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

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

class Ui_Form(object):

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 ?
