A tutorial for how to read a serial port in a TI C2000 Dev. Kit with simulink.

Hi everyone, I am suffering to find any kind of tutorial on how to read in real time some input from my board using Simulink. I have a C2000 F28379D LaunchPad and I want to use one of the inputs to read an analog signal (like a potentiometer) and to show in real time in one program in Simulink, but I can not find anything.

I know this sounds very basic, but I did not find anything about it, if anyone can inform me.

Hi,

You can download the model file that I've attached.

ADC sampling at 10KHz,

1KHz signal to sample and hold.

Pin 30 (J3-30) for analog input

Pin 70 (J7-70) for DAC out

GPIO out is a blinking led on launchpad to observe if the program is running.

Last but not least

Right Click on "My Computer" > Properties > Device Manager > Ports

Check if XDS100 Class USB Serial Port (COM4)

else note which COMX it is connected (COM3,COM4,....)

if its COM4 it is okay

if not

Return to your simulink window, click on gear symbol (Properties)

Select Hardware Implementation

Click Target Hardware Resources

Scroll all the way down

There is "External mode" section (All after GPIO AND DMA...)

Scroll all the way up

Communication interface : Serial

Serial Port : COM4

Change it to (COM3,5,10.... whatever your port is)
