如标题所述，我试图创建两个独立的应用程序，一个是GUI/客户端，另一个是控制器/服务器。
GUI使用多个滑块从用户那里获取输入并通过套接字将值传输给控制器。
控制器接收数据并通过SPI连接将其传输到另一个外围设备。
程序传输第一个值然后崩溃。我得到的错误信息是这两个：
连接被对等方重置的错误和断开的管道错误。
GUI代码如下：
def Configure(e):
    Command(0, 0, ch0, reg_X, group_0, ch_0, 1)
def dacCommand(bus, dev, dacVar, command, dacGroup, dacChannel, multFac):
    Vref = 3
    offsetCode = 0x1555
    M = 65535
    C = 32768
    Iout = dacVar.get()
    Vout = Iout * multFac
    byte1 = command | dacGroup | dacChannel
    dacCode = math.ceil(Vout * (2**16) / (4 * Vref) + 4 * offsetCode)
    inputCode = math.floor((dacCode - C + (2**15)) * (2**16) / (M + 1))
    d = struct.pack('<H', inputCode)
    data = [0, 0, 0]
    dataCommand = [byte1, d[1], d[0]]
    byte1bin = f'{byte1:08b}'
    byte2bin = f'{d[1]:08b}'
    byte3bin = f'{d[0]:08b}'
    dataString = byte1bin + byte2bin + byte3bin
    client_socket.send(bytes(dataString, "utf-8"))
