 ===========================Steps for porting BM25S3221_1 Module to HT32 Starter Kit.===========================
 Step 1. Modify example_xxxxx\_ProjectConfig.ini.
         - Add DEVICE_NAME
         Example [take HT32F52352 as an example]:
           REM DEVICE_NAME
           REM ============================================================================
           52352

 Step 2. Modify example_xxxxx\ht32_board_config.h.
         - Add module communication interface pin setting
         Example [take HT32F52352 as an example]:

 ===========================Steps for porting BM25S3221_1 Module to Another Vendor's MCU.=======================
 Step 1. Unzip File:
         - Start by unzipping "BM25S3221_1_HT32_Vm.n.r.zip".

 Step 2. Port Source Code:
         - Migrate the src directory to your target project.
         Example: D:\<Another Vendor's MCU Target Project>\src

 Step 3. Include in Compilation:
         - Open the Keil project and make modifications as below.
         (Ensure "BM25S3221_1.c" and header files are included in your project's build list.)
         1. Add the module "Include Paths" to the project.
            Example: D:\<Another Vendor's MCU Target Project>\src
         2. Add the module "C language files" to the project.
            Example: BM25S3221_1.c

 Step 4. Modify Includes and APIs:
         - Use global search to identify and modify include files and APIs for porting.
         /*
           !!! PORTING !!!
           Description...
         */
         Note : Porting this module need to implement required APIs as below:
         -       API        :           Description         -
         ====================================================
         - BM25S3221_1_selSerial()  : Module UART communication interface pin change.
         - BM25S3221_1_Init()       : Module initialization using UART communication.
         - BM25S3221_1_writeBytes() : write data through UART.
         - BM25S3221_1_readBytes()  : read data through UART.
         - _BM25S3221_1_delay()     : delay ms.
