I use the MPC5744P chip，and install the freemaster sofware. Now，it can already communicate normally.But, i want to go further and use its active-X function. I use the example of user Manual about html.When I press the button, the interface will display an error message.Please help me to analyse . It would be better if you could provide a usable html routine.
look into the installed FreeMASTER Communication Driver (FreeMASTER Communication Driver) example for ActiveX access from Excel. The default path to the example is: c:\NXP\FreeMASTER_Serial_Communication_Driver_V2.0\examples\ActiveX_examples\Excel\freemaster_excel.xlsm
Thank you very much for your reply.Attachment is my project file.Please help analyze the cause of the error.
I want to change the value of the variable when I press the button.But I have tried it failed a few times.I hope you can provide the routine.Looking forward to your reply.
