Youtube TFT Display Board
Fetch data from an Youtube channel using Google API's. For ease of usage and development I decided to use MicroPython running on an ESP32 Wifi board. The TFT Display used was one based on ST7735R driver, but this can easily be ported to other by just using different drivers available here.
Hardware
3D Printed case
I added the 3d models for the case that I made. I built it on Tinkercad.
Instructions
Follow the steps to build you own:
- This is a working in progress, the wiring still missing.
Setup Youtube API Key
- Go to Youtube Developers Portal.
- Follow the guide "Calling the API"
- Go to Developer Console
- Go to Credentials
- Click on "Create Crendential" then "API Key"
- Copy that API Key and click on "Restrict Key"
- Add "Youtube Data API v3" to the restriction list.
- At the top search bar, search for "Youtube Data API" and enable that API.
Setup and install micropython on ESP32
Install tools and download micropython binary
$ pip3 install adafruit-ampy
$ pip3 install esptool
$ curl -o esp32.bin http://micropython.org/resources/firmware/esp32-20190125-v1.10.bin
For interactive development (Optional)
$ git clone https://github.com/goatchurchprime/jupyter_micropython_kernel.git
$ pip3 install jupyter
$ pip3 install -e jupyter_micropython_kernel
$ python3 -m jupyter_micropython_kernel.install
$ jupyter kernelspec list
Find serial port
$ ls /dev/tty.*
# In my case was /dev/tty.SLAB_USBtoUART
Clean flash and send micropython binary
$ esptool.py --port /dev/tty.SLAB_USBtoUART erase_flash
$ esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 460800 write_flash -z 0x1000 esp32.bin
Install TFT lib
$ curl -o st7735.py https://raw.githubusercontent.com/adafruit/micropython-adafruit-rgb-display/master/st7735.py
$ curl -o rgb.py https://raw.githubusercontent.com/adafruit/micropython-adafruit-rgb-display/master/rgb.py
$ ampy --port /dev/tty.SLAB_USBtoUART put rgb.py
$ ampy --port /dev/tty.SLAB_USBtoUART put st7735.py
Install project code
Fill the config.py file with you settings for Youtube API, Channel and Wifi connection.
$ ampy --port /dev/tty.SLAB_USBtoUART put config.py
$ ampy --port /dev/tty.SLAB_USBtoUART put main.py /main.py
