Seeed Technology Co., Ltd ReSpeaker Core v2 User Guid
Step 2. Check at your computer if the serial port has risen:
Windows: check the device manager, there should be new serial deviced named
COMx
which x is an
increasing number. If you use windows XP/⅞, maybe you need install
windows CDC drivers
.
Linux:
ls /dev/ttyACM*
, you should get
/dev/ttyACMx
where x will vary depending on which USB port
you used.
Mac:
ls /dev/cu.usb*
, you should get
/dev/cu.usbmodem14xx
where xx will vary depending on which
USB port you used.
Step 3. Use your favorite serial debugging tool to connect the serial port, the serial has: 115200 baud rate,
8Bits, Parity None, Stop Bits 1, Flow Control None. For examples:
Windows: use
PUTTY
, select
Serial
protocol, fill in the correct COM port of ReSpeaker Core
v2.0,
115200
baud, 8Bits, Parity None, Stop Bits 1, Flow Control None.
Linux: Depend on your USB To TTL Adapter, it could be
screen /dev/ttyACM0(,1, and so on)
115200
or
screen /dev/ttyUSB0(,1, and so on) 115200
Mac: Depend on your USB To TTL Adapter, it could be
screen /dev/cu.usbserial1412(,1422, and so on)
115200
or
screen /dev/cu.usbmodem1412(,1422, and so on) 115200
Step 4. The default user name is
respeaker
, and password is
respeaker
too.
Connection via The UART port
In this section we will guide you how to establish a connection from your computer to your ReSpeaker using
your USB to TTL adapter which will be connected to the ReSpeaker's Uart port (Uart port located just to the left
of the ReSpeaker speaker plug).
Step 1. Connect Uart port and your PC/Mac with an USB To TTL Adapter. Note that the voltage of RX/TX
are 3.3V. If you don't have an USB To TTL Adapter, you can click
here
to get one.
Step 2. Use the following Serial debugging tools with 115200 baud:
Windows: use
PUTTY
, select
Serial
protocol, fill in the correct COM port of ReSpeaker Core v2.0,
115200 baud, 8Bits, Parity None, Stop Bits 1, Flow Control None.
Linux: Depend on your USB To TTL Adapter, it could be
screen /dev/ttyACM0(,1, and so on)
115200
or
screen /dev/ttyUSB0(,1, and so on) 115200
.
Mac: Depend on your USB To TTL Adapter, it could be
screen /dev/cu.usbserial1412(,1422, and so on)
115200
or
screen /dev/cu.usbmodem1412(,1422, and so on) 115200
.
Step 3. The login user name is respeaker, and password is respeaker too.
Step 4. If you do not have a USB to TTL Adapter, you may also use an Arduino. If using an Arduino,
connect one end of a jumper wire to the RESET pin on the Arduino and the other end to the GND pin on
the Arduino. This will bypass your Arduino's ATMEGA MCU and turn your Arduino into a USB to TTL
adapter, see video tutorial
here
. Now connect the GND pin on the Arduino to the GND pin on the Uart
port of the Respeaker. Connect the Rx pin on the Arduino to the Rx pin on the Uart port of the Respeaker.
Connect the Tx pin on the Arduino to the Tx pin on the Uart port of the Respeaker. And lastly, connect the
Arduino to your PC/Mac via the Arduino's USB cable. Now check that your Mac or Linux PC finds your
Arduino by typing this command.
ls /dev/cu.usb* (Mac)
ls /dev/ttyACM* (Linux)
You should get back something like:
/dev/cu.usbmodem14XX where XX will vary depending on which USB port you used (on Mac)
/dev/ttyACMX where X will vary depending on which USB port you used (on Linux)
