推荐答案
我需要验证用户选项.
I need to verify the user option.
要求用户按一个键并验证其是否有效.
Ask the user to press a key and verify if it was valid.
Again:
mov ah, 00h ; BIOS.GetKeyboardKey
int 16h ; -> AX
cmp al, "0"
jb Again
cmp al, "7"
ja Again
用户在此处进行了0到7的有效选择.现在，将此选择转换为背景色.记住输入仍然是字符！转换后，将其放入属性字节的高半字节，以用于输出到屏幕.
Here the user has made a valid selection from 0 to 7. Now turn this choice into a background color. Remember the input is still a character! Once converted, you put it into the high nibble of the attribute byte to be used for outputting to the screen.
sub al, "0" ; Convert from character to value (*)
mov cl, 4
shl al, cl ; Shift into high nibble (background color)
add al, 15 ; Add in low nibble (foreground color)
mov bh, al
您的屏幕截图使用红色文本颜色，但是如果用户选择红色backgroundcolor，那将使文本消失.因此，我建议您使用BrightWhite(15)作为前景色.
(*)在这种特殊情况下可以省略(因为随之而来的是左移)
Your screenshot uses the red text color, but that would make the text disappear if the user selected the red backgroundcolor. That's why I suggest you use BrightWhite (15) as your foreground color.
(*) can be omitted in this particular case (because of the shift left that follows)
我想使用用户选项将LED的颜色从(0-7)更改
I want to change the leds color from (0-7) using the user option,
通常的方法是使用BH寄存器中设置的属性简单地重绘整个彩色图块.
The usual way would be to simply redraw the whole colored tile using the attribute set up in the BH register.
首先，您需要使用BIOS.ScrollWindowUp 和AL=0来清除磁贴！
First you clear the tile using BIOS.ScrollWindowUp with AL=0 !
FirstButtonCol db 10
FirstButtonRow db 15
FirstButtonWidth db 10
FirstButtonHeight db 3
frase1 db 'LED1', '$'
...
mov ch, FirstButtonRow
mov cl, FirstButtonCol
mov dh, ch
add dh, FirstButtonHeight
dec dh
mov dl, cl
add dl, FirstButtonWidth
dec dl
mov ax, 0600h ; BIOS.ScrollWindowUp AL=0
int 10h
然后将光标置于按钮上方并写上标签"LED1"
Then you position the cursor over the button and write the label "LED1"
lea si, [frase1]
mov cx, 1 ; ReplicationCount
mov bh, 0 ; DisplayPage
mov dl, FirstButtonCol
mov dh, FirstButtonRow
add dx, 0102h
NextChar:
mov ah, 02h ; BIOS.SetCursor
int 10h
mov al, [si]
mov ah, 0Ah ; BIOS.WriteCharacter
int 10h
inc dl ; Next column
inc si ; Next char
cmp byte [si], "$"
jne NextChar
