Question: Is there a simple way for serial input?

I fiddled around with your amazing simavr a bit and learnt that you could see the serial output of a simulation:

However I wonder if there is also a simple way for serial input to the simulation. It seems not to be connected to stdin...

Well, the easiest way would be to run your firmware into the 'simduino' example, as it has a way of forking a 'real' terminal and redirect the serial port in/out there (via a PTY)...

Also, you can try the simutron - a GUI wrapper for simavr, where you can just to draw your test circuit, drag the UART - PTY link component, and that's it.

@hovercraft-github I'm trying to use your simulator on Ubuntu x64 but I'm not getting it. It looks like the lib: libQt5Widgets.so.5 is missing Already Installed: qt5-default cutecom gtkwave Would you like to make the x64 version available?

ricardojlrufino commented 7 years ago

@hovercraft-github I can compile, by running the build unix script, please update the HELP by putting this guide.

hovercraft-github commented 7 years ago

@ricardojlrufino : Thank you for your interest. I will create wiki page about compiling soon. Could you please report in more details, do you successfully compile it and what problems besides lack of help you met. BTW you will be probably the first who built it on the 64 bit platform :)

Also the trunk version contains more plugins, namely hd44780 and pcd8544 LCD and pushbutton which are not yet in the build script.

The problem I had was to apply the "PATCH" of ARVSIM as explained in the README. I could only compile through the script. And its working,

I think it's interesting to launch the x64 version, as I think most use it.

hovercraft-github commented 7 years ago

This is because readme outdated - this patch is already applied in the simavr master branch. Also several hours ago some other changes made which can (maybe) help in your case, so I would advise you to get fresh simavr sources and recompile it. This may make simavr less restrictive with respect to the target MCU address range.
