我正在用一个 PIC18 微控制器建立一个数据记录器, 用 C 来写代码 。
我要创建一个包含所有我记录过的数据的文件。 我当然要创建两个文件类型。 其中之一为. txt,另一个为. pqd( PQDIF 格式) 。
问题在于我无法在任何地方找到一个 txt 文件的结构。 我找到一个在 VB 中写成的 pqd 的 dll, 可以翻译为 C, 但很难, 所以我决定从比较简单的文件开始。
有谁知道我在哪里能找到 txt s 逻辑结构。 如果有的话, 你知道如何找到其他的文件类型结构吗?
对不起,任何英语错误。
There is no structure. Just use the Microchip Application Libraries and you re on your way: http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2680&dDocName=en547784
Here is the MDD section: http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2680&dDocName=en537999
What s more, they have existing demo applications for logging data from the analog-to-digital converter (ADC) to the text file on a regular basis. You can either purchase a $50 demo board to get up and running immediately, or you can order free sample PIC18 chips (chips and shipping are FREE), and build your own system on a solderless breadboard. http://www.microchip.com/samples/
我个人多次为PIC18、PIC24F和PIC32mx芯片的文本/CSV文件撰写了SD卡登录器。如果你在微芯片.com论坛中寻找用户“Dogbertius”的标签,你可以找到我的一些例子。
祝你好运!
文本文件只有使用编码意义上的格式(ASCII ,UTF-8 ,>>。 在ASCII,当然有
简单的文本文件只是 - 您为此应用程序正在写入的 C 源代码是纯文本, 例如, 您可以将普通文本文件装入任何编辑器, 例如编辑代码。 文本文件( font、 文本大小、 新行处理等) 的创建没有在文件中编码, 完全取决于显示数据的应用程序( 例如文本编辑器, 甚至 Windows/ DOS “ < a href=” ” http:// en.wikipe_ 28command% 29" rel= “ nofollow” type 命令 )。 以普通文本为基础的结构格式有:
PIC18可能不适合建立复杂的格式,你最好用专有的格式通过简单的原始数据,然后在个人电脑上处理这些数据,将其转换成你需要的任何东西。
