stm32制作CAN适配器5--WinUsb上位机编写

上次我们要stm32制作了一个基于winusb有canfd适配器，今天我们来制作一个上位机程序来进行报文收发。
上位机还是用以前写好的，只是更改下dll文件。

项目链接器，输入，附加依赖项中增加winusb.lib
在这里插入图片描述

winusb初始化：

#include "zlgcan.h"#ifdef WIN32

HDEVINFO deviceInfoSet;

}

WinUsb读写

int winusb_write(WINUSB_INTERFACE_HANDLE winusbHandle,const BYTE* buffer,DWORD size)
{BOOL result = FALSE;ULONG byteswritten = 0;result = WinUsb_WritePipe(winusbHandle, EP0ADDR, (PUCHAR)buffer, size, &byteswritten, NULL);return byteswritten;
}int winusb_read(WINUSB_INTERFACE_HANDLE winusbHandle, BYTE* buffer, DWORD size)
{BOOL result = FALSE;DWORD bytesRead = 0;result = WinUsb_ReadPipe(winusbHandle, EP1ADDR, buffer, size, &bytesRead, NULL);return bytesRead;
}
