应该等于uint32_t getCrc(void)
{
uint32_t expectedCrc = *(uint32_t*)0x27FF0;
return expectedCrc;
}
但是令人惊讶的是,该值为:expectedCrc
我尝试定义一个指向0xECD8743D
的指针,并为其分配内存地址,如下所示:
0x82828282
但是指针本身的值为uint32_t
,而uint32_t getCrc(void)
{
uint32_t *ptr = (uint32_t*)0x27FF0;
uint32_t expectedCrc = *ptr;
return expectedCrc;
}
等于0xFFFF
我在不同的内存地址中找到了这两个值:
我也尝试过使用expectedCrc
进行相同操作,但是它给出了相同的值。
最后,我尝试使用0x82828282
检查此控制器中指向char的指针的大小,答案是char *ptr = (char*)0x27FF0
,它等于uint8_t size = sizeof(char*);
。
我认为这与24位内存地址和CPU架构有关。我正在使用0xb0
控制器。
有人可以解释为什么会这样吗?
更新
我尝试用176
替换地址stm8
,它工作正常。所以问题出在长地址。我想在最后一个地址中写入CRC值,以避免在程序变大时用代码本身覆盖它。我该如何处理?
答案 0 :(得分:5)
来自Cosmic编译器数据表https://www.cosmic-software.com/pdf/cxstm8_pd.pdf
cxstm8根据应用程序的大小提供2种不同的内存模型。
对于小于64k的应用程序,“第0节”内存模型通过默认函数调用和2字节指针来提供最佳代码密度。
对于大于64k的应用程序,标准内存模型为轻松使用线性寻址空间提供了最佳的灵活性。每个模型都带有自己的一组库。
这可能是导致您出现问题的原因。如果要直接访问16位以上地址的内存位置,则需要使用正确的内存模型。
答案 1 :(得分:2)
@Raje回答说这与内存模型有关,我在 COSMIC用户指南中做了进一步的阅读,发现以下内容:
STM8编译器支持两种应用程序内存模型 大于64K,让您选择最有效的行为 取决于您的处理器配置和应用程序。所有 这些模型允许代码大于64K,然后起作用 指针默认为@far指针(3个字节)。数据指针是 除非使用明确声明,否则默认为@near指针(2个字节) @far修饰符。
因此,解决方案是将scanner
添加到指针的类型如下:
@far
问题解决了。
