I'm using Ubuntu 14.04 (64 bit). After installing leJOS_NXJ_0.9.1beta-3, I was able to flash the NXT device. However, when I tried to upload a program, it showed a message "Found NXT: NXT 0016530CDF15" and then just stuck there.
I also tried Eclipse with leJOS plugin, and got the same problem. It showed
Program has been linked successfully
Uploading ...
Found NXT: NXT 0016530CDF15
and it got stucked there.
Can anybody help me with this issue?
Thanks,
Thuy
This site might be able to help, it provides the information to install and configure correctly all the software necessary for you to develop Java programs for the NXT, maybe by following this site it will hopefully fix the problem.
This tutorial will show you how to install and configure all the software necessary for you to develop Java programs for the LEGO Mindstorms NXT. Java is much more powerful and flexible than the original NXT-G software that LEGO provides. We will be using the Eclipse editor to write the actual Java code and to download this into the NXT. This combination enables you to conveniently write software and to quickly test it on the NXT. Of course there are many other Java editors, but we consider this combination to be particularly convenient. This tutorial focuses on the Windows XP platform, A Mac OS X tutorial is also available. We have two additional steps for Windows Vista. You will work through the following five steps - See more at: http://www.bartneck.de/2008/03/04/java-lego-nxt-eclipse-tutorial/#sthash.h1ZOZvlX.dpuf

I have bought, downloaded and then installed uFlex for Unity. The install seemed to go without any errors, but when I try to run any of the example scenes I get lots of errors. The first and most serious sounding of which is:
DllNotFoundException: flexRelease_x64
uFlex.FlexSolver.Start () (at Assets/uFlex/Scripts/Solver/FlexSolver.cs:102)
Also the scenes don't seem to run/work. Have tried googling to see if it's a common error but that didn't show up anything. Tried finding the missing DLL but not sure where to put it, or whether it's platform/version specific?
Any thoughts on how to troubleshoot this
Anyone else have similar issues?
Not sure if it's relevant but I'm running Unity Version 2017.2.ob11 Personal, and my OS is Ubuntu 16.04.5 LTS. I have windows installed as well - is switching to running Unity under Windows likely to help?
It won't and shouldn't work on Linux at this point.
Read the requirement from the plugin page:
NVidia GPU with at least CUDA 3.0 compute capability
Windows 64 bit (Win 32bit experimental, Android and Linux support planned)
The support is currently for Windows. You get the exception because the dll for Linux has not been provided. It can't load Windows dll on Linux. If the native side (C++) of the plugin is open-source, you can compile it for Linux and include it in your project then it should work. Since it's not, your only option at this moment is to switch to Windows.
I am thinking of installing Eclipse for developing STM32 programs (I have a question about this that I will post later). In the instructions it says I have to install:
the IDE for C/C++
GNU ARM Eclipse Plug-ins
GNU GCC ARM tool-chain
among other tools..
However, I am also thinking of installing e2studio for developing Renesas programs. You can see about this Here. There you can see that this is "based on Eclipse CDT" (what is the difference between this CDT and the IDE?) and that it also uses Plug-ins like GNU Tool & Support Here.
My question is, is this possible? Do I have to install them separately? (I guess so). Will the GNU tools will also be installed twice??
(I am using a windows10 machine)
Thanks in advance
CDT is dedicated to C/C++ programming. Actually I personally prefere to have separate eclipse installations for different families of uC. Why? Because it is much easier to manage updates and to keep my work in the correct order.
For STM32 I advice (I think, you are a novice user of Eclipse & ARM toolchains) to install OpenSTM32 (yo have a straightforward installer). It imports projects from CUBEFX & MX which gives you an easy way to import examples & initialisation code from Cube. I personally do not use HAL libraries but as I know I am a minority.
However, I am also thinking of installing e2studio for developing
Renesas programs. You can see about this Here. There you can see that
this is "based on Eclipse CDT" (what is the difference between this
CDT and the IDE?)
