This is my Arduini program I want to Convert to Matlab program anyone help?

[Walter Roberson]

Are you asking how to convert it into MATLAB calls to writeDigitalPin() and so on, so that MATLAB would be in control and telling the Arduino what to do at each step?

Or are you wanting to write a program that does something similar, but using the Data Acquisition Toolbox to talk to some data acquisition card and to control motors, without involving any Arduino, such as for the case where even a higher end Arduino is too slow for your purposes?

Or are you asking how to modify this program so that MATLAB can start it up on an Arduino ?

[Image Analyst]

What sort of help do you need? There is Arduino help on the web site: https://www.mathworks.com/videos/arduino-and-matlab-reading-inputs-and-writing-outputs-106502.html?type=shadow

As far as converting your code, someone just has to go through it line by line converting to MATLAB syntax, and that might as well be you, right?

Answer 2

[Madhu Govindarajan]

Is this the resource you are looking for?

https://www.mathworks.com/help/supportpkg/arduinoio/ug/add-lcd-library.html

If you create an add-on using this workflow, then there should be an equivalent to most of the Arduino functions from MATLAB and you can control the LCD.

If not, please post information about the actual sensor itself for others here to help.
