STM8汇编程序错误没有解决方法

你好！
 
 
 事实上，而不是：
 LDW（{MyVect-MyData}，Y），X
 你必须写
 LDW（{{MyVect-MyData} + {$ ram1_segment_start- $ ram0_segment_start}}，Y），X
 
 ram1_segment_start和ram0_segment_start在mapping.inc中定义。
 
 ram1_segment_start是定义MyVect的段的十六进制格式的起始地址。
 
 ram0_segment_start是定义MyData的段的十六进制格式的起始地址。
 
 它在发行说明（第3个解决方法）中进行了解释

Hello!


In fact, instead of:
LDW     ({MyVect-MyData},Y),X
you have to write
LDW     ({{MyVect-MyData}+{$ram1_segment_start-$ram0_segment_start}},Y),X

ram1_segment_start and ram0_segment_start are defined in mapping.inc.

ram1_segment_start is the start address in hexadecimal format of the segment where MyVect is defined.

ram0_segment_start is the start address in hexadecimal format of the segment where MyData is defined.

It is explained in the release notes (3rd workaround)

罗伯特，
 
 我感谢你的帮助（和耐心......）！

Robert,

I thank you for your help (and patience...)!

你好，
 
 
 更一般地，如果段起始地址在另一个文件中定义，则两个段中的两个标签之间的差异不起作用。
 为避免这种情况，请计算同一段内的差异，并使用常量计算段起始地址之间的差异。
 例如，通过这种方式：
 STM8 /
 
 #include''mapping.inc''
 
 段'ram0'
 BYTES
 ram0_start
 ram0_data DS $ B7
 ram0_var DS 1
 
 段'ram1'
 话
 ram1_start
 ram1_data DS $ AB6
 ram1_var DS 1
 
 细分'rom'
 主要
 LDW X，＃{ram1_var-ram0_var};不，不行
 LDW X，＃{{ram1_var-ram1_start} - {ram0_var-ram0_start} + {$ ram1_segment_start- $ ram0_segment_start}};好
 JRA *
 
 细分'vectit'
 dc.l {$ 82000000 + main};重启
 
 结束
 
 其中ram0_segment_start和ram1_segment_start是mapping.inc中定义的常量：
 #define ram0_segment_start 0
 #define ram1_segment_start 100
 
 和
 
 其中段'ram0'和'ram1'在mapping.asm中定义：
 BYTES
 ram0_segment_start-ram0_segment_end'ramm0'处的段字节
 话
 ram1_segment_start-ram1_segment_end'ram1'处的段字节
 
 抱歉给你带来不便。

Hello,


More generally, differences between two labels in two segments don't work if the segment start addresses are defined in another file.
To avoid this, compute differences within the same segment and use constants to compute the difference between segment start addresses.
For example, in this way:
stm8/

     #include ''mapping.inc''

     segment 'ram0'
     BYTES
ram0_start
ram0_data    DS  $B7
ram0_var     DS  1

     segment 'ram1'
     WORDS
ram1_start
ram1_data   DS  $AB6
ram1_var    DS  1

     segment 'rom'
main
     LDW     X,#{ram1_var-ram0_var} ; no, doesn't work
     LDW     X,#{{ram1_var-ram1_start}-{ram0_var-ram0_start}+{$ram1_segment_start-$ram0_segment_start}} ; ok         
     JRA     *

     segment 'vectit'
     dc.l {$82000000+main}                                    ; reset

     end

where ram0_segment_start and ram1_segment_start are constants defined in mapping.inc:
     #define ram0_segment_start 0
     #define ram1_segment_start 100

and

where segments 'ram0' and 'ram1' are defined in mapping.asm:
     BYTES
     segment byte at ram0_segment_start-ram0_segment_end 'ram0'
     WORDS
     segment byte at ram1_segment_start-ram1_segment_end 'ram1'

Sorry for the inconvenience.
