1 Introduction

0.96inch 128x64 OLED
  • NanoHat OLED is a small and cute monochrome OLED module with low power consumption. It is 0.96". Its resolution is 128 x 64. It communicates with a master device with I2C.
  • The NanoHat OLED module has the same form factor as FriendlyElec's NanoPi NEO. It can be stacked on a NanoPi NEO.
  • It has three onboard programmable user buttons, a 2.0mm pitch 4-Pin I2C connector.

3 硬件连接

目前支持的开发板有NanoPi NEO/Air。 NanoHat OLED模块和NanoPi NEO/Air尺寸和接口完全相同,可直接堆叠在NanoPi NEO/Air上使用。 参考下图连接模块:
NanoHat OLED_nanopi_NEO

当前支持的开发板:
NanoPi NEO
NanoPi Fire
NanoPi NEO2

4 软件安装

NanoHat OLED的演示程序包含在 NanoHatOLED 软件仓库里,在 Ubuntu core系统下,执行以下命令进行安装:

git clone https://github.com/friendlyarm/NanoHatOLED.git
cd NanoHatOLED
sudo -H ./install.sh


安装脚本会在线下载并安装一系列的软件包,安装时间视网络环境而定,国内用户为了获得更快的安装速度,可以在安装之前先将软件包的源设置为国内源,方法如下:
首先,编辑文件 /etc/apt/sources.list,将里面的内容清空并更改为:

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

然后,编辑(或新建) 文件 $HOME/.pip/pip.conf,将python的pip源设置为国内源,pip.conf内容如下:

[global]
trusted-host =  mirrors.aliyun.com
index-url = http://mirrors.aliyun.com/pypi/simple

完成后成后,执行 sudo apt-get update更新软件包,然后再次执行 ./install.sh 安装脚本安装即可。

5 演示程序的操作说明

演示程序在安装后会在开机时自动运行,并默认显示 日期与时间 画面。
NanoHat OLED配件上的三个按键功能如下:
K1 -> 显示日期时间;
K2 -> 显示开发板的运行状态,例如 IP地址, 负载, 存储状态,CPU温度等信息;
K3 -> 关机操作,并不会立即关机,而是先弹出询问画面,在询问画面的状态下,用 K1 切换 Yes和No选项,K2进行确认;
