npm i -g iot-container
Usage
iot-container [--sudo] [--device <path>]
Example
# This does cd into current working directory
iot-container --device /dev/ttyUSB0
idf.py create-project my_project
cd my_project
cat <<EOF > main/my_project.c
#include <stdio.h>
#include <freertos/FreeRTOS.h>
#include <freertos/task.h>
void app_main () {
while (1) {
printf("Hello World!\n");
vTaskDelay(1000 / portTICK_PERIOD_MS);
}
}
EOF
# Optional configs
# idf.py menuconfig
idf.py build
idf.py -p /dev/ttyUSB0 -b 921600 flash
idf.py -p /dev/ttyUSB0 monitor # CTRL-] to exit
USB permission
For rootless, the permanent way is to only allow the logged-in user via ACL:
udev_rule='KERNEL=="ttyUSB[0-9]*", TAG+="udev-acl", TAG+="uaccess"'
echo "$udev_rule" | sudo tee /etc/udev/rules.d/60-extra-acl.rules
sudo udevadm control --reload-rules
sudo udevadm trigger
A temporal solution is to change the USB permission:
sudo chmod 660 /dev/ttyUSB0
Otherwise, use --sudo
.
Arduino
Strictly use those versions:
- ESP-IDF
5.1.4
- Arduino-ESP32
3.0.1
iot-container --build-arg "ESP_IDF_VERSION=5.1.4"
idf.py create-project my_sketch
cd my_sketch
# Add the Arduino ESP32 component
git clone -b 3.0.1 --depth=1 https://github.com/espressif/arduino-esp32.git components/arduino-esp32
# Delete the default .c file because Arduino uses .cpp
rm main/my_sketch.c
# Change the CMakeLists.txt configuration
sed -i 's/SRCS "my_sketch.c"/SRCS "my_sketch.cpp"/' main/CMakeLists.txt
cat <<EOF > main/my_sketch.cpp
#include "Arduino.h"
void setup () {
Serial.begin(115200);
}
void loop () {
Serial.println("Hello world with Arduino API!");
delay(1000);
}
EOF
# (or use the menuconfig)
cat <<EOF > sdkconfig.defaults
CONFIG_AUTOSTART_ARDUINO=y
CONFIG_FREERTOS_HZ=1000
