2. 新项目开始
- File -> New Project -> Pure Python -> Create ….
- File -> Settings –> Project: xxx ->Project Interpreter
- project interpreter: python 3.6 (3.6.6)
click ‘+” -> click Manage Repositories click ‘+’ 镜像源
以下选择一个即可：
初始：
https://pypi.python.org/simple
国内：
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
阿里云 http://mirrors.aliyun.com/pypi/simple/
豆瓣(douban) http://pypi.douban.com/simple/
然后 click ‘刷新按钮’ 然后 。。。。 搜索“pyserial” 然后click Install Package
坑：不知为何国内的源没法安装成功
3. 串口基本操作
pyserial库常用函数：
serial = serial.Serial('COM1', 115200) #打开COM1并设置波特率为115200，COM1只适用于Windows
serial = serial.Serial('/dev/ttyS0', 115200) #打开/dev/ttyS0并设置波特率为115200, 只适用于Linux
print(serial.portstr) #能看到第一个串口的标识
serial.write("hello") #往串口里面写数据
serial .close() #关闭serial 表示的串口
serial .open() #打开串口
data = serial .read(num) # 读num个字符
data = serial .readline() #读一行数据，以/n结束，要是没有/n就一直读，阻塞。
serial .baudrate = 9600 # 设置波特率
print serial #可查看当前串口的状态信息
serial.isOpen() #当前串口是否已经打开
serial.inWaiting() #判断当前接收的数据
serial.flushInput() # 清除输入缓冲区数据
serial.flushOutput() #中止当前输出并清除输出缓冲区数据
# utf-8
import serial
import serial.tools.list_ports
port_list = list(serial.tools.list_ports.comports())
print(port_list)
if len(port_list) == 0:
print("无可用串口！")
else:
for i in range(0, len(port_list)):
print(port_list[i])
try:
portx = "COM1" # 端口：CNU； Linux上的/dev /ttyUSB0等； windows上的COM3等
bps = 115200
# 超时设置，None：永远等待操作；
# 0：立即返回请求结果；
# 其他：等待超时时间（单位为秒）
timex = 5
ser = serial.Serial(portx, bps, timeout=timex) # 打开串口，并得到串口对象
print("串口详情参数：", ser)
result = ser.write("hello world !\r\n".encode("gbk")) # 写数据
print("写总字节数：", result)
# # 十六进制的发送
# result = ser.write(chr(0x06).encode("utf-8")) # 写数据
# print("写总字节数：", result)
#
# 十六进制的读取
# print(ser.read().hex()+"\r\n") # 读一个字节
ser.close() # 关闭串口
except Exception as e:
print("error!", e)
# BIF build in funciton 内置函数
# 逐渐割掉瑕疵，才能产生卓越体验
# print("test\r\n" * 8)
