Display a stock symbol on a custom-build multiplexed LED grid using ESP32 SOC and finnhub.io
This project is derived from a few esp32 idf examples:
- peripherals/gpio/generic_gpio/ - basic GPIO operation
- protocols/https_request/ - basic HTTPS requests
- Install ESP-IDF . (The VS Code setup is super easy. see: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/vscode-setup.html)
- Set up "example WIFI connection" parameters
idf.py menuconfig- select
Example Connection Configuration ---> - Enter your WiFi AP details
- Get a finnhub.io API key (it's free): https://finnhub.io/
export FINNHUB_API_KEY=YOUR_KEY_GOES_HERE(cmake will find it automatically during build)- (consider adding this to ~/.zshrc or ~/.bashrc)
Use ESP-IDF to build:
idf.py build
Use ESP-IDF to flash:
idf.py -p YOUR_SERIAL_PORT flash
