用Simulink开发F2812,SCI 或者SPI 通讯没输出，有大大做通过的吗？ [复制链接]

        用Matlab里面的links and target 里面的TC2000的工具包进行DSP开发，PWM，GPIO，ADC都能顺利的开发和调试，但是串口通讯一直调试不通，无论是SCI还是SPI都不行，程序没问题，能编译能下载到DSP里面，比如我做的自己收发的小范例，程序运行后，用串口线和PC机连接起来，用串口调试助手向DSP发送数据，但是收不到DSP返回的数据，SCI不通SPI也不通，因为是新手，没用过CCS直接编写程序开发的方式，一直使用Simulink开发的方式，所以对.c文件也不太清楚，个位大大帮我看看啊，生成的.c看看有什么问题，谢谢了.....

 * example code indicates where these should take place relative to executing

 * the generated code step function.  Overrun behavior should be tailored to

 * your application needs.  This example simply sets an error status in the

 * real-time model and returns from rt_OneStep.

对了 DSP 开发板用的是瑞泰的F2812-A
