20181015 4位数码管驱动

1.测试数码管

可通过此测试程序，调整数码管管脚。

from gpiozero import LEDBoard,Button
from time import sleep
from signal import pause
#from gpiozero.pins.pigpio import PiGPIOFactory

#factory = PiGPIOFactory(host='raspberry00.local')

#正向放置
DM = LEDBoard(19,11,12,20,21,13,7,16,active_high=False)#,pin_factory=factory)
PX = LEDBoard(26,6,5,8,active_high=True)#,pin_factory=factory)
#反向放置
#DM = LEDBoard(7,21,13,5,11,12,19,6,active_high=False)
#PX = LEDBoard(8,16,20,26,active_high=True)

while True :
    for px in PX:#轮流开启片选
        px.on()
        for dm in DM:#轮流开启段码
            dm.on()
            sleep(0.2)
        DM.off()
        #px.off()
    PX.off()
    sleep(1)

from gpiozero import LEDBoard,Button

from time import sleep

from signal import pause

#from gpiozero.pins.pigpio import PiGPIOFactory

#factory = PiGPIOFactory(host='raspberry00.local')

#正向放置

DM = LEDBoard(19,11,12,20,21,13,7,16,active_high=False)#,pin_factory=factory)

PX = LEDBoard(26,6,5,8,active_high=True)#,pin_factory=factory)

#反向放置

#DM = LEDBoard(7,21,13,5,11,12,19,6,active_high=False)

#PX = LEDBoard(8,16,20,26,active_high=True)

while True :

for px in PX:#轮流开启片选

px.on()

for dm in DM:#轮流开启段码

dm.on()

sleep(0.2)

DM.off()

#px.off()

PX.off()

sleep(1)

2、数码管字模程序

M7G= [
    (1,1,1,1,1,1,0,0),#0
    (0,1,1,0,0,0,0,0),#1
    (1,1,0,1,1,0,1,0),#2
    (1,1,1,1,0,0,1,0),#3
    (0,1,1,0,0,1,1,0),#4
    (1,0,1,1,0,1,1,0),#5
    (1,0,1,1,1,1,1,0),#6
    (1,1,1,0,0,0,0,0),#7
    (1,1,1,1,1,1,1,0),#8
    (1,1,1,1,0,1,1,0),#9
    (0,0,0,0,0,0,0,0),#全灭
    ]
