前言 python
例如：Python 的设计具有很强的可读性，相比其他语言经常使用英文关键字，其他语言的一些标点符号，它具有比其他语言更有特色语法结构。易于学习、易于阅读、易于维护、具有可移植、可扩展等特性。
一、云台的主要用途？
示例：云台用于相机的稳定器，起到平衡与稳定作用。云台的应用范围很广，各种特殊行业也对云台产品有一定的需求。
二、代码实现步骤
下面就是实现所有功能的代码！
代码如下（示例）：
class Mywindow(QtWidgets.QWidget, Ui_MainWindow):
# QtCore.QMetaObject.connectSlotsByName(Ui_MainWindow)
def init(self,):
super(Mywindow, self).init()
self.setupUi(self)
self.init()
self.setWindowTitle(“云台控制器”)
self.ser = serial.Serial()
self.port_check()
self.level_angel = 0
self.vertical_angle = 0
self.speed_data()
self.horizontalSlider.valueChanged.connect(self.valuechange)
self.horizontalSlider_2.valueChanged.connect(self.valuechange)
self.horizontalSlider.valueChanged.connect(self.va1)
self.horizontalSlider_2.valueChanged.connect(self.va2)
def init(self):
# self.status = self.statusbar
# self.status.showMessage('时间：', 1000)
# 串口检测
self.detected__button_1.clicked.connect(self.port_check)
# 串口显示
self.s1__box_8.currentTextChanged.connect(self.port_imf)
# 打开串口
self.open_button.clicked.connect(self.port_open)
# 关闭串口
self.close_button.clicked.connect(self.port_close)
# 定时器接收数据
self.timer = QTimer(self)
# self.timer.timeout.connect(self.data_receive)
# 按键控制动作
self.a_button.clicked.connect(self.data_send_a)
self.w_button.clicked.connect(self.data_send_w)
self.s_button.clicked.connect(self.data_send_s)
self.d_button.clicked.connect(self.data_send_d)
self.x_button.clicked.connect(self.data_send_x)
self.q_button.clicked.connect(self.data_send_q)
self.e_button.clicked.connect(self.data_send_e)
self.z_button.clicked.connect(self.data_send_z)
self.c_button.clicked.connect(self.data_send_c)
# 云台信息返回
self.inquire1_button.clicked.connect(self.send_level_angel)
self.inquire2_button.clicked.connect(self.send_vertical_angle)
# 角度控制
self.level_button.clicked.connect(self.send_leve)
