Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/travisjneuman/.claude --skill embedded-iot- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads embedded-iot automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Embedded Systems & IoT
Microcontroller Platforms
| Platform | Best For | Language | IDE |
|---|---|---|---|
| ESP32 | WiFi/BLE IoT devices | C/C++, MicroPython | PlatformIO, Arduino IDE |
| STM32 | Industrial, real-time | C/C++ | STM32CubeIDE, PlatformIO |
| Arduino | Prototyping, learning | C++ (Arduino) | Arduino IDE, PlatformIO |
| Raspberry Pi Pico | RP2040, dual-core | C/C++, MicroPython | Thonny, VS Code |
| nRF52 | BLE-focused IoT | C, Zephyr | nRF Connect SDK |
Firmware Patterns
GPIO & Peripherals
// ESP-IDF GPIO example
gpio_config_t io_conf = {
.pin_bit_mask = (1ULL << GPIO_NUM_2),
.mode = GPIO_MODE_OUTPUT,
.pull_up_en = GPIO_PULLUP_DISABLE,
.pull_down_en = GPIO_PULLDOWN_DISABLE,
.intr_type = GPIO_INTR_DISABLE,
};
gpio_config(&io_conf);
gpio_set_level(GPIO_NUM_2, 1);
I2C Communication
// Read sensor via I2C
i2c_cmd_handle_t cmd = i2c_cmd_link_create();
i2c_master_start(cmd);
i2c_master_write_byte(cmd, (SENSOR_ADDR << 1) | I2C_MASTER_WRITE, true);
i2c_master_write_byte(cmd, REG_TEMP, true);
i2c_master_start(cmd);
i2c_master_write_byte(cmd, (SENSOR_ADDR << 1) | I2C_MASTER_READ, true);
i2c_master_read(cmd, data, 2, I2C_MASTER_LAST_NACK);
i2c_master_stop(cmd);
i2c_master_cmd_begin(I2C_NUM_0, cmd, pdMS_TO_TICKS(1000));
i2c_cmd_link_delete(cmd);
RTOS (FreeRTOS)
// Task creation
void sensor_task(void *pvParameters) {
while (1) {
float temp = read_temperature();
xQueueSend(data_queue, &temp, portMAX_DELAY);
vTaskDelay(pdMS_TO_TICKS(1000));
}
}
xTaskCreate(sensor_task, "sensor", 4096, NULL, 5, NULL);
// Mutex for shared resources
SemaphoreHandle_t spi_mutex = xSemaphoreCreateMutex();
if (xSemaphoreTake(spi_mutex, pdMS_TO_TICKS(100)) == pdTRUE) {
spi_transfer(data);
xSemaphoreGive(spi_mutex);
}
IoT Protocols
MQTT
// ESP-IDF MQTT client
esp_mqtt_client_config_t mqtt_cfg = {
.broker.address.uri = "mqtt://broker.hivemq.com",
};
esp_mqtt_client_handle_t client = esp_mqtt_client_init(&mqtt_cfg);
esp_mqtt_client_start(client);
esp_mqtt_client_publish(client, "/sensors/temp", "23.5", 0, 1, 0);
Key IoT Protocols
| Protocol | Transport | Use Case |
|---|---|---|
| MQTT | TCP/TLS | Pub/sub messaging, telemetry |
| CoAP | UDP/DTLS | Constrained devices, REST-like |
| BLE | Radio | Short-range, low power |
| LoRaWAN | Radio | Long-range, low data rate |
| Matter | IP | Smart home interoperability |
Best Practices
- Power management: Deep sleep modes, wake-on-interrupt, duty cycling
- Watchdog timers: Always enable, reset periodically, catch firmware hangs
- OTA updates: Dual partition scheme, rollback on boot failure, signature verification
- Memory: Static allocation preferred, avoid heap fragmentation, use memory pools
- Testing: Hardware-in-the-loop (HIL), mock hardware interfaces for unit tests
FAQ
What does the embedded-iot skill do?
Embedded systems firmware, microcontrollers (ESP32, STM32, Arduino, Raspberry Pi), RTOS (FreeRTOS, Zephyr), IoT protocols (MQTT, CoAP, BLE), bare-metal C/C++, and hardware peripheral interfaces (I2C, SPI, UART, GPIO). Use when developing firmware, working with microcontrollers, or building IoT devices.
How do I install embedded-iot?
Run npx skills add https://github.com/travisjneuman/.claude --skill embedded-iot in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/embedded-iot/ (personal) or .claude/skills/embedded-iot/ (project).
Which AI agents can use embedded-iot?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is embedded-iot safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains embedded-iot?
It is published by travisjneuman in travisjneuman/.claude. It has 195 recorded installs.
