CCS通过breakpoint读入主机文件的问题

comeback
Expert 1795 points


我看到CCS的教程上讲通过设置断点，然后改变断点的action属性，选择“read data from file”，可以从主机文件向程序的buffer输入数据。我试了教程上的例子，的确可行。我的问题是，输入文件的格式是什么？我打开例子附带的文件，sine.dat，看到第一行有一串数字"1651 1 0 0 0"，我想知道这些是什么意思。如果我自己要构造输入文件，应该怎么写。

    你好：

    Code Composer data file

    A text file that contains one line of header information and stores the data as one sample per line. The memory data can be in any of these formats:

    Hexadecimal

    Integer

    Long

    Float

    The header information for data files uses this syntax:

    MagicNumber  Format StartingAddress PageNum Length

    MagicNumber—fixed at 1651.

    Format—a number from 1 to 4, indicating the format of the samples in the file.

    This number represents a data format: (1) hexadecimal, (2) integer, (3) long, or (4) float.

    StartingAddress—starting address of the block that was saved.

    PageNum—page number the block was taken from.

    Length—number of samples in the block.
