Hello community of LCDinfo.

For my school project, I have chosen to work with the USBD480 Display.

The project that I need to make requires that it must run on a microcontroller which operates with Linux system.

Due to this being the first project for me to work with Linux system, it seems difficult to find information for miscellaneous parts.

To get to the point, my problem at this point is to initialize the library called "libusb.h", since that the display connects to the microcontroller through a usb.

My goal to start with is to establish a connection between the USBD480 Display and a computer that has Linux running.

Any information given will be appreciated.

My test.c program:

$gcc test.c

Code:
#include </home/admin/arm-linux-gcc/libusb/libusb-1.0.9/libusb/libusb.h>

int main (int argc, char **argv) //
{
   usb_init();

   return 0;
}


Output:

Code:
/tmp/cchkSBid.o: In function `main':
test.c:(.text+0x7): undefined reference to `usb_init'
collect2: ld returned 1 exit status

Hi,

Try adding -lusb to that command line to include libusb.

Something like
Code:
$gcc -lusb test.c

Hi,

Were you able to solve your problems and get the USBD480 display working?
