### 3.2 SPI Bus
This board doesn't support Arduino SPI header file and functions.
The SPI bus of the Nucleo board is the `CS/D10`, `MOSI/D11`, `MISO/D12` and `SCK/D13` pins printed on the board. These `D11`, `D12` and `D13` pins It is taken over by the RT-Thread SPI device framework and there is no need to directly control these pins. User needs to operate `D10` chip select pin. Directly quote `#include <SPI.h>` (Arduino official SPI header file) to use. After using the SPI function, the PWM function of `D10` and `D11` will be irreversibly disabled and converted to the SPI function.

### 3.2 SPI总线
目前本BSP不支持使用Arduino的SPI功能。
Nucleo板的SPI总线是板上丝印的 `CS/D10`、`MOSI/D11`、`MISO/D12` 以及 `SCK/D13` 引脚，这`D11`、`D12` 以及 `D13` 引脚是被RT-Thread SPI设备框架接管的，不需要直接操控这些引脚。用户需要操作 `D10` 片选引脚。直接引用`#include <SPI.h>`（Arduino官方SPI头文件）即可使用。在使用SPI功能后，`D10` 和 `D11` 的PWM功能将会不可逆失效，转为SPI功能。
