## 1 RTduino - Arduino Ecosystem Compatibility Layer for RT-Thread
|
|
|
|
STM32F410 Nucleo board has support [RTduino](https://github.com/RTduino/RTduino). Users can use Arduino APIs, third party libraries and programming method to program on the board.
|
|
|
|
### 1.1 How to Enable RTduino
|
|
|
|
Please go to the [RTduino repository](https://github.com/RTduino/RTduino) to see the details.
|
|
|
|
```Kconfig

# 2 Arduino Pinout
|
|
|
|
|
|
|
|
This board complies with Arduino UNO pins layout. For more details, please take a look at: [pins_arduino.c](pins_arduino.c) and [pins_arduino.h](pins_arduino.h).

> Notice:
|
|
>
|
|
> 1. Don't use a same hardware timer to drive PWM (analogRead) and servos at same time, because hardware timers can only generate a same frequency for 4 PWM channels. Otherwise, it could cause a failure when drive servos.

## 3 Communication
|
|
|
|
### 3.1 I2C Bus
|
|
|
|
I2C bus is `SCL/D15` and `SDA/D14` pins. Users can directly include the `#include <Wire.h>`, which is the Arduino official I2C header file, to use the I2C bus.
|
|
|
|
### 3.2 SPI Bus
|
|
|
|
This board doesn't support Arduino SPI header file and functions.
|
|
|
|
### 3.3 Serial
|
|
|
|
This board supports to use `Serial.` method to operate `uart2` device. See [example](https://github.com/RTduino/RTduino/blob/master/examples/Basic/helloworld.cpp).
