我正在尝试向计算机发送一个文本数组。我使用CP2102模块PIC18F47 K40、XC8 V1.44和RealMt1,数字1、2和7和8在计算机屏幕上显示,但是数组3456不显示。我做错什么了?

有趣的是,但是目前“卡拉克特”的定义是不可见的,如果你把“2线”缩写成什么样子呢?
以上来自于百度翻译 以下为原文 Funny thing. But currently the definition of 'karakter' is invisible. And what happens if you abbreviate the "2-liner" to TX1REG = text[n];? |

K40 PICS在访问const数据方面有一个已知的问题。XC8的最新版本包含一个解决方案,但是您必须手动激活它。
以上来自于百度翻译 以下为原文 The K40 PICs have a known problem with accessing const data. The latest versions of XC8 contain a workaround for it, but you have to manually activate it. Have a look at http://www.microchip.com/forums/m969418.aspx |
