Problem sending ALT+B in ex_usb_kbmouse2 example code.
PostPosted: Sun Oct 23, 2011 12:01 pm     Reply with quote
I have a problem using the PIC18F2550 emulating a mouse and keyboard using USB HID.
I'm using the 4.106 version of ccs and example ex_usb_kbmouse2.
My problem is I'm not able to send special key combinations (alt, control, shift).

If I try to send Alt + B does not work.

The code is:
Code:

if (BUTTON_PRESSED())    {
       
     tx_msg[8]={2,0,0,0,0,0,0,0};
      tx_msg[1] = 4; //send press Alt?
   usb_put_packet(1,tx_msg,sizeof(tx_msg),USB_DTS_TOGGLE);
                delay_ms(50);
       
   tx_msg[3] = 5 // Send press B.
   usb_put_packet(1,tx_msg,sizeof(tx_msg),USB_DTS_TOGGLE);
          delay_ms(50);
     
   tx_msg[3] = 0 // send no key press.
   usb_put_packet(1,tx_msg,sizeof(tx_msg),USB_DTS_TOGGLE);
          delay_ms(50);

   tx_msg[1] = 4; //send no Alt press
   usb_put_packet(1,tx_msg,sizeof(tx_msg),USB_DTS_TOGGLE);
        delay_ms(50);

        delay_ms(500);
                  }

The rest of the code is the example ex_usb_kbmouse2.

What is the correct way to send Alt +1?

Some sample code?

Thanks and sorry for my bad English.
