I am trying to make a GUI and I need my arduino to be I2C interfaced. I have used the arduinoIO package before but not with the I2C interface. After going through the Mathworks documentation, I found this tutorial Can anyone tell me where I can find the complete documentation for the I2C library? I already checked the arduinoIO.m file and 'Libraries' doesn't even seem to be an input. Does MATLAB(R2014a) have an inbuilt ArduinoIO package? I have been using one from MATLAB File Exchange.
Thanks in advance
You can see this a link 1 but if you aren't sure what is I2C you can read this tutorial I2C
If you are using R2104a or higher, you need to be using the Arduino support package from the main MathWorks web page, not the one from the File Exchange. Whether or not that includes I2C support, I don't know.

I am wondering, is it possible to add CMSIS and HAL libraries at the same project in KEIL...
based on my knowledge I added CMSIS libraries in different folder but in compiling I got these errors...
Do you guys have faced with this problem?
Can you help me?
note: the main project was written in CMSIS and I don't want to rewrite it in Hal.
There are 2 files:1-stm32f4xx_hal.h,2-stm32f4xx.h
The first one is defined and used in HAL and the second one is for CMSIS, how can I use both of them in one project?
THIS IS THE ERROR:" #error "Please select first the target STM32F4xx device used in your application (in stm32f4xx.h file)" "
and in below is the screenshot.
THANKS.
The STM32 HAL always depends on CMSIS. You cannot use the HAL library without CMSIS.
The error message you have received clearly explains what you have done wrong and what you need to do to fix it. I cannot explain it any more clearly than that.
#error Please select first the target STM32F4xx device used in your application
You might also appreciate to read the comment immediately before the line you have highlighted:
/* Tip: To avoid modifying this file each time you need to switch between these
devices, you can define the device in your toolchain compiler preprocessor.

I want to know is it possible to run pyqt5 on micropython(pyboard),I think micropython library is too small.
pyQT is not an option here. Read following discussion here to find and choose suitable GUI lib for your micropython project.
From my personal experience- my choice was LVGL library for small ILI9341 touch screen.
Hi Im quite new in Arduino and electronics so bear with me.
I have a project to control a step motor using Matlab and Simulink. For now I just want to get the thing up and running. I have hooked up the schematic tested it with a simple code for a step motor and it works (this has been done without Matlab). My problem is how can i get the motor to run using Simulink and Matlab?
When i try to Run the Simulink model i get this
My step motor driver board is ULN2003APG and my motor is
.
I have downloaded the Arduino Hardware Support Package for Matlab and have already uploaded the server program to Arduino to enable communication between Matlab and Arduino.
I have no idea what might be causing the error that i get. Any help would be greatly appreciated!
If there are any existing guides or any examples covering such topics u can redirect me to them.
(If there is a need to write a new driver for the board please send me some tutorial where I can read about that.)
Thanks in advance.
EDIT!
Here are step by step the things that I do to try and get my Simulink model to run:
1: Complete the steps in this tutorial.
2: Download MATLAB Support Package for Arduino.
3: Connect the arduino uno to PC, open the Arduino IDE and upload adioes.pde from step 2.
4: Open Matlab change working path (if not it gives an error)
5: Open existing example from downloaded MATLAB Support Package for Arduino ...\ArduinoIO\examples\stepper_sim.mdl
6: Change COMPORT and click Tools/Run on Target Hardware/Prepare to run and after that Tools/Run on Target Hardware/Run
After that I get my error.
Here is a nother image of the simulink model:
From your file name it looks like you have downloaded this from a file exchange submission "MATLAB Support Package for Arduino (aka ArduinoIO Package)". Based on one of the comments in that submission this package does not support code generation. It can be run only using Simulink "normal" mode. For other targets which require code generation you need tlc files and you will see this error.
I believe the error window already tells you what is the problem. You need to move the file msfun_arduino_io_setup.tlc to you project's working directory. We can only have this much sight in your project with what you have given to us. If there is, you need to give more information, for instance SS of your Simulink Model.
Besides all, I suggest you to download Arduino Support Package and other add-ins, extensions and files from Matlab itself if you can.
I've finaly managed to get the stepper motor running using Simulink. Unfortunately I had to change the driver board to do that. It seems there isn't a driver from Matlab for this board or it's just not compatible (not sure).
I've bought an adafruit motor shield v2 and things worked perfectly. It no longer give's that error about a missing .tlc file.
Cheers !
First off I'm not a regular Matlab user, so this might appear as a rather simple question, but how do you install Apps in Matlab R2012a? Is it even possible? I found a link for how to do it in R2012b here, but I can't find any guidelines on how to do it in R2012a.
I have a custom app that was sent to me by a colleague at another research institution, and I think they must have a more recent version of Matlab that us. His instructions were to go to the Apps tab in the tool bar and select Install Apps, but in R2012a, I can only see File, Edit, Debug, Parrallel, Desktop, Window and Help. I've also had a look in the Product Help guide in Matlab, but I couldn't find a relevant entry.
Any help would be greatly appreciated.
I believe MATLAB apps were introduced in R2012b, and that it's not possible to install or use them in earlier releases. You would need to contact your colleague, and ask them to supply an unpackaged version of the application (i.e. just the code).
I am currently working on a small project in QuickBasic that requires the use of MIDI files.
As the DOS environment I'm using DOSBox 0.74, which provides emulation of the Gravis Ultrasound card.
So far, I've been able to access GUS only by using the PLAYMIDI.EXE file in the C:\ULTRASND directory. However, it is impossible to launch it from inside QuickBasic: the SHELL statement creates a child COMMAND.COM process, so when PLAYMIDI.EXE starts playing in the background the child process finishes and terminates, and the music stops. All of this means that the only way to launch PLAYMIDI.EXE is through a batch file before the actual program, but it also means that there is no way to control the music from the QuickBasic program. Edit (Jul 24, 2011): It is actually possible to launch it using SHELL (my mistake), but the TSR version of PLAYMIDI.EXE takes a lot of memory, so there isn't enough left for my program. The question still stands.
Therefore, my question is whether there is a Gravis Ultrasound library for QuickBasic available.
Edit (Jul 19, 2011): Might be in another language as well, as QuickBasic can link those too.
P.S. Sound Blaster library available here, but I don't like the sound it produces.

As an huge fan of QB, I'm happy to see someone still using it. So I made it a point to find an answer for you. Here's what I've found. There is an ASM Gravis library on this page. Using the ASM tutorials, you should be able to combine the two. FYI, here's another great resource. Good luck.
You could look at DS4QB++, which allows you to play music and sound effects using the Windows API. I haven't tried it with later versions of Windows though. There's also BWSB which is DOS based and can play MOD/S3M files. Both available on my old QB site:

QB64 uses TiMidity, i guess via _SNDOPEN.
