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

GPIO

  • echo xxx > /sys/class/gpio/export
  • echo in/out > /sys/class/gpio/gpioxxx/direction
  • echo 0/1 > /sys/class/gpio/gpioxxx/value

Check the base gpio, you could see mine is 233

For example: if you want to change gpio 22 as out highlevel, you need input commands like this:

  • echo 255(22+233) > /sys/class/gpio/export
  • echo out > /sys/class/gpio/gpio255/direction
  • echo 1 > /sys/class/gpio/gpio255/value

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

Camara function

We use HDF5640 camara.

Guvcview

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

Guvcview ov5640.png

  • 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

RGB 1602 LCD

  • Execute bpi_test_lcd1602

WringPi 1602 LCD.png

0.96 Inch OLED Display

  • Execute bpi_test_52pi

WringPi 0.96 OLED.png

8x8 RGB LED Martix

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