WebJan 4, 2024 · 因为缺少DSP2833x_CpuTimers.c而DSP2833x_CpuTimers.h存在(所有外设.h文件被DSP2833x_Device.h文件统一包含进了工程),导致.c中的一个结构体对象CpuTimer0只有.h中的extern声明却没有.c文件的定义来申请内存空间。这些问题进一步导致了工程编译不报错,但在链接时报错! WebCpuTimer0.InterruptCount++,相当于计算中断的次数。. //中断服务子程序. interrupt void cpu_timer0_isr (void) {. CpuTimer0.InterruptCount++; //用户可以在此处添加自己的代码, …
WebCpuTimer0.InterruptCount++这段代码是加在中断函数开头的,每进入一次中断,执行一次 CpuTimer0.InterruptCount++,相当于计算中断的次数。
WebCpuTimer0.RegsAddr->TIM.all. and . CpuTimer0.RegsAddr->TIM.half.LSW. I get the correct values the first time the program enters the ISR; after that, the watch window shows "Memory map prevented reading of target memory at 0x05810581@Data" I believe this is the reason why my variables have value 0. Still not sure how to solve it
