Installing LinkIt Smart 7688 Duo COM Port Driver
After you’ve installed the board package, connect LinkIt Smart 7688 Duo to your computer and
you should see a USB serial COM port in the device manager with the following port ID:
•
Boot loader COM port:
VID=0x0E8D, PID=0xAB00
•
Arduino Sketch COM port:
VID=0x0E8D, PID=0xAB01
Next, you’ll need to install drivers depending on your operating system. The steps are:
•
For Windows 10, there is no need to install a driver. However, extra steps are needed to
ensure Windows 10 recognizes the board. Connect LinkIt Smart 7688 Duo to your Windows
10 machine, then quickly press the MCU reset button twice within 700 milliseconds. The
system should now recognize LinkIt Smart 7688 Duo as a
USB Serial Device (COM5)
.
The number 5 may be different on different machines. You only need to do this during the
1
st
time connecting the board to your Windows machine.
•
For Windows 8, the system may block the driver installation. Follow this
to know how
to disable driver signature enforcement on Windows 8. After the signature enforcement is
disabled, follow the steps in Windows 7 below to install the driver.
•
For Windows 7, find the Serial COM port INF driver in the following path. You can also
install it from
{ARDUINO_IDE_PREFERENCE_LOCATION}Arduino15/packages/LinkIt/hardware/avr/0.1
.5/driver/linkit_smart_7688.inf
You’ll find the Arduino preference location at File > Preferences, see the preference.txt
path as shown in
