+# STM32U575-NUCLEO开发板的Arduino生态兼容说明
+
+## 1 RTduino - RT-Thread的Arduino生态兼容层
+
+STM32U575-NUCLEO开发板已经完整适配了[RTduino软件包](https://github.com/RTduino/RTduino)，即RT-Thread的Arduino生态兼容层。用户可以按照Arduino的编程习惯来操作该BSP，并且可以使用大量Arduino社区丰富的库，是对RT-Thread生态的极大增强。更多信息，请参见[RTduino软件包说明文档](https://github.com/RTduino/RTduino)。
+
+### 1.1 如何开启针对本BSP的Arduino生态兼容层
+
+Env 工具下敲入 menuconfig 命令，或者 RT-Thread Studio IDE 下选择 RT-Thread Settings：
+
+```Kconfig
+Hardware Drivers Config --->
+    Onboard Peripheral Drivers --->
+        [*] Compatible with Arduino Ecosystem (RTduino)
+```
+
+## 2 Arduino引脚排布
+
+该BSP遵照Arduino UNO板的引脚排列方式，并扩展增加了STM32U575-NUCLEO自身的板载资源功能引脚。详见 `pins_arduino.c`
+
+更多引脚布局相关信息参见 [pins_arduino.c](pins_arduino.c) 和 [pins_arduino.h](pins_arduino.h)。

+  *
+  *   This file provides two functions and one global variable to be called from
+  *   user application:
+  *      - SystemInit(): This function is called at startup just after reset and
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32u5xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  *   After each device reset the MSI (4 MHz) is used as system clock source.
+  *   Then SystemInit() function is called, in "startup_stm32u5xx.s" file, to
+  *   configure the system clock before to branch to main program.
+  *
+  *   This file configures the system clock as follows:

+  * @brief  Update SystemCoreClock variable according to Clock Register Values.
+  *         The SystemCoreClock variable contains the core clock (HCLK), it can
+  *         be used by the user application to setup the SysTick timer or configure
+  *         other parameters.
+  *
+  * @note   Each time the core clock (HCLK) changes, this function must be called
+  *         to update SystemCoreClock variable value. Otherwise, any configuration
+  *         based on this variable will be incorrect.
+  *
+  * @note   - The system frequency computed by this function is not the real
+  *           frequency in the chip. It is calculated based on the predefined
+  *           constant and the selected clock source:
+  *
+  *           - If SYSCLK source is MSI, SystemCoreClock will contain the MSI_VALUE(*)
+  *
+  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(**)
+  *
+  *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(***)
+  *
+  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(***)
+  *             or HSI_VALUE(*) or MSI_VALUE(*) multiplied/divided by the PLL factors.
+  *
+  *         (*) MSI_VALUE is a constant defined in stm32u5xx_hal.h file (default value
+  *             4 MHz) but the real value may vary depending on the variations
+  *             in voltage and temperature.
+  *
+  *         (**) HSI_VALUE is a constant defined in stm32u5xx_hal.h file (default value
+  *              16 MHz) but the real value may vary depending on the variations
+  *              in voltage and temperature.
+  *
+  *         (***) HSE_VALUE is a constant defined in stm32u5xx_hal.h file (default value
+  *              8 MHz), user has to ensure that HSE_VALUE is same as the real
+  *              frequency of the crystal used. Otherwise, this function may
+  *              have wrong result.
+  *
+  *         - The result of this function could be not correct when using fractional
+  *           value for HSE crystal.
