ESP-32 Wind indicator

====

Counterpart of [ESP32 Wind sensor](https://github.com/elmot/esp-windsensor-mast).

The firmware is assembled for classic ESP32, but also works on ESP32-S3.

Communication

---

Connects as a WiFi station and receives NMEA-183 data via UDP port 9000

WiFi parametes are set via *idf.py menuconfig*

Input pins

---

Both could be adjusted using *idf.py menuconfig*

* Backlight up button GPIO18

* Backlight down button GPIO19

Input pins

---

Both could be adjusted using *idf.py menuconfig*

* GPIO5 - Alarm LED

* GPIO4 - Alarm LED inverted

Display

---

Display unit is connected via unidirectional UART(GPIO17).

There are two variants of the display unit:

* STM8 MCU + Winstar WG240128B display. There are multiple clones of it. STM8 firmware is here: [stm8-display-bridge](stm8-display-bridge). Unfortunately STM8 is totally deprecated now. If there is some interest, I'll port it to some cheap ARM-based 5V MCU.

* Emulator on Raspberry Pi Pico + [Pimoroni Pico Display Pack 2.0](https://shop.pimoroni.com/products/pico-display-pack-2-0). See [rpi-display](rpi-display)

How to flash the main unit

----

There are multiple ways to flash ESP32. The easiest way is [esptool-js](https://espressif.github.io/esptool-js/). 

Take binaries from [the latest release](//github.com/elmot/esp-windsensor-deck/releases/latest). 

Flash addresses are

| File                    | Address |
