ESP32-C3 Rust Tutorials

Various embedded Rust tutorials using the ESP32-C3. We'll work towards making a remote data logger by first implementing peripherals we will need to build the larger project.

Each tutorial below has a YouTube video link where I will start with a blank project and implement a peripherals using the latest esp-idf-hal version.

Repo organization

• Tutorials: Source code for the YouTube tutorials
• WIP: Half-baked crates that may have some useful code in the future
• docs: Various datasheets, books, and technical manuals
• submodules: All of the submodules for this repository.
  • referecnce projects: A huge collection of embedded Rust projects that I copy code from
• Data-Logger-PCB: KiCAD hardware designs for ESP32-C3 data logger PCB

Part 0: Remote Data Logger MVP

Minimum viable product project where we'll implement all the peripherals and features we need for the data logger

• 4 ADC's
• 16 Digital I/O
• DHT11
• SD card logging
• UART CLI Shell

Peripheral Tutorials

• p0-output: Make the "Hellow World" of embedded systems: a Blinky application to periodically turn an LED on and off
• p1-input: Add a button to turn the blinking logic on and off
• p2-threads: Move the button logic and LED logic to their own thread and pass messages between threads with crossbeams channel
• p3-adc: Read an analog-to-digital converter channel and print out the value
• p4-dht11: Read a DHT11 for temperature and humidity data
• p5-i2c: Configure and use a SX1509 GPIO Expander through I2C
• p6-spi: Write a string to a uSD card over SPI using embedded-sdmmc crate
• p7-uart: Receiver characters from the UART and send them back when we detect a carriage return

Application Tutorials

• [p8-cli-shell](): Create a simple CLI shell to interact with the ESP32-C3 over UART
• [p9-adc-stream](): Configure ADC's to continuously read and make that data available to other parts of the application through a mutex
• [p10-log-values](): Log all the values read from the ADC's
• [p11-digital-stream](): Continuously read the SX1509 inputs and log to SD card

Part 1:

For the next part of the project we will add in features listed below:

• Debugging
• Logging
• FSM/HSM
• Wifi
• MQTT
• OTA
• Pub/sub
• Crash dumps & diagnostics

Other features I'd like to add but don't have a clear example for yet:

• DMA
• Timer usage
