README
# Experimental demo using ESP32-wrover kit and Rust
The main goal of the demo is to display line directions and departure times of public transport vehicles in Brno.
### What the project does:
- Establish WiFi connection
- Configure ILI9341 display, HTTP Client and SNTP Client
- parse data from website (web scraping)
- init RTC and display current time with parsed data

# Devcontainers
The repository supports:
- [Gitpod](https://gitpod.io/): [](https://gitpod.io/github.com/JurajSadel/wrover-experimental)
- [Vs Code Devcontainers](https://code.visualstudio.com/docs/remote/containers#_quick-start-open-an-existing-folder-in-a-container)
- [GitHub Codespaces](https://docs.github.com/en/codespaces/developing-in-codespaces/creating-a-codespace)
## Build
- Terminal approach:
```
./build.sh [debug | release]
```
> If no argument is passed, `release` will be used as default
- UI approach:
The default build task is already set to build the project, and it can be used
in VsCode and Gitpod:
- From the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette) (`Ctrl-Shift-P` or `Cmd-Shift-P`) run the `Tasks: Run Build Task` command.
- `Terminal`-> `Run Build Task` in the menu.
- With `Ctrl-Shift-B` or `Cmd-Shift-B`.
- From the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette) (`Ctrl-Shift-P` or `Cmd-Shift-P`) run the `Tasks: Run Task` command and
select `Build`.
- From UI: Press `Build` on the left side of the Status Bar.
## Flash
> **Note**
> When using GitHub Codespaces, we need to make the ports
> public, [see instructions](https://docs.github.com/en/codespaces/developing-in-codespaces/forwarding-ports-in-your-codespace#sharing-a-port).
- Terminal approach:
- Using custom `runner` in `.cargo/config.toml`:
```
cargo +esp run [--release]
```
- Using `flash.sh` script:
```
./flash.sh [debug | release]
```
> If no argument is passed, `release` will be used as default
- UI approach:
- From the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette) (`Ctrl-Shift-P` or `Cmd-Shift-P`) run the `Tasks: Run Task` command and
select `Build & Flash`.
- From UI: Press `Build & Flash` on the left side of the Status Bar.
## Wokwi Simulation
- Terminal approach:
```
./run-wokwi.sh [debug | release]
```
> If no argument is passed, `release` will be used as default
- UI approach:
The default test task is already set to build the project, and it can be used
in VsCode and Gitpod:
- From the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette) (`Ctrl-Shift-P` or `Cmd-Shift-P`) run the `Tasks: Run Test Task` command
- With `Ctrl-Shift-,` or `Cmd-Shift-,`
> Note: This Shortcut is not available in Gitpod by default.
- From the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette) (`Ctrl-Shift-P` or `Cmd-Shift-P`) run the `Tasks: Run Task` command and
select `Build & Run Wokwi`.
- From UI: Press `Build & Run Wokwi` on the left side of the Status Bar.
### Debuging with Wokwi
Wokwi offers debugging with GDB.
- Terminal approach:
```
$HOME/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gdb target/xtensa-esp32-espidf/release/brno-public-transport -ex "target remote localhost:9333"
```
> [Wokwi Blog: List of common GDB commands for debugging.](https://blog.wokwi.com/gdb-avr-arduino-cheatsheet/?utm_source=urish&utm_medium=blog)
- UI approach:
Debug using with VsCode or Gitpod is also possible:
1. Run the Wokwi Simulation in `debug` profile
> Note that the simulation will pause if the browser tab is on the background
2. Go to `Run and Debug` section of the IDE (`Ctrl-Shift-D or Cmd-Shift-D`)
3. Start Debugging (`F5`)
4. Choose the proper user:
- `esp` when using VsCode or GitHub Codespaces
- `gitpod` when using Gitpod
