help me! mình làm phần giao tiêp usb dùng mikro c lập trình cho pic 18f4550 nhưng kết nôi usb toàn báo k nhận diện được usb. ai biết chỉ mình với, mình dùng lớp hid ở usb đây là code test của mình:
unsigned char readbuff[64] absolute 0x500; // Buffers should be in USB RAM, please consult datasheet
unsigned char writebuff[64] absolute 0x540;
char cnt;
char kk;
void interrupt(){
USB_Interrupt_Proc(); // USB servicing is done inside the interrupt
}
void main(void){
ADCON1 |= 0x0F; // Configure all ports with analog function as digital
CMCON |= 7; // Disable comparators
HID_Enable(&readbuff,&writebuff); // Enable HID communication
while(1){
while(!HID_Read());
for(cnt=0;cnt<64;cnt++)
writebuff[cnt]=readbuff[cnt];
while(!HID_Write(&writebuff,64)) ;
}
}
unsigned char readbuff[64] absolute 0x500; // Buffers should be in USB RAM, please consult datasheet
unsigned char writebuff[64] absolute 0x540;
char cnt;
char kk;
void interrupt(){
USB_Interrupt_Proc(); // USB servicing is done inside the interrupt
}
void main(void){
ADCON1 |= 0x0F; // Configure all ports with analog function as digital
CMCON |= 7; // Disable comparators
HID_Enable(&readbuff,&writebuff); // Enable HID communication
while(1){
while(!HID_Read());
for(cnt=0;cnt<64;cnt++)
writebuff[cnt]=readbuff[cnt];
while(!HID_Write(&writebuff,64)) ;
}
}
