我们设置两个Raspberry Pi GPIO引脚作为输出(BCM25/BOARD22和BCM23/BOARD16),建立与DHT22传感器的连接,然后我们循环几个条件语句来检查所处环境是否满足公认的“适于计算的最佳湿度和温度条件”。 每当湿度或温度超出范围时,_humidity_led或_temperature_led都会亮起。但它也可以用于驱动电路,例如IRLZ24NMOSFET或继电器...

You can only use one convention in each project, so choose one and stick to it. Neither convention is "right", so go with whichever one makes most sense to you. It is worth noting however, that certain peripherals rely on GPIO/BCM numbering. For this article, we will stick toBOARDnumbe...
With GPIO17, 22 and 27 following on from each other with little thought to logical numbering. The BCM pin mapping refers to the GPIO pins that have been directly connected to the System on a Chip (SoC) of the Raspberry Pi. In essence we have direct links to the brain of our Pi to ...
RaspberryPi的GPIO中断编程 http://.yunyoubar/邮件群发 树莓派的GPIO引脚不仅可以输出高低电平,也可以当做输入端口(可以想象成键盘输入),当GPIO接入的是 高电平,GPIO的值可以认为是1,如果是低电平则是0。如下图所示,可以使用一个PushButton开关按键来 控制GPIO25(BCMNumbering)的高低电平以达到控制的目的。 GPIO25...
Webiopi,Python, 使用BCM GPIO编号 WiringPi-Go, Go语言,支持以上三种编号 编号规范 第一列是wiringPi API中的缺省编号,wiringPiSetup()采用这列编号 第二列(Name)往往是转接板的编号 第三列是树莓派板子上的自然编号(左边引脚为1-15,右边引脚为2-26),RPi.GPIO.setmode(GPIO.BOARD)采用这列编号 ...
Figure 6.Pin numbering in the header BCM number.This refers to the Broadcom channel number, which is the numbering inside the chip that is used on the Raspberry Pi. WiringPi number.WiringPiis the underlying framework used by Pi4J (which I use as the library in the Java project) to contro...

Raspberry Pi 1 (Revision 2) Pinout The second revision of the Pi 1 has a slight change to its GPIO pinout. This change was a result of a modification made to the Raspberry Pi’s CPU. The BCM Numbering for the I2C pins changed from 0 and 1 to 2 and 3. All newer versions of the...
