stm32实现USB_存储_HID复合设备

stm32实现USB_存储_HID复合设备,采用官方固件库实现,U盘实际上是读卡器

#include “usb_data_process.h“


//HID发送数据
//返回1发送失败 返回0发送成功
u8 HID_Send_Data（u8* bufferu8 length）
{
	if（sendOk == 1）
	{
		if（length == 0）
		{
			SetEPTxStatus（ENDP1 EP_TX_NAK）;//不发送
		}
		else
		{
			UserToPMABufferCopy（buffer GetEPTxAddr（ENDP1） length）;
			SetEPTxCount（ENDP1 length）;
			SetEPTxValid（ENDP1）;//使能发送
			sendOk = 0;//设置发送未完成状态等待发送回调函数将数据发送到主机
		}
		return 0;
	}
	else
	{
		return 1;//上一次的数据还没发送出去所以这次发送失败
	}
}


//HID接收数据处理
u8 HID_Receive_Data（u8* buffer）
{
	u16 length = 0;//获取接收到的数据长度
	u8 i = 0;
	if（ReceiveOk == 1）//有数据
	{
		length = GetEPRxCount（ENDP1）;
		if（length == 0）return 0;
		else
		{
			PMAToUserBufferCopy（buffer GetEPRxAddr（ENDP1） length）;
			SetEPRxValid（ENDP1）;//使能接收
			ReceiveOk = 0;
			
			printf（“hid receive : “）;
			for（i = 0; i < length; i++）
			{
				printf（“%c “buffer[i]）;
			}
			printf（“\r\n“）;
			
			return length;//返回接收到的数据
		}
	}
	else
	{
		//没有数据直接为0
		return 0;
	}
}
