Interfaces - Hardware & Software communication

This repository store the related information to the course INTERFACES in the Universidad del Valle, this course is focus on develop a software application that interact with the hardware itself.

Designe by: Kevin Jofroit Joven Noriega.

This application was designed using Java in a Eclipse enviorement. The programming of the hardware was using the Arduino MEGA.

The requeriments of the project are the following:

• Analog input 4 channels.
• Digital input 4 channels.
• Digital output 4 channels.
• Change of the sample frequency.
• Change of the windows size.
• Send the information in a continuous way.
• Plot the realted information about the selected channel.
• Storage all the information in the process.

The following image show the graphics interface that is compose by diferent buttons, that are explain like follow:

• PORT: Show the currently channels available where is connect some device.
• SET: Define the channel to send/recive the information.
• SAMPLE TIME: Stablish a sample time to the analog signal, this value depends of the velocity of the device.
• WINDOW: The size of the samples to plot in the interface.
• INPUT TYPE: Define the input type signal.
• ANALOG INPUT: Define the analog channel.
• DIGITAL INPUT: Define the digital channel.
• DIGITAL OUTPUTS: Turn on/off the output channels.
• RECOMMENDATION BOX: Show relevant information about error in the exacution or configuration of the device. e.g. String in the SAMPLE TIME.
• PLOT: Plot the information related with the channel.
• STOP: The the plot of information.
• SAVE: Save the data in the desktop with a predefined title.
• SAVE: Save the data in a ADDRESS specific and TITLE define.

COM4 are stablish to do the communication.

Plotting information related to the Analog channel 2, with a sample time of 0.1 [s] and window size 50. The output channel related with RED & BLUE are turn on.

Plotting information related to the Analog channel 3, with a sample time of 0.1 [s] and window size 50. The output channel related with RED & BLUE are turn on.

Plotting information related to the Digital channel 2, with a sample time of 0.1 [s] and window size 100. The output channel related with RED & BLUE are turn on.
