Fab Academy 2019 CIT-FABLAB

Group assignment

For this assignment, we tested the development of an interface that none of the 3 has used, one created by MATLAB

Board

Atmega328p

Because it is necessary to use aruino libraries to achieve data communication between the board and matlab, we decided to use a plate with atmega 328p as a microcontroller, in this case we use Italo's, you can see his repository for see the design and fabrication process

Arduino programming

As Italo has already burned bootloader, we can load the library that will allow access to matlab and transmit the data, you can download the code below

It is very important once the code is loaded to keep the FTDI connected, since the communication will be through this serial port

MATLAB GUI

Once these steps are done, we open matlab, once there with the GUIDE command we select to create a new GUI

In this extension .fig we will place the elements of the interzad, I will place 3 buttons and some texts that recognize the state of the variables that I will use

And I will also add a small logo

so you would see the interface

Then we proceeded to program the .m extension with the matlab language, this is where we define the functions of the elements of interest, in our case we place 3 buttons which will send text type data to the arduino and make the loop to turn the led physically, for that reason here we must define the outputs of the board as well as the port to which it is connected,
