Step 2: Connect USB on ARMmite PRO

The ARMmite PRO   Eval Kit comes with a USB dongle and cable. This dongle and cable allows you to connect the ARMmite PRO directly to a computer equipped with USB.  When connected to a PC power is supplied by the PC, the optional power connection is not required, but both may be safely connected.

The USB dongle from Cordium allows you to download C programs WITHOUT installing jumpers or pushing buttons.

Connect the black wire to GND. 

Picture shows the 2 pins that must be jumpered to load a C program, a 2 pin header and a jumper block can be used without soldering it into the PCB (illustrated below)

The SparkFun USB Dongle does not control the RTS line so the C jumper must also be installed to download a C program.

Locate the USB jack on your computer and plug the other end of the cable into it.

Most PC's will sound a tone that indicates a new USB device has been connected.  Most Windows  Vista and 7 systems will either include the FTDI device driver or are able to download it automatically from the network.

If your system is unable to do that.  Run the FTDI driver installation setup in the \Program Files\Coridium\Windows_drivers directory.  This will install the proper drivers for the FTDI chips we use for interfacing to the USB. 

Up to date details are at the www.ftdichip.com VCP drivers page. 

 

Driver Installation Complete, Confirm USB Connection

The Eval PCB or the ARMmite will be powered from the USB bus.  It may also be connected to a 5-12V DC power source simultaneously.

To verify connection with the USB and PC the LED on the Eval PCB should light up.
