PIC24FJ \u0026lt;-> LabView.

The following document details some of the functions and procedures to make a connection by CDC (serial port emulation) with a 18F family microcontroller with USB support and LabView. We welcome comments, corrections and / or corrections suggestions for this document.

Connection CDC PIC \u0026lt;-> LabView

The hardware used for this example has 5 Pushbuttons connected on port A (A1.. A5) and 8 leds on port B (B0.. B7).
