yuskegoto/esp32c3_rust_getting_started

What is this?

• Getting start project for ESP32-C3 Rust hosted at TDA.
• This project is mainly referenced from Tai Hideaki san's rust-esp32-osc-led project.
• For the instruction plase see TDA's workshop notion page

Projects

• examples/button.rs
  • Button input example
• examples/button_led.rs
  • Serial LED example
• examples/connect_wifi.rs
  • Wifi connect example
• examples/osc_send.rs
  • OSC send example
• examples/main.rs
  • OSC receive and led control

Before running wifi related projects, export wifi credentials and port no.

export OSC_WIFI_SSID=LAB3
export OSC_WIFI_PASS=aabbccddeeff
export OSC_WIFI_RECV_PORT_STR=5000
export OSC_WIFI_RECV_PONG_STR=5001

# osc send port
export OSC_WIFI_SEND_PORT_STR=5100
# osc destination (PC) port
export OSC_WIFI_DEST_PORT_STR=5101
export OSC_WIFI_DEST_IP=192.168.2.100

Commands

source ~/export-esp.sh  # if needed
cargo run               # build & flash & monitor
cargo build --example button
cargo run --example connect_wifi
espmonitor /dev/ttyACM0

Crate

• rosc is used to encode/decode OSC packet
• smart-leds trait and its implementation ws2812-esp32-rmt-driver are used to control LEDs

Samples

• Wifi connect sequence for esp_idf_svc 0.46
• Tai Hideaki san's rust-esp32-osc-led

OSC test with OSCD

• Commandline OSC tester. You can also use other tools like TouchDesigner.
• With another terminal, run oscd to send OSC packet (IP should be your device's IP and PORT should be OSC_WIFI_RECV_PORT)

cargo install oscd
oscd

Following OSC commands are available

/ping       # reply /pong 1 to your_ip:OSC_WIFI_PONG_PORT from your device
/rgb r g b  # set color to LED (int 0-255 are available for r, g, b)
