Get Started with Wio Terminal


The Wio Terminal is a SAMD51-based microcontroller with Wireless Connectivity powered by Realtek RTL8720DN that’s compatible with Arduino and MicroPython. Currently, wireless connectivity is only supported by Arduino. It runs at 120MHz (Boost up to 200MHz), 4MB External Flash and 192KB RAM. It supports both Bluetooth and Wi-Fi providing backbone for IoT projects. The Wio Terminal itself is equipped with a 2.4” LCD Screen, onboard IMU(LIS3DHTR), Microphone, Buzzer, microSD card slot, Light sensor, and Infrared Emitter(IR 940nm). On top of that, it also has two multifunctional Grove ports for Grove Ecosystem and 40 Raspberry pi compatible pin GPIO for more add-ons.

Materials required

Wio Terminal x 1
Computer x 1
USB Type-C Cable x 1

Connect the Wio Terminal to your computer via USB cable. The blue LED on the back should light up.

Software
Step 1. You need to Install an Arduino Software.


Launch the Arduino application

Double-click the Arduino IDE application you have previously downloaded.

NOTE
If the Arduino Software loads in a different language, you can change it in the preferences dialog. See the [Arduino Software (IDE) page](https://www.arduino.cc/en/Guide/Environment#languages) for details.


Step 2. Open the Blink example
Open the LED blink example sketch: File > Examples >01.Basics > Blink.


Blink Path
Step 3. Add the Wio Terminal Board Library
1.Open your Arduino IDE, click on File > Preferences, and copy below url to Additional Boards Manager URLs:

https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json



2.Click on Tools > Board > Board Manager and Search Wio Terminal in the Boards Manager.


The keyword is Wio Terminal
Step 4. Select your board and port
You'll need to select the entry in the Tools > Board menu that corresponds to your Arduino. Selecting the Wio Terminal.

Choose the right board
Select the serial device of the Wio Terminal board from the Tools -> Port menu. This is likely to be COM3 or higher (COM1 and COM2 are usually reserved for hardware serial ports). To find out, you can disconnect your Wio Terminal board and re-open the menu; the entry that disappears should be the Arduino board. Reconnect the board and select that serial port.

NOTE
For Mac User, it will be something like `/dev/cu.usbmodem141401`


Choose the right port
Step 5. Upload the program
Now, simply click the Upload button in the environment. Wait a few seconds and if the upload is successful, the message "Done uploading." will appear in the status bar.


Upload the code
A few seconds after the upload finishes, you should see the LED at the bottom of the Wio Terminal start to blink. If it does, congratulations! You've gotten Wio Terminal up-and-running. If you have problems, please see the FAQ suggestions.

If you are not able to upload the sketch, mostly it's because Arduino IDE was not able to put Wio Terminal to bootloader mode. (Because MCU was halted or your program handling USB,) Workaround is putting your Wio Terminal to bootloader mode manually, as shown in FAQ.

Please feel free to go though other tutorials of Wio Terminal and start building your IoT projects!

FAQ
Reset Wio Terminal:

Enter Bootloader:
This is very useful when Wio Terminal crashes or somehow USB serial is not showing up in Arduino IDE. Slide the switch twice very quickly, as followed:


Once Wio Terminal is in the Bootloader mode, the blue LED will start to breath in a way that is different to blinking. Check the port again and it should appeared.

Test with SWD
There are two ways to use SWD to test and debug with Wio Terminal:

From the back of the PCB testing ports.


On the left is the testing ports for ATSAMD51:

SWCLK
SWDIO
SWO
RST
GND
3V3
On the right is the testing ports for RTL8720DN:

CHIP
RXD
TXD
GND
3V3
If you have very frequent debugging needs, you can add SWD debugging to one of the Grove interfaces in the following ways:



The picture shows the two unmounted resistor positions. You can connect these two pads by soldering a 0 ohm resistor or shorting it. This will connect the SWD interface (SWDIO / SWCLK) of ATSMAD51 to Grove in parallel on the interface.

After our test, the SWD interface is connected in parallel in this way. When powering on and resetting, you need to make sure that the Grove interface is not connected to any Grove module (the module may have pull-up / pull-down resistors, which will affect it), otherwise it will Enter SWD mode directly and cannot run in normal mode (that is, SWDCLK cannot be pulled low during power-on or reset)

In addition to power-on and reset, when using SWD, Digital, Analog, Serial, I2C, there will be no interference, you can switch at any time, but in order to avoid possible problems, we still recommend removing this after completing the program debugging Connection of two pads.

Library File Name Conflicts
After you install seeed-arduinocore-samd, the core will download some library files to drive different devices at the same time, such as TFT_eSPI.h, etc. When you upload the program, an error will occur and the compiler will prompt you that multiple library files are found. E.g:

Multiple libraries were found for "TFT_eSPI.h"

Used: C:\Users\Dave\Documents\Arduino\libraries\TFT_eSPI-master

Not used: C:\Users\Dave\AppData\Local\Arduino15\packages\Seeeduino\hardware\samd\1.8.2\libraries\Seeed_Arduino_LCD


If you use a seeed-SAMD device, please select and use the library file in the seeed folder and move the conflicting library file out of the arduino library.

When you use other devices, please remove the library files in the seeed folder and keep the compiler calling only one library file. This can solve the incompatibility problem caused by different versions of library files with the same name.



You may refer to the specific library lists here: https://github.com/Seeed-Studio/ArduinoCore-samd/tree/master/libraries
