如題,代碼如下：
$regfile = "attiny45.dat" '指定單片機型號
$crystal = 8000000 '指定頻率
$hwstack = 2
$swstack = 8
$framesize = 24
Config Portb = Output '定義B口為輸出
Config Portb.4 = Input '定義C.0口為輸入
Config Adc = Single , Prescaler = Auto , Reference = Avcc '配置AD轉(zhuǎn)換器
Enable Adc '使能AC轉(zhuǎn)換器
Dim Leddig(10) As Byte
Dim I As Word , P As Integer , V As Word , B As Word , N As Word , M As Word
Dim K As Single , G As Byte , S As Long , A As Word , C As Byte
Latch Alias Portb.1
Config Spi = Soft , Dout = Portb.3 , Ss = None , Clock = Portb.0
Restore Leddata '讀LED 顯示位碼（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
Start Adc
I = Getadc(2)
Stop Adc
A = I + A
Next
A = A / 64
S = A * 5000
K = S / 1023
A = K
A = A / 2 '設(shè)置最大量程為25V '
V = A / 1000 '千位
B = A / 100 '百位
N = A / 10 '十位
M = A Mod 10
Waitms 20
Spiinit '個位
P = M
Spiout Leddig(p + 1) , 1 '顯示個位
P = N
If N > 9 Then
P = P Mod 10
End If
Spiout Leddig(p + 1) , 1
P = B
If B > 9 Then
P = P Mod 10
End If
Spiout Leddig(p + 1) , 1 '顯示小數(shù)點
P = V
If V > 9 Then
P = P Mod 10
End If
Spiout Leddig(p + 1) , 1
Latch = 0 '使能顯示
Waitus 10
Latch = 1
Loop
Leddata: 'LED數(shù)字碼 (0-9)
Data &B00111111 , &B00000110 , &B01011011 , &B01001111 , &B01100110
Data &B01101101 , &B01111101 , &B00000111 , &B01111111 , &B01101111
注釋掉的恢復(fù)了，可以了
