BerryClip - 6 LED Board 是一个学习GPIO的开发板,适合我这样不懂硬件的童鞋,用python 控制6个LED灯,一个蜂鸣器,和一个开关
文档在这里

示例代码在这里

说实话,我的板子和这个颜色不一致。红色和绿色是反的。不过我觉得手头这个板子的颜色是对的
有几个很有趣的示例,如berryclip_12.py 是莫尔斯码
还有berryclip_cpu_01.sh 是用LED灯显示CPU占用
不过这个berryclip_cpu_01.sh是shell脚本,好像写错了一点,代码和注释不一致
# BerryClip LED reference : # LED 1 - Pin 7 - GPIO4 # LED 2 - Pin 11 - GPIO17 # LED 3 - Pin 15 - GPIO22 # LED 4 - Pin 19 - GPIO10 # LED 5 - Pin 21 - GPIO9 # LED 6 - Pin 23 - GPIO11 # #-------------------------------------- # Create array of GPIO references led[1]="11" led[2]="9" led[3]="10" led[4]="22" led[5]="17" led[6]="4"
但是LED灯是反的,应该是这样
led[1]="4" led[2]="17" led[3]="22" led[4]="10" led[5]="9" led[6]="11"
说是话shell脚本还是不如python脚本,所以修改了下,用来显示板子温度
温度的来源是 /sys/class/thermal/thermal_zone0/temp
#!/usr/bin/python # Import required libraries import RPi.GPIO as GPIO import time import string # Tell GPIO library to use GPIO references GPIO.setmode(GPIO.BCM) # List of LED GPIO numbers LedSeq = [4,17,22,10,9,11] # Set up the GPIO pins as outputs and set False print "Setup LED pins as outputs" for x in range(6): GPIO.setup(LedSeq[x], GPIO.OUT) GPIO.output(LedSeq[x], False) # 44925 -> 44 def getTemp(): f = open("/sys/class/thermal/thermal_zone0/temp") line = f.readline() f.close() rawTemp = string.atoi(line) return rawTemp / 1000 def resetAll(): for i in range(6): GPIO.output(LedSeq[i], False) # Light leds no def setLedNo(x): GPIO.output(LedSeq[x], True) time.sleep(0.2) while True: temp = getTemp() print temp resetAll() if(temp < 50): setLedNo(0) elif (temp < 55): setLedNo(1) elif (temp < 60): setLedNo(2) elif (temp < 65): setLedNo(3) elif (temp < 70): setLedNo(4) else : setLedNo(5) time.sleep(50) # Reset GPIO settings GPIO.cleanup()
50度以上每5度一个灯,从绿到黄到红
第一张图亮的是第2个LED灯,说明是在50-55度之间
samba 还是很方便的,可以直接在windows上用notepad++编辑树莓派上的python代码。不过安装方式和ubuntu略有不同
感谢这个
http://www.eeboard.com/bbs/forum.php?mod=viewthread&tid=5473
apt-get install samba samba-common-bin
注意啦,要安装samba-common-bin, 这点和ubuntu不同,否则sampassed无法使用
设置所有目录全部对root开放,编辑 /etc/samba/smb.conf
[global] netbios name = raspberry security = user [root] path=/ valid users=root public= yes browseable = yes writeable = yes
添加 samba 的 root用户
smbpasswd -a root
