pip install dht11 现在python已经有了dht11的库,可以执行以下代码读取温湿度数据: importRPi.GPIOasGPIOimportdht11# initialize GPIOGPIO.setwarnings(False)GPIO.setmode(GPIO.BCM)GPIO.cleanup()# 端口一定要跟硬件连接匹配!# read data using pin 4instance=dht11.DHT11(pin=4)result=instance.read()ifresult....

从网上找到了DHT11厂家说明书,尝试用python根据时序图写数据获取驱动,但发现python的高层特性导致在做底层代码时例如控制20us时延这类需求就没什么好的办法。 还是得回到C-wiringPi 控制gpio 官网https://projects.drogon.net/raspberry-pi/wiringpi/ http://blog.csdn.net/xukai871105/article/details/17881433...
