Raspberry Pi Plex Server

Installation

Ensure our operating system is entirely up to date:

sudo apt-get update
sudo apt-get upgrade

在树莓派上点亮微雪1.3寸LCD HAT所需的安装步骤，重新梳理了一下安装顺序。

使用最新Raspbian镜像，联网进行安装。

安装 WiringPi

cd ~
git clone git://git.drogon.net/wiringPi
cd wiringPi
./build

Enable modules in Kernel

In `raspi-config`

Enable SPI under "Interfacing options"

Add modules

$ sudo nano /etc/modules

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

	// CIRCLES:
	// - LITTLE: They appear at all WaveTrend wave crossings
	// - GREEN: The wavetrend waves are at the oversold level and have crossed up (bullish)
	// - RED: The wavetrend waves are at the overbought level and have crossed down (bearish)
	// - PURPLE: Appear when a bullish or bearish divergence is formed and WaveTrend waves crosses at overbought and oversold points
	// - GOLD: When RSI is below 20, WaveTrend waves are below or equal to -80 and have crossed up (DONT BUY WHEN GOLD CIRCLE APPEAR)
	// - None of these circles are certain signs to trade. It is only information that can help you.

	// I am not an expert trader or know how to program pine script as such, in fact it is my first indicator only to study and all the code is copied and modified from other codes that are published in TradingView.
