esp-clock :crab:

This project was inspired by the rusty-clock project

The initial goal of the project was just to implement clocks with brand new ESP32-C3-RUST-BOARD, but over time, new ideas and more use cases began to appear.

Generally, project is created to demonstrate the capabilities of the new board in the Rust language, but now I've taken the direction to create a monitoring system based on the RUST-BOARD, so ch so you have two possibilites how to run this project:

On the RUST-BOARD itself, enabling the esp32c3_rust_board_ili9341 feature, in Cargo.toml file. On-board sensors will be used.
Using another chip (list of availible configurations somewhere below), activating the corresponding feature in Cargo.toml file.

You can learn more about RUST-BOARD here

Important : every configuration other than esp32c3_rust_board_ili9341 requires Wi-Fi connection and uses MQTT messaging to revceive data from RUST-BOARD, which is measuring temperature and humidity

MQTT measurements sender is implemented here also by myself and of course it's also for RUST-BOARD since this project is dedicated to it

Hardware

ESP32-C3-RUST-BOARD

The basic use case for this project involves the use of a RUST-BOARD and ILI9341 display.

Used pins

ILI9341	ESP-RUST-BOARD
RST	GPIO3
CLK	GPIO6
D_C	GPIO21
CS	GPIO20
MOSI	GPIO7

ESP32-С3-RUST-BOARD with ILI9341 display

Corresponding Wokwi project

Features

Enable esp32c3_rust_board_ili9341 feature if you want to use RUST-BOARD and it's on-board sensors with ili9341 display
Enable esp32c3_ili9341 if you're using ESP32-C3 board and ili9341 display OR if you want to use RUST-BOARD with MQTT-messaging to receive temperature and humidity from another RUST-BOARD
Enable esp32s3_ili9341 if you're using ESP32-S3 board and ili9341 display
Enable esp32s2_ili9341 if you're using ESP32-S2 board and ili9341 display
Enable esp32s3_usb_otg if you're using ESP32-S3-USB-OTG board and ili9341 display

Warning

Not optimized yet.

Enable esp32s2_usb_otg if you're using ESP32-S2-USB-OTG board and ili9341 display

Warning

Not optimized yet.

Important : If you using any configuration with Wi-Fi, it will set time automatically. Also, if you're using esp32c3_rust_board_ili9341 configuration and you want to enable Wi-Fi time setting - just add --features wifi to execution command. Otherwise, you will need to set the time manually at THESE lines of code

Plans

Model a box :alarm_clock:
Make some kind of a monitoring system with the ability to place several sensors(RUST-BOARDS) over the room/building/whatever
Optimize project for other targets (ESP32-S3-BOX, ESP32-S2-Kaluga-1, ESP32-S2-HMI-DevKit-1)
Grafana integration :bar_chart:

Dev Containers

This repository offers Dev Containers supports for:

Note

In order to use Gitpod the project needs to be published in a GitLab, GitHub, or Bitbucket repository.

In order to use GitHub Codespaces the project needs to be published in a GitHub repository and the user needs to be part of the Codespaces beta or have the project under an organization.

If using VS Code or GitHub Codespaces, you can pull the image instead of building it from the Dockerfile by selecting the image property instead of build in .devcontainer/devcontainer.json. Further customization of the Dev Container can be achived, see .devcontainer.json reference.

When using Dev Containers, some tooling to facilitate building, flashing and simulating in Wokwi is also added.

Build

Terminal approach:
```
scripts/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 VS Code and Gitpod:
- From the 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 (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.

Terminal approach:
- Using flash.sh script:
```
scripts/flash.sh [debug | release]
```
  If no argument is passed, release will be used as default
UI approach:
- From the 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.
Any alternative flashing method from host machine.

Wokwi Simulation

When using a custom Wokwi project, please change the WOKWI_PROJECT_ID in run-wokwi.sh. If no project id is specified, a DevKit for esp32c3 will be used.

Warning

ESP32-S3 is not available in Wokwi

Terminal approach:
```
scripts/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 VS Code and Gitpod:
- From the 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 (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.

Warning

The simulation will pause if the browser tab is in the background.This may affect the execution, specially when debuging.

Debuging with Wokwi

Wokwi offers debugging with GDB.

Terminal approach:

$HOME/.espressif/tools/riscv32-esp-elf/esp-2021r2-patch3-8.4.0/riscv32-esp-elf/bin/riscv32-esp-elf-gdb target/riscv32imc-esp-espidf/debug/esp_clock -ex "target remote localhost:9333"

Wokwi Blog: List of common GDB commands for debugging.

UI approach:
1. Run the Wokwi Simulation in debug profile
2. Go to Run and Debug section of the IDE (Ctrl-Shift-D or Cmd-Shift-D)
3. Start Debugging by pressing the Play Button or pressing F5
4. Choose the proper user:
  - esp when using VS Code or GitHub Codespaces
  - gitpod when using Gitpod
