鸿蒙系统怎么查询iccid？

public static String getDeviceId() {

// 通过设备管理的获得设备列表方法获得

List<DeviceInfo> deviceList = DeviceManagergetDeviceList(DeviceInfoFLAG_GET_ONLINE_DEVICE);

// 判空

if (deviceListisEmpty()) {

return null;

}

// 获得设备数量

int deviceNum = deviceListsize();

// 创建两个列表，分别存设备id和设备名

ArrayList<String> deviceIds = new ArrayList<>(deviceNum);

ArrayList<String> deviceNames = new ArrayList<>(deviceNum);

// 遍历设备列表，将设备id和设备名分别存到两个列表中

deviceListforEach(device -> {

deviceIdsadd(devicegetDeviceId());

deviceNamesadd(devicegetDeviceName());

});

// 我就直接使用deviceIds的第一个元素，作为启动远程设备的目标id

String deviceIdStr = deviceIdsget(0);

return deviceIdStr;

}

是的，就是编译器选择。

参考以下内容

Compiler name and version macros are predefined by all C/C++

compilers to enable #if/#endif sets around compiler-specific code,

such as inline assembly, compiler-specific intrinsics, or special language

features This can be necessary in high-performance code that aims at using the

best performance tricks available for each compiler This article

surveys common compilers and shows how to use predefined macros to detect the

compiler name and version at compile time

How to detect the compiler name

Compiler name macros indicate a specific compiler, such as Intel ICC or

Microsoft Visual Studio There are exceptions See the notes after the

table

#if defined(__clang__)

/ Clang/LLVM ---------------------------------------------- /

#elif defined(__ICC) || defined(__INTEL_COMPILER)

/ Intel ICC/ICPC ------------------------------------------ /

#elif defined(__GNUC__) || defined(__GNUG__)

/ GNU GCC/G++ --------------------------------------------- /

#elif defined(__HP_cc) || defined(__HP_aCC)

/ Hewlett-Packard C/aC++ ---------------------------------- /

#elif defined(__IBMC__) || defined(__IBMCPP__)

/ IBM XL C/C++ -------------------------------------------- /

#elif defined(_MSC_VER)

/ Microsoft Visual Studio --------------------------------- /

#elif defined(__PGI)

/ Portland Group PGCC/PGCPP ------------------------------- /

#elif defined(__SUNPRO_C) || defined(__SUNPRO_CC)

/ Oracle Solaris Studio ----------------------------------- /

#endif

With iccex

lngSize = LenB(iccex)

lngICC = ICC_USEREX_CLASSES

End With

这个循环导致慢的，应该加个条件以退出循环

改为以下程序自己验证吧，是PB0输出LED，PC0输入，是吧？？？？

//ICC-AVR application builder : 2012/11/18 13:39:36// Target : M128

// Crystal: 40000Mhz

#include <iom128vh>

#include <macrosh>

#define uchar unsigned char

#pragma interrupt_handler int1:2

void int1(void)

{

EIMSK=0X00;

PORTB = 0x01;

EIMSK=0X01;

}

void main()

{

int1(); //PB0为上拉电阻

DDRB = 0xff;

PORTB = 0x00;//PBO为低电平，LED不亮

DDRC=0X00;//C口最后输入端

DDRC=0XFF;

while(1)

{

if((PINA & BIT(0))==0) //判断是否PA0口按下键了。

{PORTC |=BIT(0);} //亮

else

{PORTC &=~BIT(0);} //灭

}

}
