Flow control mode on GLK12232-25SM

thrust · Post by **thrust** » Sat Apr 13, 2002 3:40 am

Hi!

I can connect and send data to my GLK12232-25SM using visual c++. (Using CreateFile, WriteFile) But the display generates unpredictably results when the buffer is full so therefore i suppose the flow control mode would be the apropriate solution.

Any one have some source describing how to do this? I guess it will involve some overlapped communication, but im not sure how to do this.

Any help would be appreciated,

The bit in the manual describe how to use flow control pretty well... though if you're really stuck give mat-d-rat a bell, he put it in LCDC.

Cheers,

As Cheese says, in the manual there are control codes yo usend to turn on/off flow control - but you must rememebr to do that on the com side too. I just change a couple of parameters on the comport control I use so I can't really help any more than that.

Here is some C source code...

Hi again!

The problem is not really how the commands on the diplay works, rather how to implement it under Win32.

I have something that almost works using overlapped communication and a thread that waits for signals from the display. The problem is the reading thread behaves okay in debug-mode but produces really strange results in release-mode. Another problem is that the reading thread takes almost all processor cycles. Any help on how to solve this would be apreciated.

Thanks in advance,
