的确是没见过iar for STM32
-
祝朋友们花团似锦、香飘四溢，给力2011，展望2012。。。。。
-
刚用STM32做过485，没发现任何问题
-
我打开了，就是可慢了，好多东西都不知道在哪里了？？
-
不行啊 ，求高人指点！

获得硬盘序列号（原程序）
这是一个用端口对硬盘编程例子
本程序在必须在DOS下运行，我在qb4.5版本下运行通过
主板上共有两个IDE接口，每个接口上又分主、从，所以可以接4个IDE设备，这4个端口号各不同，本程序用端口1F0-1F7是主板上的第一个IDE接口上的主接口，最常用的就是这个了。别的只是端口号不一样，编程方法原理一样。
CODE: [Copy to clipboard]
--------------------------------------------------------------------------------
'获得硬盘序列号的程序（非逻辑盘卷标，有的把C盘的卷标说成是硬盘序列号）
'代码：QBASIC，运行环境：DOS
OUT &H1F6, &HA0
OUT &h1F2,1
OUT &H1F3, 1
OUT &h1F4,1
OUT &h1F5,1
OUT &H1F7, &HEC '获得硬盘信息的命令
DO WHILE flag &H58
f lag = INP(&H1F7)
if inkey$=chr$(27) then '如果按ESC键，终止程序
print "无法获得硬盘序列号"
end
end if
LOOP
re$ = SPACE$(18)
FOR i% = 1 TO 18
READ a$
H$ = CHR$(VAL("&H" + a$))
MID$(re$, i%, 1) = H$
NEXT i%
duan% = varSEG(re$):offe% = SADD(re$)
DEF SEG = duan%
print "本硬盘的序列号为 ";
FOR i = 1 TO 16
CALL Absolute(r%, offe%) '调用在qb中的内嵌汇编机器码
r1% = r% AND &HFF
r2% = (r% AND &HFF00) / &H100
IF i > 9 AND i < 15THEN PRINT CHR$(r1%); CHR$(r2%);
NEXT i
DEF SEG
END
'此DATA中的数据为机器码，用于读端口字数据（qb中的端口语句只能按字节读写端口，不能按字读写）
DATA 55,89,e5,ba,f0,01,ed,86,e0,8b,5e,06,89,07,5d,ca,02 ,00

顶ddd

keil仿真用得真不爽，我打算去买个板子，大家说是买开发板好还是学习版好呢？？给个意见，哈哈，谢啦
-
别51了，搞个大点的ARM7，有64个GPIO的那种~~~~~~~~~
嘿嘿。。。虽然那个了一点

何宗健的书不错。乐呵呵

4楼别误导啊...
WATCH可以观察局部变量. 只是局部变量一般保存在寄存器中, 如果一个局部变量的操作完了, 寄存器装载别的东西去了. 局部变量就看不到了. 不如全局变量在静态变量区容易观察.

我想自己画一个slider 控件
先是贴一幅划槽 的图片，然后再贴一幅滑块的图片，但怎么让滑块的图片放在划槽 图片的上面,而不被遮挡？

这样肯定不成鉴定完毕。

谢了兄弟，就是这个！

汇编调用C语言；C语言调用汇编一般都是用R0、R1、R2、R3来传参的。第一个参数放R0，第二个参数R1，第三个参数R2，第四个参数R3。
