最近在看TC275各模块的时钟配置,用户手册里关于时钟产生和分配读懂了大概,有下面几个问题希望各位大神帮小弟解答,非常感谢 1、我看手册里说频率最大的时钟作为fsourse,即fsourse=fmax,那么这个fsourse是哪里产生的? 2、手册里有个各模块之间的时钟频率关系表,但不知道从哪开始设定,一般各模块时钟设定的顺序是什么,希望给我点提示,让我知道应该在哪里看也行 3、如果不进行各模块时钟配置,系统是不工作还是按默认时钟运行

f_source有两个部分,其实在我的帖子“TC275调试日志——最小系统设计:时钟分析”里面有贴图。是在f_PLL和f_back中作出选择。一个是PLL时钟,正常配置为200MHz; 另一个是默认进入的备用时钟源back时钟100MHz。(我没有单独写出来,稍后会加上)。至于其他各个模块时钟怎么分配,会在下一个帖子说明。最近因为有点事,一直没更新。。。

1、外部晶振来的
2、后期有一本MCAL的书,书中以Tom为例有很详细的介绍
3、需要初始化及使能的,不然工作不了

外部晶振20MHz,由PLL锁相环配置CPU主频,其他频率参考EB指导手册。

我是个新手别笑我啊,下面这段程序是流水灯实验的主函数,在里面没有找到时钟配置的相关函数,时钟配置是在哪里完成的?#include "CpuStdIfx_Types.h"
#include "CpuStdIfxCpu_Intrinsics.h"
#include "ScuStdIfxScuWdt.h"
#include "DemoApp.h"
int core0_main (void)
{
__enable ();
/*
* !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!!
* Enable the watchdog in the demo if it is required and also service the watchdog periodically
* */
IfxScuWdt_disableCpuWatchdog (IfxScuWdt_getCpuWatchdogPassword ());
IfxScuWdt_disableSafetyWatchdog (IfxScuWdt_getSafetyWatchdogPassword ());
GPIO_Demo_init();
while (1)
{
GPIO_Demo();
}
return (1);
}

其实在你主函数执行之前,首先执行的是启动文件。时钟配置函数就是在启动文件里调用的,启动文件的位置在:BaseFramework_TC27xB_GPIO_Src4_McHalTricoreCpuCStartIfxCpu_CStart0.c 你可以找找看
