我是靠谱客的博主欣慰西牛，这篇文章主要介绍MATLAB-DSP官方例程------ADC触发PWMMATLAB C2000----- 例程（二）------ADC触发PWM，现在分享给大家，希望可以做个参考。

MATLAB C2000----- 例程（二）------ADC触发PWM

官方例程链接如下：MATLAB

一.模型

在这里插入图片描述
总系统由两哥子系统组成一个中断触发一个ADC-PWM

ADC-PWM系统

ADC触发pwm并且adc的输出为pwm的duty的输入，且为五倍关系。

二.烧入过程

与上篇文章相似

三.代码分析

我们先看一下所生成的文件

如红框所示这些为所生成的文件

c2807x_2837xx_adcpwmasynctest_ert_data.c

主要定义了数据的大小
c2807x_2837xx_adcpwmasynctest_ert.c

初始化PWM和ADC 以及模型所使用的函数以及结构体
c2837xDBoard_Realtime_Support.c

一些常用型的库函数
c2837xDSchedulerTimer0.c

就是跟求解器步长相关的函数,如果加入积分模块很有可能就在这里运算。
ert_main.c

主函数

初始化外设
MW_c28xGlobalInterrupts.c
MW_c28xGPIO.c
MW_c28xx_adc.c
MW_c28xx_board.c
MW_c28xx_csl.c
MW_c28xx_pwm.c
MW_c28xx_xbar.c

profiler_Support.c // 可能为调试文件暂未尝试（看大佬这样说的）

ert_main.c
