vendor_id : 0x8086 device_id : 0x1532 的芯片型号具体分析每一个参数
时间: 2024-05-17 18:14:07 浏览: 17
当我们使用PCI(Peripheral Component Interconnect)总线时,每个设备都有一个唯一的ID,由厂商ID(vendor ID)和设备ID(device ID)组成。
在这个例子中,vendor_id是0x8086,它代表的是Intel公司的唯一标识符,而device_id是0x1532,它代表的是这个芯片的设备ID。
芯片型号是基于vendor_id和device_id来确定的,它的名称是Intel 8 Series/C220 Series Chipset Family SATA AHCI Controller。这个型号包含了芯片的系列(8 Series/C220 Series Chipset Family)、功能(SATA AHCI Controller)以及厂商(Intel)。

写一个这个代码的调用实例:int WINAPI Sys_Open(HID_DEVICE *device, DWORD index, WORD vid, WORD pid);
以下是一个调用实例:
```
HID_DEVICE device;
DWORD index = 0;
WORD vid = 0x1234; // Vendor ID
WORD pid = 0x5678; // Product ID
int result = Sys_Open(&device, index, vid, pid);
if (result != HID_DEVICE_SUCCESS) {
printf("Failed to open HID device (error code: %d)\n", result);
return 1;
}
// Do something with the opened HID device...
Sys_Close(device); // Close the HID device
```
该调用实例会尝试打开一个 Vendor ID 为 0x1234,Product ID 为 0x5678 的 HID 设备,并返回一个 HID_DEVICE 结构体,表示设备已成功打开。如果打开失败,则会输出错误信息并返回错误代码。最后,使用 Sys_Close() 函数关闭设备连接。

这段log信息是一段系统启动时的输出信息,其中包括了ISP设备和外设的初始化过程。可以看到,系统首先完成了DDR内存的初始化和检测,然后开始初始化所有的ISP设备和外设。在这个过程中,系统还会输出一些调试信息,例如当前的DDR内存频率和供电电压等。这些信息可以帮助系统管理员进行故障排查和调试。如果您遇到了系统启动故障或者ISP设备和外设无法正常工作的问题,这些信息可能会对您有所帮助。
