led_matrix_clock_with_weather

Clock with weather display designed to be run on a raspberry pi (tested on 3B) to a 128x64 matrix array

Built on https://github.com/hzeller/rpi-rgb-led-matrix

Gets local weather based on lat\lon from OpenWeather (Need free API key)

Install Dependencies

sudo apt install build-essential git libcurl4-openssl-dev nlohmann-json-dev

Build rpi-rgb-led-matrix

You can probably just build the examples, so follow the instructions at https://github.com/hzeller/rpi-rgb-led-matrix to do that (But you probably already have if you're here)

Get lodepng

cd ./lodepng
curl -O https://raw.githubusercontent.com/lvandeve/lodepng/master/lodepng.h
curl -O https://raw.githubusercontent.com/lvandeve/lodepng/master/lodepng.cpp

Edit the makefile with your dependency locations

Add your Open Weather API Key and change your weather location

std::string api_key = "API_KEY_HERE";

Build the clock

make

Run it!

./clock

This takes the rpi-rgb-led-matrix parameters, so if you are using a chain of 2 64x64 displays for example:

sudo ./clock --led-rows=64 --led-cols=64 --led-chain=2

Any display related issues, you'll have more luck at https://github.com/hzeller/rpi-rgb-led-matrix

Icons can be replaced either by 32x32 pngs in the icon folder, or you can change them to use simple shape drawn images (See the "Snow" weather in the code for an example of that)
