Python实现的BeagleBone Black 串口助手（全部源码）

继续昨天的工作，又开发了一个串口调试助手。

偷懒了，没有用面向对象，把之前的代码修改了一下，直接放在BBB 如图

源码如下：

__author__ = 'fuchunyang111@163.com'
from tkinter import *
import serial
from tkinter import ttk
import time
import threading
import Adafruit_BBIO.UART as UART
def Choice(event):
context = boxValue.get()
list = ['COM1']
def Submit(data):
if ser.isOpen() == True:
n = ser.write(data)
print(data)
else:
show00.delete(0.0,END)
show00['background'] = "red"
show00.insert(0.0,'Open serial first!')
def serial_read():
while 1:
if ser.isOpen() == True:
data = ser.read(1)
text2.insert(0.0,data)
#print("11")
#time.sleep(0.00006)
time.sleep(0.006)
def open():
if ser.isOpen() != True:
ser.open()
print("uart1 opening")
if ser.isOpen() == True:
lab2['background'] = "green"
button2['text'] = 'Close serial'
button2['command'] = close
show00.delete(0.0,END)
show00['background'] = "white"
show00.insert(0.0,'Serial opened!')
print("uart1 opened")
else:
lab2['background'] = "red"
show00.delete(0.0,END)
show00['background'] = "red"
show00.insert(0.0,'Serial error!')
def close():
ser.close()
if ser.isOpen() == False:
lab2['background'] = "black"
button2['text'] = 'Open serial'
button2['command'] = open
show00.delete(0.0,END)
show00['background'] = "white"
show00.insert(0.0,'Serial closed!')
def txd():
data = text1.get(0.0,END)
data = data[::-1]
Submit(data.encode())
def clear1():
text1.delete(0.0,END)
def clear2():
text2.delete(0.0,END)

root = Tk()
root.title("BBB_Serial Test")
root.geometry("580x400")
w = Canvas(root,width = 580,height = 400,background = "#4169E1")
w.pack()
w.create_line(25,45,550,45,fill = 'black',width = 3) # top直线
#串口设置相关变量

lab1.place(x = 10,y = 10)
#串口号选择下拉菜单
boxValue = StringVar()
boxChoice = ttk.Combobox(root,textvariable = boxValue,state = 'readonly',width = 6)
boxChoice['value'] = ('COM1')
boxChoice.current(0)
boxChoice.bind('<<ComboboxSelected>>',Choice)
boxChoice.place(x = 80,y = 10)
#串口开启按钿
button2 = Button(root,text = 'Open serial',command = open)
button2.place(x = 150,y = 5)
#串口状态指示
lab2 = Label(root,text = '

lab2.place(x

#消息提示框

text2.place(x = 70,y = 30*3+10 )
#发送，清空按钮
