我写的代码也顺便帮我看看哪有问题吧！多谢#include // part specific constants and macros
#include "PSoCAPI.h" // PSoC API definitions for all User Modules
extern BYTE UsbResetFlag;
void main(void)
{
BYTE str[8];//used to save data from pc
BYTE EpState;//used to save the endpoint state
WORD Size;//used to save the size of the data from pc
M8C_EnableGInt;
USBFS_Start(0,USB_5V_OPERATION);//start usb with 5
while(1)
{
if(UsbResetFlag)
{
while(!USBFS_bGetConfiguration());// Wait for the USB device to enumerate
USBFS_EnableOutEP(1);
EpState=USBFS_bGetEPState(1);//Gets the Endpoint state for the specified endpoint
while(!USBFS_bGetEPAckState(1));//Determines whether or not an ACK transaction occurred
//on this endpoint by reading the ACK bit
//in the control register of the endpoint
Size=USBFS_wGetEPCount(1);//This functions returns the value of the endpoint count register
USBFS_bReadOutEP(1,str,8);//Moves the specified number of bytes from endpoint RAM to data RAM
LCD_Start();//display the state and the data
LCD_Position(0,1);
LCD_PrHexByte(EpState);
LCD_Position(0,6);
LCD_PrHexByte(Size);
LCD_Position(1,1);
LCD_PrString(str);
UsbResetFlag = 0;
}
}
