🔨[bsp][stm32][driver][Improve the drivers within HAL_Driver]

you can use the STM32 board of you to finish this "good first issue"
if there's no board in "bsp/stm32/",
you can create the bsp with docuement How to make a STM32 BSP for RT-Thread.
Or you can try to finish the module as follow .

You can follow the document device introduce

可以用手上的STM32开发板来进行PR
如果没有BSP，可以尝试提交BSP
如果有BSP，可以尝试验证一些功能，有些BSP并不完善，并且PR，比如UART, SPI, IIC等模块，验证成功，应该有需要PR和修复的地方。

• 提交BSP开发板
• 提交SPI IIC CAN模块修复和验证
• i2c: 目前i2c 还没有和stm32的硬件I2C对接上rt-thread的驱动，添加drv_i2c.c
• STM32驱动对接输入捕获框架

根据文档：
驱动接口
STM32 BSP驱动文档
可验证模块，也可以添加utest测试项：

• PIN
• UARTV1
• UARTV2
• ADC
• DAC
• CAN
• HWTIMER
• IIC
• PWM
• RTC
• SPI
• WATCHDOG
• HWCRYPTO
• AUDIO IIS
• USBD
• USBH
• PULSE ENCODER
• WLAN
• ON-CHIP FLASH
•  STM32驱动对接输入捕获框架

Start by choosing one scoped item from the checklist, then read the STM32 BSP guide, the device introduction, and the driver-interface documentation; inspect the relevant BSP under bsp/stm32/. Done means one selected driver or module is implemented, repaired, or verified with a corresponding pull request, with a utest item added when applicable.
