You'll now connect the LinkIt 7697 HDK to your computer and make sure it is properly detected under Devices and Printers on Windows PC.
LinkIt 7697 connects to your computer through the COM port interface. The COM port interface is provided by the onboard CP2102N USB-to-UART bridge chipset. It then connects to the UART0 port of the MT7697 SoC. This UART0 port can be used to program the flash memory attached to the MT7697 chipset. It can also be used as a communication channel for your program through terminal programs of your choice, such as TeraTerm or Putty.
Since the board relies on CP2102N to provide the COM port functionality, you'll need to install the driver so that your computer to recognize it. The board uses the default USB VID and PID of the CP2102N, so you need to install the official CP2102N driver from the vendor's website.
Install CP2102N USB-to-UART Driver
Download and install the CP2102N USB to UART Bridge VCP driver here. Choose the Download VCP option according to your operating system version.
Connect LinkIt 7697 to Computer
After driver installation, simply use a micro-USB cable to connect the board to your computer. The onboard PWR LED should light up, as shown below:
Confirm Driver Installation
After connecting the board to the computer, follow these steps to confirm if the driver is installed properly:
- Open Device Manager control panel.
- In the Ports (COM & LPT) section, an item named Silicon Labs CP210x USB to UART Bridge (COMXYZ) should appear. The number XYZ can be different on each computer. This is the COM port you'll be using to program and interact with the LinkIt 7697 board.
You're now ready to download project binaries to the LinkIt 7697 board.
