This is a fairly basic HTTP client for the ESP32. The microcontroller drives a sh1106 OLED display.
The purpose is to monitor local bus departures so i can check it before leaving the house, potentially saving me a few minutes out in the cold.
The API i'm targeting is specific to Norway, although it is based on a larger project likely used elsewhere.
The crates for esp are not super well documented (imo), so this took a bit of guesswork to implement.
PS: yes, the display is in fact just taped to the board lol
