CH32F205 兩個(gè)usb 一個(gè)配置為主機(jī) 一個(gè)配置為HID設(shè)備主機(jī)接收HID設(shè)備數(shù)據(jù) 然后通過從機(jī)USB端口轉(zhuǎn)發(fā)給PC?

這是主函數(shù)設(shè)置

int main( void )

{

? ? /* Initialize system configuration */

? ? Delay_Init( );

? ? USART_Printf_Init( 115200 );

? ? DUG_PRINTF( "SystemClk:%d\r\n", SystemCoreClock );

? ? DUG_PRINTF( "USB HOST KM Test\r\n" );

? ? /* Initialize TIM3 */

? ? TIM3_Init( 9, SystemCoreClock / 10000 - 1 );

? ? DUG_PRINTF( "TIM3 Init OK!\r\n" );

? ? /* Initialize USBHS host */

? ? /* Note: Only CH32F205/CH32F207 support USB high-speed port. */

#if DEF_USBHS_PORT_EN

? ? DUG_PRINTF( "USBHS Host Init\r\n" );

? ? USBHS_RCC_Init( );

? ? USBHS_Host_Init( ENABLE );

? ? memset( &RootHubDev[ DEF_USBHS_PORT_INDEX ].bStatus, 0, sizeof( ROOT_HUB_DEVICE ) );

? ? memset( &HostCtl[ DEF_USBHS_PORT_INDEX * DEF_ONE_USB_SUP_DEV_TOTAL ].InterfaceNum, 0, DEF_ONE_USB_SUP_DEV_TOTAL * sizeof( HOST_CTL ) );

#endif

? ? /* Initialize USBFS host */

#if DEF_USBFS_PORT_EN

? ? DUG_PRINTF( "USBFS Host Init\r\n" );

//? ? USBFS_RCC_Init( );

//? ? USBFS_Host_Init( ENABLE );

? ? USBFS_RCC_Init( );

???? USBFS_Device_Init( ENABLE );

???? DUG_PRINTF(" < - USB DEVCIE INIT OK - > \r\n");

? ? memset( &RootHubDev[ DEF_USBFS_PORT_INDEX ].bStatus, 0, sizeof( ROOT_HUB_DEVICE ) );

? ? memset( &HostCtl[ DEF_USBFS_PORT_INDEX * DEF_ONE_USB_SUP_DEV_TOTAL ].InterfaceNum, 0, DEF_ONE_USB_SUP_DEV_TOTAL * sizeof( HOST_CTL ) );

#endif

? ??

? ? while( 1 )

? ? {

? ? ? ? USBH_MainDeal( );

? ? }

}

這是USBH_MainDeal 函數(shù)里獲取到描述符的部分不管我接入鍵盤還是鼠標(biāo) 都是鼠標(biāo)一直往右移動

/* Get the data of the HID device connected to the USB host port */

DUG_PRINTF("Mouse Data Uploaded to Endpoint %d\r\n", endp);

} else {

DUG_PRINTF("Mouse Data Upload Failed!\r\n");

然后串口的打印數(shù)據(jù)一直是往一個(gè)方向累加?
