# Bus API & OLED screen for ESP32 and SSD1306
![](https://hackatime-badge.hackclub.com/U087ATD163V/bus-api)

This is a simple client & api for the Taiwan TDX system, which is where you can get the government public transport data. This is made using ESP32C3 and a SSD1306 OLED screen.

This is submitted to SoM: https://summer.hackclub.com/projects/7617/

## How can you try it?
First, register the TDX api from here: https://tdx.transportdata.tw/

Note that this may take a few days to get approved by the government!

Second, setup your server.
1. Get your server provider, this can be Vercel, Netlify, Your own infra, etc...
2. Fill in the default env values.
```
TDX_CLIENT_ID=<<YOUR_TDX_TOKEN>>
TDX_CLIENT_SECRET=<<YOUR_TDX_TOKEN>>
ACCESS_TOKEN=<<YOUR_APPS_ACCESS_TOKEN>>
```
3. Spin up the app!

Third, get your ESP32 C3 and a SSD1306 OLED screen.

Forth, download the entire repo, and open client.ino in the Arduino IDE.

Fifth, install the required libraries and the offical ESP32 source.
1. Put `https://dl.espressif.com/dl/package_esp32_index.json` into the settings text box.
2. Go to the board manager at the sidebar and search for ESP32, and download the offical ESP32 package (**NOT THE ARDUNIO PACKAGE**)
3. Go the library manager and download a few packages, this includes: U8G2 & ArduinoJson
4. Change to YOUR values in values.h (the example is example-values.h)
5. Flash it!
