I have programmed something in labview to access some data through usb port from stm primer2.
Now i am switching the whole program to olimex stmh103 board.
when i connect the usb port of the olimex board to pc, the red light is turned on which is the indication of power supply but i also want a communication through usb then should i also connect another power supply to extension header 2 at pin 25 and 26 (which are gnd and vin respectively).
I am not able to communicate through usb because labview program configures for the virtual com port and i should identify which com port i have connected. Normally if i connect usb port i can see on device manager but with olimex board i cannot see on the device manager. I can only see the connection if i conect jtag interface (or debugger) to olimex.
So how can i communicate to stm32 microcontroller available in olimex board through usb and that should be compatible to labview as well.
I look forward for suggestion and help.
Thanks in advance.
