But it's worth the effort if you will use it for more projects.And it comes with support for serial ports (QSerialPort class) out of the box, so you won't have to deal with the native API calls. A potential downside is that you have to program in C++, which has its own rather steep learning curve.

I didn't know it had the serial port class -- I'll be able to use that within the next month, if it has the features I need. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

It did not have the feature to ask how many bytes in the send-buffer. Only in case you like to switch the direction of RS485. .-) Olaf

Been using it for a couple of months and I just love it! VERY powerful! If you know C++, I wouldn't say it's difficult to learn how to use - just perhaps a little time-consuming. And the documentation IS excellent. -- Randy Yates Digital Signal Labs http://www.digitalsignallabs.com

I am still undecided, but I think I will try the C# way since it appears rather easy and since I don't need a multi platform solution and I won't spend too much time on it, hopefully. Qt seems interessant also, I know C++ and I will look into that, as a second choice.

It's good to know there's serial port support built in now. I remember we had to find a separate serial qclass for a small Qt project back in 2011.

I've written assembly for a half dozen processors, C, C++, C#, Python, Perl, VHDL, Verilog, three flavors of BASIC, Java, Javascript, and Awk, and in all that have NEVER encountered a language so unlikely to give you the results you want without extensive debugging as when my EDA tools force me to write Tcl. -- Rob Gaddi, Highland Technology -- www.highlandtechnology.com Email address domain is currently out of order.

If you want to use Tk, use Python, or Scheme, or sticks and rocks. _Anything_ but TCL. -- Grant Edwards grant.b.edwards Yow! ... I have read the at INSTRUCTIONS ... gmail.com
