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

BPI:bit for Arduino IDE source code

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.

How to install Arduino IDE

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
