如何从uint8_t类型的ctype指针访问javascript中的数据 [英] How to access the data in javascript from the ctype pointer of type uint8_t

问题描述

我在ctype uint8_t类型指针中有一些数据，我想将其读入javascript的var数组中。

I am having some data in ctype uint8_t type pointer which I want to read into the var array in javascript.

我已经做了简单的for循环来复制数据，

I have done simple for loop to copy the data,

for（var j = 0x00; j <5; j ++）{
var dataReceived [j] = ptr [j];
}

但是当尝试在警报窗口中显示数据时，它显示为未定义。

but when tried to display data in alert window, it is showing "undefined".

有人可以帮助我将ctype uint8_t指针中的数据复制到var数组吗？

Can anybody help me to copy data from ctype uint8_t pointer to var array?

有没有复制数据的机制？

Is there any mechanism to copy data?

推荐答案

我发现a的[contents]属性指针ctypes对象可用于访问其指向的对象。

I've found that [contents] property of a pointer ctypes object can be used to access the object it points to.

尝试以下操作：

for(var j = 0x00; j < 5; j ++) { 
    var dataReceived[j] = ptr[j].contents; 
}
