BPI:bit for Arduino

About BPI:bit

This product adopts esp-wroom-32 module as the core for design, and supports wi-fi, bluetooth, BLE and other wireless communication modes.

The BPI bit (also referred to as BPI-bit, stylised as bpi:bit) is an ESP32 with 32-bit Xtensa LX6 dual-core processor based embedded system. It supports Webduino, Arduino, MicroPython as well as Scratch X programming environments.

More about Banana Pi BPI:bit,please see :BPI-Bit

BPI:bit for Arduino-IDE

Wired connection board

Connect the boards to your computer via the MicroUSB wire, it is same as BPI:bit with microPython.

please see this documents:2 Wired connection board

Development extension package

Arduino-esp32 developer kit, click the previous link to get the developer kit

From arduino-esp32, an open source project of github (espressif), it is recommended to use github DeskTop tool to update the suite at any time.

Windows installation instructions

• Download and install the latest version of the Arduino IDE, Windows Installer from arduino.cc

• Download the arduino development extension package from the espressif/arduino-esp32 open source project

• Unzip the Arduino expansion package: [ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32

ARDUINO_SKETCHBOOK_DIR:generally is C:/Users/[YOUR_USER_NAME]/Documents/Arduino listed below the "Sketchbook location" in the Arduino preference

• In turn open directory [ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32 /tools, and double-click the get operation. Exe

• When get.exe runs out, you should see the following files in the directory

• Insert the BPI:bit board and wait for the driver to install (or manually install) Serial CH341

• Run the Arduino IDE

• Select your version (bpi-bit) Tools>Board menu

• Select the COM port to which the BIT board is connected, such as COMx

• Compile and upload your engineering code (BIT board design has automatic recording circuit, just click to upload)

Debian/Ubuntu Linux OS installation instructions

• Get and install the latest version of the arduino IDE from the arduino.cc website

• Open the terminal and execute the following command (copy-> paste and click enter):

sudo usermod -a -G dialout $USER && \
sudo apt-get install git && \
wget https://bootstrap.pypa.io/get-pip.py && \
sudo python get-pip.py && \
sudo pip install pyserial && \
mkdir -p ~/Arduino/hardware/espressif && \
cd ~/Arduino/hardware/espressif && \
git clone https://github.com/espressif/arduino-esp32.git esp32 && \
cd esp32 && \
git submodule update --init --recursive && \
cd tools && \
python2 get.py

• Restart the Arduino IDE

• If you have installed arduino to ~/directory, please execute the following code. If not, please start from mkdir-p ~/ arduino /hardware:

cd ~/Arduino/hardware
mkdir -p espressif && \
cd espressif && \
git clone https://github.com/espressif/arduino-esp32.git esp32 && \
cd esp32 && \
git submodule update --init --recursive && \
cd tools && \
python2 get.py

Mac OS install arduino IDE

• Get and install the latest version of the arduino IDE from the arduino.cc website
• Open the terminal and execute the following command (copy-> paste and click enter):

sudo usermod -a -G dialout $USER && \
sudo apt-get install git && \
wget https://bootstrap.pypa.io/get-pip.py && \
sudo python get-pip.py && \
sudo pip install pyserial && \
mkdir -p ~/Arduino/hardware/espressif && \
cd ~/Arduino/hardware/espressif && \
git clone https://github.com/espressif/arduino-esp32.git esp32 && \
cd esp32 && \
git submodule update --init --recursive && \
cd tools && \
python2 get.py

The ~/Documents/Arduino directory should be consistent with the "Arduino" > "preference" > "Sketchbook location" (after the software starts). You may need to change the above command if you need to!

If you receive the following error. Use xcode-select --install to install the command-line development tool and try the above command again:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
xcode-select --install

If you receive an error message: IOError: [Errno socket error] [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) while running python get.py, you can try using python3 instead of python

• Restart the Arduino IDE
