PSOC5不能使用浮点数字

下面是一个例子。



     以下为原文
  Here is an example.
   

还将堆设置为CydWr文件中的0x0200。



     以下为原文
  Also set the heap to 0x0200 in the .cydwr file.

谢谢Bobgar，但是那个例子不起作用。我得到两个错误和一个警告：
生成错误：未定义的引用“ftoA”，未定义的引用“LCDApPRSKY”（我认为应该是LCDA PrimtScript（））
警告：赋值使指针没有整数
打印一个浮子到LCD只是我更大问题的一个简单例子，我不能使用浮标。是否有编译器开关或其他缺少的东西？我的例子，编译和运行，但双浮不显示。在我真正的项目我使用atof()将字符串转换为浮点数，但结果都是0。我只是试着印刷浮发现它不工作，并出现浮不支持。
我认为答案是沿着迪马斯响应这线条：http://www.cypress.com/forum/known-problems-and-solutions/how-can-i-use-function-sprintf-psoc-designerbut我没能想出来。我的目录不包含local.mk所以我创建和addedcodecompressor：= $（codecompressor）- lfpm8c，但它仍然不工作。



     以下为原文
  Thanks bobgoar, but that example doesn't work. I get two errors and one warning:
       Build errors: undefined reference to 'ftoa', undefined reference to 'LCD_PrString' (should be LCD_PrintString(), I think)
       Warning: assignment makes pointer from integer without a cast
    Printing a float to the LCD was just a simple example of my larger problem that I can't use floats. Is there a compiler switch or something else I'm missing? My example compiles and runs, but the float and double are not displayed. In my real project I use atof() to convert a string to float, but the result is always 0. I tried just printing a float and found that it didn't work, and it appears the float is not supported.
    I think the answer is along the lines of dimas response here: http://www.cypress.com/forum/known-problems-and-solutions/how-can-i-use-function-sprintf-psoc-designer but I haven't been able to figure it out yet. My directory did not contain a local.mk so I created on and added CODECOMPRESSOR:=$(CODECOMPRESSOR) -lfpm8c, but it still doesn't work.

也可以做这些设置。



     以下为原文
  
    Make these settings also.
   
   

谢谢鲍勃，我疯狂的改变了，仍然没有任何东西…



     以下为原文
  Thanks bobgoar, I mad those changes and still nothing...

我将尝试你的程序在PSoC 5LP，因为我没有你的设备，这是100针版本。我来看看我得到了什么。



     以下为原文
          I am going to try your program on a PSOC 5lp as I don't have your device which is the 100 pin version. I will see what I get.   

这是你的程序，它运行良好。只需将设备更改为项目中的设备，然后将设备更改为设备选择器。原来你需要0x800堆，因为0x200不够大。享受你的计划。

  Here is your program and it is working fine. Just change the device back to your device in project and then device selector.  Turns out that you need 0x800 heap as 0x200 is not big enough. enjoy your program.

我也改变了LCD端口同意我的设置。你使用了P2（6:0），我用了P2（7:1），这就是我的电路板是如何布线的。



     以下为原文
  I also changed the lcd port to agree with my setup. You used P2(6:0) and I used P2(7:1) as that is how my board is wired .

这是LCD的图片。

谢谢您！现在开始工作了。谢谢你抽出时间来帮助我，树立榜样！

  Thank you! It is working now. Thanks for taking the time to help me and build the example!
