}— Supported ESP32 Architectures —
Core Pin Mapping
ESP32 GIOs are highly multiplexed but have limits (e.g. strapping pins, input-only pins like GPIO34-39). Embedino assigns only safe operational pins.
Multi-Core Support
Pin tasks to Core 0 or Core 1 safely using FreeRTOS primitives. The AI manages asynchronous resource locking automatically.
Cloud Compiler
Fast remote compilation creates `.bin` files automatically. Flash wirelessly via Web OTA or through standard WebUSB cables.
— FAQ —
Does Embedino support ESP-IDF alongside Arduino?
Yes. You can instruct the AI to generate code using the native Espressif IoT Development Framework (ESP-IDF) using C or write standard ESP32 Arduino sketch scripts.
How does WiFi and BLE setup work in the generator?
You can write prompts like "Host an access point named Home-ESP" or "Setup BLE with custom service UUID". The generator configures appropriate driver modules (`WiFi.h`, `BLEDevice.h`) and formats credential variables automatically.
What WebUSB browser options support direct ESP32 flashing?
Google Chrome, Microsoft Edge, and Opera support WebUSB. On connection, Embedino uses a browser-based esptool wrapper to directly access the ESP32 UART serial port and upload firmware binaries.
How does the AI handle GPIO constraints?
ESP32 has unique pin characteristics (e.g. GPIO 12 must not be high during boot, GPIO 34-39 are input-only ADC). Our planner validation engine filters available pins to guarantee your code matches actual hardware capability.
