[SOLVED] Undeclared Identifier 'USB_Interrupt_Proc' - HELP

[eebhoi01]

Hello guys,

I am studying how to use PIC18 right now, I have found a good example here in edaboard https://www.edaboard.com/blog/1512/. I am sure I did follow the instructions in here, but I am stuck in "build" process. I can't build the project because MikroC says the error Undeclared Identifier 'USB_Interrupt_Proc'.

unsigned char Read_Buffer[16] absolute 0x500;
unsigned char Write_Buffer[16]absolute 0x510;
unsigned char num,flag;




void interrupt()
{
 USB_Interrupt_Proc();
 TMR0L = 100;             //Reload Value
 INTCON.TMR0IF = 0;       //Re-Enable Timer-0 Interrupt
}

By the way I am using PIC18f4550 - MikroC - Proteus in my study. Also the 'USB_Interrupt_Proc' isn't corrected by MikroC (underlined with a red fuzzy line), I think my USB library is enabled that makes me confused more why is this so.

P.S I also have tried running the example of MikroC about USB in the "help". When I build it, it says the same error.

Looking forward for your help guys.

You need to add this descriptor file into your Project.

Go to Project --> Add Files to Project

Thank you for your reply, but i already have done including the descriptor in the project ^_^...

 

[jayanth.devarayanadurga]

You have to check the USB Library in the Library Manager. Have you added the descriptor file to your project?
Zip and post your mikroC files and proteus .dsn file.

here it is sir...



by the way the descriptor file is named "HIDsample"

I am not getting the error you mentioned. I am getting the errors shown in the attached image. Try to reinstall mikroC.

Really Sir? I guess I have to reinstall mikroC then. THank you

It is working. See the attached image. You had selected wrong PIC. Instead of selecting PIC18F4550 you had selected PIC18F4450.

yes I have same problem usb1 project from advanced PIC Microcontroller projects in c with PIC18f
