                             Sample Description
================================================================================
功能描述：
此样例演示了DMA从SRAM到SRAM传输数据的功能(SRAM和外设之间传输的样例请参考相关外设
样例工程)。

Function descriptions:
This example demonstrates the function of DMA transferring data from SRAM to
SRAM (please refer to the relevant peripheral sample project for the example
of transfer between SRAM and peripherals).

测试环境：
测试用板：PY32MD410_STK
MDK版本： 5.28
IAR版本： 9.20
GCC 版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: PY32MD410_STK
MDK Version: 5.28
IAR Version: 9.20
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行；
2. LED灯常亮，表明DMA传输完成并且数据正确；
3. LED灯闪烁，表明DMA传输出错或者DMA的数据传输的不正确。

Example execution steps:
1. compile and download the program to MCU and run it;
2. The LED light is constantly on, indicating that DMA transmission is complete
and the data is correct;
3. The LED light flashes, indicating an error in DMA transmission or incorrect
data transmission from DMA.
