您好，我在PIC18F14K50上使用EEPROM有问题。我想输入0x01到0x00地址eeprom。然后，我希望从UART得到这个结果。我只得到“eeprom数据是0”。如果您有什么想法解决这个问题，请告诉我。我期待着您的回音。

1.37只是最新版本之前的一个。它不包括外围库，如果您在docs文件夹中阅读Readme_XC8.htm文件，您会看到这些库。包含它们的最后一个版本是1.34。您可以获得它们，但是如前所述，这是一个单独的下载。
以上来自于百度翻译 以下为原文 1.37 is only one before the latest version. It does NOT include the peripheral libraries, which you would see if you read the Readme_XC8.htm file in the docs folder. The last version to include them was 1.34. You can get them, but as already stated, it is a seperate download. |

@qhb谢谢你的回答。我下载了v1.37XC8并使用它。但是，我无法正确地获取数据。我在项目的Properties上选择了XC8 v1.37并运行我的程序。我试着运行稍微修改过的程序。此源代码如下。>/**文件：newmain.c*Author：newmain.c*newmain.c*Author：kashiharaakira**创建于2016年8月31日，2016年8月31日，8：35PM**//\8：早8：35PM*/包含<*xc.h>包括<<<&xc.h>包括

如果这是你已经使用的版本，你为什么又下载它？“外围库”是从您下载编译器的同一个网页上单独下载的。这些内容都在我建议您阅读的自述文件中进行了解释。您使用的格式说明符是错误的。它将试图显示一个不可打印的字符。尝试“%d”或“%x”，而不是“%c”。
以上来自于百度翻译 以下为原文 Why did you download it again, if that is the version you were already using? The "peripheral libraries" are a seperate download, from the same web page where you download the compiler. This is all explained in the readme file I advised you to read. You're using the wrong format specifier there. It will be trying to show a non-printable character. Try "%d" or "%x" instead of "%c". |

谢谢你的回复。我写错了。我下载了v1.34XC8并尝试了。但是，我没能正确地获得数据。我试图在从%c更改为%d之后获得数据，但是我得到了以下结果。eeprom_read是0我选择v1.34XC8作为项目文件的属性。这个操作正确吗？DarioGIs，我真的应该尝试使用GPIO吗？
以上来自于百度翻译 以下为原文 Hello Thank you for your reply. @qhb I'm sorry. I take a mistake to write here. I download v1.34 XC8 and try it. However, I was not able to get correctly data. I tried to get data after changing from %c to %d but I get the following. eeprom_read is 0 I selected v1.34 XC8 on properties of my project file. This operation is correctly? @DarioG Is it true that I should try to output used GPIO? |
