I have recently installed MS Visual Studio 2015 with the Arduino plugin "Visual Micro".
Everything works fine, upload a sketch etc. Except when I try to compile my code when I use FreeRTOS. I downloaded the FreeRTOS libary through the Arduino IDE (library manager). Therefore(in MS VS 2015) I could chose to include the library in MS VS 2015. So I included the library in one of my sketches. Below you see my code example. Within the Arduino IDE i can compile the code and upload it to the device, but in MS VS there are some errors.

At the end of this post you will find the short snippet of the compilers error log. Maybe someone already came around the same issue and has a quick fix.
An example debugger breakpoint has been created. To switch the demo
breakpoint off, deselect Visual Micro>Tutorial Mode.

If you read the error messages, the issue is explained clearly.
include Arduino_FreeRTOS.h must appear first.
Your example shows it included last.
Put it first and the errors will go away.
Arduino_FreeRTOS.h includes many definitions that are used in other places, hence the need for it to be first.
Unrelated to your question, but using delay() is nasty as it consumes CPU cycles needlessly. Try vTaskDelay() as alternative which defers (or blocks) to the Scheduler to unblock other Tasks or run the idle Task which is the Arduino loop() function.
The loop() function can then put the CPU to sleep, reducing power consumption. See the feilipu.me post on topic for more.
vTaskDelay() counts Ticks, so hence the need to divide by the Tick period in milliseconds. i.e.
Time in ms / portTICK_PERIOD_MS = Ticks

Found the issue, the includes where in the wrong order: dont know why;).
You cant only include freeRTOS in MS VS you need to correct the order of the includes by yourself.
Here is the correct order:
#include <Arduino_FreeRTOS.h>
#include <croutine.h>
#include <event_groups.h>
#include <FreeRTOSConfig.h>
#include <FreeRTOSVariant.h>
#include <list.h>
#include <mpu_wrappers.h>

#include <portmacro.h>
#include <projdefs.h>
#include <queue.h>
#include <semphr.h>
#include <StackMacros.h>
#include <task.h>
#include <timers.h>
I'm not sure about the Arduino code you are referring to, but normally there is no reason to include FreeRTOSConfig.h directly - instead include FreeRTOS.h first, and that will get the ordering of the port layer files and FreeRTOSConfig.h files correct for you, then include the header files that contain the API functions you want to use.

I'm trying hard to get a list of style properties for a GtkWidget (GtkButton). This is my code so far:
#include <gtk/gtk.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main (int argc, char *argv[])
{
// Declare variables.
GtkWidget *btn = gtk_button_new();
guint *count = {0};
GParamSpec **list = NULL;
// Initialize gtk.
gtk_init(&argc, &argv);
// Get style properties.
list = gtk_widget_class_list_style_properties(GTK_WIDGET_CLASS(btn), count);
// Exit cleanly.
exit(EXIT_SUCCESS);
}
I get a clean compile with:
gcc -o gtk_test gtk_test.c `pkg-config --cflags --libs gtk+-3.0`
But I get the following errors when run:
(process:72182): Gtk-CRITICAL **: 10:42:23.167: _gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed

(process:72182): Gtk-CRITICAL **: 10:42:23.167: _gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed
Segmentation fault
I don't think I'm doing it right, but I can't find any examples that use gtk_widget_class_list_style_properties that I understand. They ones I do find use klass and the first argument. But I can never find where klass is declared or even what it is.
Can someone please help point me in the right direction? I went to the gtk website and did a search on GTK_WIDGET_CLASS and it came back with nothing! Very frustrating to say the least.
What am I supposed to use for the GTK_WIDGET_CLASS argument that will return the style properties for a GtkButton?
I tried out your sample code. Actually, it looks like you just have the incorrect macro. Instead of:
GTK_WIDGET_CLASS(btn)
try:
GTK_WIDGET_GET_CLASS(btn)
I tried that and then received no critical messages.
Regards.

Can you help me, please? I have installed latest Adafruit SSD1306. Or is there another library for work with this display? Noone example I found and tried worked for me
Adafruit has stated the following:
It will compile if you set the processor to digispark pro.
Why it is that way is known to them.
EDIT: The problem was solved - New problem TwoWire does not name a type. Solution for that:
The adafruit library is directly referencing the TwoWire class which is normally defined in wire.h. For the Digistump boards, they have a similar class but it is called WUI_TWI, not TwoWire.
Probably the easiest way to fix this would be to modify the wire.h file that came from Digistump. add this near the end of the file wire.h
extern USI_TWI Wire;
#define TwoWire USI_TWI // add this line
#endif
The wire.h file (in windows) will be located in
C:\Users\YOUR_USERNAME\AppData\Local\Arduino15\packages\digistump\hardware\avr\1.6.7\libraries\Wire
make sure it is this one for digistump with the USI_TWI class, not the standard arduino one with the TwoWire class
I am trying to use only aes in my program. I have copied the files
config.h
aes.h
havege.h
to the folder polarssl. But when I run the program
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "polarssl/aes.h"
#include "polarssl/havege.h"
int main()
{
char buff[2][64] = {"ABCDEFGHIJKLMN", ""};
havege_state hs;
int retval;
unsigned char IV[16];
unsigned char IV2[16];
unsigned char key[32];
aes_context enc_ctx;
aes_context dec_ctx;
havege_init(&hs);
havege_random(&hs, IV, 16);
havege_random(&hs, key, 32);
strncpy(IV, IV2, 16); //copy IV
aes_setkey_enc(&enc_ctx, key, 256);
aes_setkey_dec(&dec_ctx, key, 256);
//encrypt
aes_crypt_cbc(&enc_ctx, AES_ENCRYPT, 64, IV, buff[0], buff[1]);
printf("Before encrypt:%s\n", buff[0]);
//decrypt
aes_crypt_cbc(&dec_ctx, AES_DECRYPT, 64, IV2, buff[1],buff[0]);
printf("After decrypt:%s\n", buff[0]);
return 0;
}
I am getting the error
In function `main':

