如题,代码如下：

$framesize = 24                              
Config Portb = Output                           '定义B口为输出

Config Adc = Single , Prescaler = Auto , Reference = Avcc   '配置AD转换器

Dim I As Word , P As Integer , V As Word , B As Word , N As Word , M As Word

Config Spi = Soft , Dout = Portb.3 , Ss = None , Clock = Portb.0
Restore Leddata                               '读LED 显示位码（0-9）
For P = 1 To 10
   Read Leddig(p)
Next
Do
A = 0
C = 1
For C = 1 To 64                               '取64次adc的平均值

     If N > 9 Then
     P = P Mod 10
     End If
   Spiout Leddig(p + 1) , 1

注释掉的恢复了，可以了

呵呵~~~行不通啊

把求平均计算给注释掉了

Sorry，求平均的注释掉了，取消注释就好了
