其中.sect "ramfuncs"语句的作用就是就把用汇编写的函数DSP28x_usDelay定位在ramfuncs段。 2、在工程中添加源文件DSP2833x_MemCopy.c,该文件中的函数void MemCopy(Uint16 *SourceAddr, Uint16* SourceEndAddr, Uint16* DestAddr),实现把你想复制的代码从装载地址RamfuncsLoadStart—RamfuncsLoadEnd拷贝...
GPIO_setHigh(myGpio, GPIO_Number_3); // DELAY_US(5000000); } } 楼主程序是跑在FLASH 中还是RAM中?如果是跑在FLASH中的话,要调用以下函数,将DELAY_US();函数搬到RAM里运行,否则PC跳到RAM里去执行DELAY_US()时,由于你没有把DELAY_US()搬到RAM里,因此相当于PC跑飞掉(现象和你描述的一样)。...
LOAD_ START(_RamfuncsRunStart)令编译器创建了一个变量RamfuncsRunStart,该变量指向段ramfuncs的运行地址的首地址(LOAD_ START为编译伪指令,请见CCS的帮助文档); 从第1和2行可以看出,段“ramfuncs”中的函数DSP28x_usDelay()的装载地址和运行地址是不同的,本程序中装载在Flash的块FLASHD中,而在SARAM L0中运行...
1TI的DELAY_US(A) 函数,为什么是延迟A us?#define DELAY_US(A) DSP28x_usDelay(((long double) A * 1000.0L) / (long double)CPU_RATE) - 9.0L) / 5.0L) 2TI的DELAY_US(A) 函数,为什么是延迟A us?#define DELAY_US(A) DSP28x_usDelay(((long double) A * 1000.0L) / (long double...
)和毫秒级delay_ms()。1.普通延时法这个比较简单，让单片机做一些无关紧要的工作来打发时间，经常用循环来实现，不过要做的比较精准还是要下一番功夫。下面的代码是在网上搜到的，经测试延时比较精准。//粗延时函数，微秒 void delay_us(u16 time){ u16 i=0;while(time--){ i=10; //自己定义...
The US government has urged the European Commission to delay the implementation of the EU's deforestation regulation (EUDR), which is due to come into force from 30 December. "We are deeply concerned with the remaining uncertainty and the short time frame to address the signi...

To construct a zero-skew gated-clock tree, let us again assume that we are given an abstract topology. The tasks here are to embed the internal nodes and to determine where buffers and clock gates should be inserted. We will now describe an adaptation and simplification of the approaches des...
