Everybody is good, now I have a card reader, IC card, have screen.
Now I want to use a serial port connection, read the card reader of the time, and can be modified, the computer (that is, to the current time input), the card reader time sometimes old wrong
Masters, can you help to solve, I have no idea now, it is better for code document. Thank you


The manufacturer provides equipment parameters: 9600, N, 8, 1

A little difficulty oh

Pick up points is king!

CodePudding user response:

PB operation the com is not very convenient, it is recommended that you use VC or ask people to help you with VC packaging good function to give you a call

CodePudding user response:

I use PB development of IC card, rf card program, as long as you are the foundation of knowledge, there is no any problem,
To fully understand and familiar with the factory to provide development kit, there are technical problems, direct contact with manufacturers of technical personnel, basically have done,

CodePudding user response:

Direct, don't need to ask in this looking for a manufacturer to DLL, OCX development such as the interface

CodePudding user response:

I find the original code, give a hint:
If should be displayed on the LCD screen: 0.5000000
The code is as follows:
displaydata=https://bbs.csdn.net/topics/char (128) + char (5) + char (0)//in this step is very important, to display the date, the date into the format
St=gnv_ic. Uf_disp8 (gi_device, 8, ref displaydata)//gnv_ic uf_disp8 is one of the manufacturers to provide dynamic library all functions encapsulated into a custom class,

CodePudding user response:

This simple question, manufacturers must have a DLL!

CodePudding user response:

No factory technical support is difficult to do,

CodePudding user response:

Contact with the manufacturer to DLL can be solved with pb contrived out efficiency is very low,

CodePudding user response:

Mscom32. Ocx can

CodePudding user response:

Whether manufacturers provide dynamic libraries provide function instead