Eclipse CDT is an open-source general-purpose C and C++ IDE.
e2studio is one of several software packages that extend CDT with (most likely proprietary) plugins geared towards a more specific market (in this case, Renesas programs).
My question is, is this possible?
Yes.
Do I have to install them separately? (I guess so).
Yes.
Will the GNU tools will also be installed twice?? (I am using a windows10 machine)
You can certainly share a single installation of a toolchain between two installations of CDT, if both of them need the same toolchain (in terms of version and architecture). I don't know enough about STM32 and Renesas to tell you if they use the same toolchain.
So I will start off by saying that I do NOT want know how to setup or run QT on the pi. I am specifically trying to setup Qt Creator 4.0.3 (Based on Qt 5.7.0 (MSVC 2013, 32 bit)) to write and compile C++ and the run it on the Raspberry pi 2. I have found that running qt on the pi is far to slow.
I have searched for two days to find the right toolchain download for qt/raspberry and its corresponding qt configuration. Nothing seems to work. I have found what seems like a thousand dead ends searching the web. I can write and compile apps for windows console fine. But finding information to cross compile for raspberry seems to be an elusive Unicorn!
Does anyone have this working??? If so which of the many toolchains did you use? And please help me replicate your QT configuration. The closest I have come is using the GCC ARM Embedded toolchain but I cant seem to get the QT options set correctly and I believe that only gets me part of the way there. My ultimate goal is to control GPIO and use the RadioHead library.
Thanks in advance!
I also wanted to do that, and I actually achieved it, It's called "cross-compilation", you build on the Main PC and then compile it to the target.
Initially I wanted to use my main PC with windows 10, but I ended creating a linux partition on my pc to do it since I didn't found any way to do it with windows.
Qt has a very comprehensive tutorial with Qt5 and RaspberryPi2 (both with linux), the only problem is you need linux on your pc to do it. If you want to do this I would suggest following this steps:
Create a linux partition with the same os as in the pi (for example raspbian and debian) and name the username (in linux) "pi" and the password "raspberry". This will help you with external libraries.
Install Qt for Linux on your new partition
Follow Qt's tutorial on https://wiki.qt.io/RaspberryPi2EGLFS
The tutorial is really straightforward, I really recommend it.
Good Luck.
I was looking for a debugger for Windows, other than GDB, which is freely accessible. I found WinDbg and it looks quite good so I wanted to give it a try. Now when I go to the MSDN page it offers to download the SDK for Windows 8. As this is a rather big package, I wonder if I can use this WinDbg version still for Windows XP?
Since my company still uses Windows XP for some time to come, I'm stuck with it for now. Is there another, free debugger which is user friendly?
I'm used to Visual Studio for debugging, which is quite nice. Currently I use Eclipse with GCC and GDB. GDB is good enough, but when I do some assembly I don't really like it, and all in all I don't find it very user friendly.
The latest WinDbg will work with Windows 2000 onwards and most commands work with Windows XP. There will be some that will only work with later versions, but these are documented in the included help file.
Just to ease your download pain, firstly there is the option to select what to download from MSDN, or you can just download the version you want here thanks to a kind person who is hosting the individual components.
So I have made GUI frontend for latex with QT5 using QT creator. The application works fine, but I'm unable to deploy it. The deploy option in build is grayed out. I have also tried following this guide but I can't even configure my QT to use static linking. I was able to configure the source, but when I try to run mingw32-make sub-src, it says nothing to do here.
I downloaded QT from here using the link Qt 5.0.1 for Windows 32-bit (MinGW 4.7, 823 MB). I have also downloaded microsoft visual studio express for Windows 8 to get tools required for building c++.
I also tried to install mingw32 manually. I have also installed Strawberry perl, because one guide told me to do that, but that did nothing.
I managed to fix this problem. There was one .dll. Reason why I didn't find it earlier was that my application did not need it by itself, but one of libraries I used was dependaple from it. The missing .dll was icuuc49.dll.
