c - 如何在 IAR IDE Watch 窗口中通过指针显示数组范围？

Question

在 IAR Embedded Workbench 中，我有一个指向内存缓冲区的指针。观看指针时，我可以看到它所指向的单词的内容。我如何告诉 Watch View 列出缓冲区的范围，从指针开始，对于某些指定长度的元素？

例如，输入表达式:

myPtr[0..2]

将显示相当于三个表达式的信息:

myPtr[0]
myPtr[1]
myPtr[2]

来自 Iar Embedded Workbench (9.20) 帮助:

In windows where you can edit the Expression field and in the Quick Watch window, you can specify the number of elements to be displayed in the field by adding a semicolon followed by an integer. For example, to display only the three first elements of an array named myArray, or three elements in sequence starting with the element pointed to by a pointer, write:

myArray;3

To display three elements pointed to by myPtr, myPtr+1, and myPtr+2, write:

myPtr;3

Optionally, add a comma and another integer that specifies which element to start with. For example, to display elements 10–14, write:

myArray;5,10

To display myPtr+10, myPtr+11, myPtr+12, myPtr+13, and myPtr+14, write:

myPtr;5,10