Next to the header files, you will also need the .c files! (aes.c, havege.c) and compile those in your code.
On the implementation side:
* Are you sure you want to use HAVEGE? There are lots of doubts on its effectiveness (depending on the system you run on), the standardized CTR-DRBG seems to be a much better choice..
I think your error has something to do with linking to the Aes and Havege files. Your compiler is not recognizing them!
Are they in the same folder as your main? If they are in the same folder, then remove the "polarssl/" from the headerfile name at the top.
Or maybe, when compiling be sure to include aes.c and aes.h too. I found that I was getting the same error due to this. I was only including aes.h in compiling.
Example
$terminal: gcc main.c aes.h aes.c -o encrypt
Just wondering?
If you want to use only aes, why are you trying to use havege.h?
I created a new 'C++ library' project in Qt, which has the following header file:
#include "Test_global.h"
#include <QString>
#include <QTcpServer>
class TESTSHARED_EXPORT Test : QTcpServer
{
Q_OJECT
public:
Test();
~Test();
signals:
void NewMessage(QString);
};
(The implementation file is basically empty.)
When I try to build the object, I get errors:
Test.h:8: error: ISO C++ forbids declaration of ‘Q_OJECT’ with no type
Test.h:10: error: expected ‘;’ before ‘public’
Test.cpp:3: error: definition of implicitly-declared 'Test::Test()'
So it looks like moc isn't processing the file at all. What have I done wrong?
It should be Q_OBJECT, not Q_OJECT.
Greetings all,
I am trying to implement a QT Plugin with CMake. But this "Q_EXPORT_PLUGIN2" directive stops my class from compiling. I can compile the plugin if I commented this out,but it won't work as a plugin if I do so.
QT doc says:
Q_EXPORT_PLUGIN2 ( PluginName, ClassName )
The value of PluginName should
correspond to the TARGET specified in
the plugin's project file
What about in CMake case? What should be the value for 'PluginName'?
Here is my Plugin Interface :
#ifndef RZPLUGIN3DVIEWERFACTORY_H_
#define RZPLUGIN3DVIEWERFACTORY_H_
#include <QObject>
#include "plugin/IRzPluginFactory.h"
class RzPlugin3DViewerFactory :public QObject,public IRzPluginFactory{
Q_OBJECT
Q_INTERFACES(IRzPluginFactory)
private:
QString uid;
public:
RzPlugin3DViewerFactory();
virtual ~RzPlugin3DViewerFactory();
IRzPlugin* createPluginInstance();
IRzPluginContext* createPluginContextInstance();
QString & getPluginUID();
};
#endif /* RZPLUGIN3DVIEWERFACTORY_H_ */
And implementation
#include "RzPlugin3DViewerFactory.h"
#include "RzPlugin3DViewer.h"
RzPlugin3DViewerFactory::RzPlugin3DViewerFactory() {
uid.append("RzPlugin3DView");
}
RzPlugin3DViewerFactory::~RzPlugin3DViewerFactory() {
// TODO Auto-generated destructor stub
}
IRzPlugin* RzPlugin3DViewerFactory::createPluginInstance(){
RzPlugin3DViewer *p=new RzPlugin3DViewer;
return p;
}
IRzPluginContext* RzPlugin3DViewerFactory::createPluginContextInstance()
{
return NULL;
}
QString & RzPlugin3DViewerFactory::getPluginUID()
{
return uid;
}
Q_EXPORT_PLUGIN2(pnp_extrafilters, RzPlugin3DViewerFactory)
Error Message is :

Ok , I fixed the problem by giving the project name specified in Cmake file.
PROJECT (RinzoDLPlugin3DViewer CXX C)
So,now in CPP file its
Q_EXPORT_PLUGIN2(RinzoDLPlugin3DViewer , RzPlugin3DViewerFactory)
and included qpluginh.h
#include <qplugin.h>
I think the macro should be Q_EXPORT_PLUGIN2(pnp_rzplugin3dviewerfactory, RzPlugin3DViewerFactory) or whatever you have listed as the target name in the .pro file. In fact, the "pnp" part stands for "Plug & Paint" which is the Qt demo program for writing plugins :)
Edit:
Since I misunderstood how CMake works, this information isn't really relevant to the OP. I did do a quick search however and turned up this discussion of Qt, plugins and CMake. I hope there is some useful info there.
