編輯：見下文的Arduino：更改定義無編輯庫[解決，錯誤在編譯器，提供解決方法]
我的回答我是相當新到Arduino平臺，創造一個現在USB HID項目與AdaFruit的attiny85（Trinket）庫。另請參閱我以前回答關於此庫的選項的問題： Change/Override Trinket (attiny85) USB identification name, device name
我很難理解一個罕見的C相關限制（請參閱上一個問題上面的鏈接中的最新評論），分離的後期綁定二進制文件通過分離編譯。如果你想改變USB設備的選項，你必須改變庫本身，對我來說有點奇怪，因爲它是一個庫。例如，如果在加載庫之前包含帶有更改選項的頭文件，則不會更改任何內容，因爲庫未知，因爲它必須包含在此庫中。
示例：這不工作：
#include "myUSBOptions.h"
#include "TrinketHidCombo.h"
另一種方法：
所以我需要改變庫本身對每一個項目，在這種情況下，usbconfig.h文件。這對我來說聽起來很愚蠢，因爲它是一個圖書館，可以被其他項目使用。 也許這是Adafruit圖書館中的一個設計錯誤，像vendorname，devicename等這樣的東西必須是可選的，並且在庫的更新時您的設置可以被覆蓋。而且...您需要爲每個分離的項目再次編輯文件。
所以我想出了在usbconfig.h文件中包含一個可選頭文件#include "user_usbconfig.h"這個想法只需要一個改變。但這不是唯一的usbconfig.h文件，至少有三個版本可用！在項目目錄中創建一個user_usbconfig.h文件，寫一個批處理文件以將其自動化並將其包含在項目目錄中，以便在切換項目時只需單擊它即可更改選項。
線加入usbconfig.h文件：包含在項目
/* DEVICE SETTINGS */
/* Version number of the device: Minor number first, then major number. */
#define USB_CFG_DEVICE_VERSION 0x00, 0x01
/* VENDOR_NAME
* These two values define the vendor name returned by the USB device. The name
* must be given as a list of characters under single quotes. The characters
* are interpreted as Unicode (UTF-16) entities.
* If you don't want a vendor name string, undefine these macros.
* ALWAYS define a vendor name containing your Internet domain name if you use
* obdev's free shared VID/PID pair. See the file USB-IDs-for-free.txt for
* details.
*/
#define USB_CFG_VENDOR_NAME 'm', 'y', 'C', 'o', 'm', 'p', 'a', 'n', 'y', 'n'
#define USB_CFG_VENDOR_NAME_LEN 10
/* DEVICE_NAME
* Same as above for the device name. If you don't want a device name, undefine
* the macros. See the file USB-IDs-for-free.txt before you assign a name if
* you use a shared VID/PID.
*/
#define USB_CFG_DEVICE_NAME 'm', 'y', 'D', 'e', 'v', 'i', 'c', 'e'
#define USB_CFG_DEVICE_NAME_LEN 8
/* SERIAL_NUMBER
* Same as above for the serial number. If you don't want a serial number,
* undefine the macros.
* It may be useful to provide the serial number through other means than at
* compile time. See the section about descriptor properties below for how
* to fine tune control over USB descriptors such as the string descriptor
* for the serial number.
*/
/*#define USB_CFG_SERIAL_NUMBER 'N', 'o', 'n', 'e' */
/*#define USB_CFG_SERIAL_NUMBER_LEN 0 */
例源碼myProject的
.......
#include "cmdline_defs.h"
#ifndef __usbconfig_h_included__
#define __usbconfig_h_included__
#include "user_usbconfig.h" // <-- added this
.......
例如user_usbconfig.h。井野，什麼也不做，除了激活USB：
#include "TrinketHidCombo.h"
void setup()
{
TrinketHidCombo.begin();
}
void loop() // Main program - main()
{
// do nothing, check if USB needs anything done
TrinketHidCombo.poll();
}
批處理文件創建，加入項目目錄：

結論和問題：
雖然這種方法工作正常，我仍然不滿意，並想知道是否有更簡單的方法，而不需要更改庫的任何代碼行。一個更「實時」的解決方案，所以你不必考慮這一點，以避免錯誤和其他令人頭痛的問題。
你已經超出了Arduino庫。考慮在較低的槓桿工作。 –
