sending int18 by usb
PostPosted: Thu Nov 20, 2008 2:49 pm     Reply with quote
Hello, I was trying to send a int18 by usb, but the PC always received one byte with 0 and another with 14, the following is part of the code
Code:

int16 Pu=500;
int16 *ptr;

void main(){
   ptr=Pu;
   if(usb_enumerated()){
      usb_put_packet(1, ptr, 2, USB_DTS_TOGGLE);
   }
   output_toggle(PIN_B1);
}


I configured the usb correctly because I don't have problem sending one byte.

ptr=&Pu;

You are currently sending the contents of _address_ 500, which could contain anything...

Best Wishes
