REPORT_SIZE (3)
0x91, 0x03, // OUTPUT (Cnst,Var,Abs)
0x95, 0x06, // REPORT_COUNT (6)
0x75, 0x08, // REPORT_SIZE (8)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x25, 0x65, // LOGICAL_MAXIMUM (101)
0x05, 0x07, // USAGE_PAGE (Keyboard)
0x19, 0x00, // USAGE_MINIMUM (Reserved (no event indicated))
0x29, 0x65, // USAGE_MAXIMUM (Keyboard Application)
0x81, 0x00, // INPUT (Data,Ary,Abs)
0xc0, //end phy
0xc0} // End Collection
};



Then it enumerates but won't send keypresses.
