Introduction

Banana Pi M2+ is mini size development board that offers great computing performance in an ultra portable form factor.It is a 65mm*65mm fantastic mini size board with Allwinner H series chips. It comes with different versions but share the same interfaces.

BPI-M2+ H3

Key Features

Quad-core 1.2GHz Cortex-A7 H3
1GB DDR3
8GB eMMC onboard
WiFi and BlueTooth onboard
10/100/1000Mbps Ethernet Port

Development

Let's get start to develop on BPI-M2P, see amazing things happen.

Basic Development

Prepare to develop

 1.Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System

 2.Using your USB-Serial Connect debug console on M2P

Load your first image on M2P

 1.You could download latest image from our forum
 * Here is the example image link: https://pan.baidu.com/s/1Jf-AZF6a4jZugqqx2QXH3Q

 2.Install bpi-tools on your Ubuntu
 * apt-get install pv
 * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash

 3.After you download the image, insert your TF card into your Ubuntu
 * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card.

 4.After step 3, then you can insert your TF card into M2P, and press power button setup M2P.

Build your own image on M2P

Advanced Development

Bluetooth

Use bluetoothctl tool to operate BT
Execute "bluetoothctl"
If you don't know how to use bluetoothctl, type help, you will see more commands
Execute these commands:

WiFi and Ap mode on M2P

WiFi Client

AP mode

Clear boot

git clone https://github.com/BPI-SINOVOIP/BPI-files/tree/master/SD/100MB
bpi-bootsel BPI-cleanboot-8k.img.gz /dev/sdX

Camara function

We use HDF5640 camara.

Guvcview

Use your UI interface to operate camara
Applications -> Sound & Video -> guvcview

We also have built-in command in /usr/local/bin to test camara
test_ov5640_image_mode.sh
cameratest.sh

IR function

Execute getevent
Use your IR device to send information to M2P

WringPi

GitHub: https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git
We also have built-in test command in /usr/local/bin

RGB 1602 LCD

Execute bpi_test_lcd1602

0.96 Inch OLED Display

Execute bpi_test_52pi

8x8 RGB LED Martix

Firstly you need a GPIO Extend Board for 8x8 LED Martix

Execute bpi_test_gpio40
