    Hello,

    I created an interface with buttons and comboBoxes and I want to modify the value of DATA [1] which is in the send.py file each time I press a button it assigns it the new value of DAT1 .

    I have defined the functions of BTN1, BTN2, BTN3 for the push buttons

    I want to have an idea how to code to have the desired result

    de3b91b3-acd1-4605-b7c4-4603b569e800-image.png

    This is the code of my 2 file Python :

    from PCANBasic import *
    from exemple import *

    DAT1=0b11111111

    #Initialize the PCAN

    m_PCAN = PCANBasic()

    m_Result = m_PCAN.Initialize(PCAN_USBBUS1, PCAN_BAUD_500K)

    #SEND DATA of ARD1

    #####################################ARD1#####################
    ARD1 = TPCANMsg()

    ARD1.ID = 0x461
    ARD1.LEN =8
    ARD1.DATA[0] = 0x07
    ARD1.DATA[1] = DAT1

    print(ARD1.DATA[1])

    ARD1.MSGTYPE = PCAN_MESSAGE_STANDARD

    m_Result = m_PCAN.Write(PCAN_USBBUS1,ARD1)

    if m_Result == PCAN_ERROR_OK :
    print("ARD1 Send")
    else:
    print("ARD1 Not Send")

    m_PCAN.Uninitialize(PCAN_USBBUS1)

    THE CODE OF MY file qt python

    from PyQt5 import QtCore, QtGui, QtWidgets
    from send import *

    class Ui_Form(object):
    def setupUi(self, Form):
    Form.setObjectName("Form")
    Form.resize(975, 603)
    self.pushButton = QtWidgets.QPushButton(Form)
    self.pushButton.setGeometry(QtCore.QRect(130, 110, 91, 21))
    self.pushButton.setObjectName("pushButton")

      Hi and welcome to devnet,

      First you should encapsulate your PCAN related code in a proper class so you can more easily use it from your GUI.

      Then what is DAT1 supposed to be as your slot parameter ?
