1.树莓派UART端口的位置 TXD位于HEAD-8 RXD位于HEAD-10 GND位于HEAD-6(可选其他GND) 2.树莓派的TXD应接USB转串口设备的RXD,当然如果测试失败请交换RXD和TXD的顺序 3.经过很多次的测试(N>25),当波特率为115200时打开树莓派的UART时,树莓派会莫名其妙的发送一字节0xF8,该问题始终无法解决。不过波特率为9600时并...
sudoapt-get install python-serial 1. 3、输入phthon3启动python IDE。 4、创建serial实例ser,端口为 ‘/dev/ttyAMA0’,波特率设置为115200bps,第三个为校验位,可以不写。 >>> import serial >>> ser = serial.Serial(’/dev/ttyAMA0’,115200) 5、检验串口是否打开,若未打开则输入 ser.open() 打开 >...
在Raspberry Pi上使用UART之前,我们应该配置并启用它。 GPS模块 电路连接图 GPS模块与Raspberry Pi连接 例 让我们用Raspberry Pi连接GPS模块,并提取GPS信息。我们可以使用Python和C(WiringPi)将GPS模块连接到Raspberry Pi。要连接GPS模块,请将GPS模块连接到Raspberry Pi,如上图所示。 使用Python语法 让我们使用Python从...

4.) It is possible to test the function of the on-board uart (and of the USB ports with serial converters too) with a simple terminal program for example Minicom. No needs to write a Python script for this job. I've used for my tests Realterm on my PC connected via an simpe USB-...
