MATLAB: How to tell serial ports apart

MATLABserial port

I have these two ports on my computer

How do I tell them apart? One is Serial Device and the other one is Serial Port

I tried serialportlist but that only gives me the serial ports names. How do I decide which is which base on their properties?

Currently serialportlist function does not provide any additional details about the connected serial devices. I have conveyed this issue to the concerned people and it might be considered in the future releases.

Do not continually close and open the serial port.

The default for serial ports is to read asynchronously. You have to change the serial port properties to read synchronously.

You have not changed your serial port terminator character, as is needed for arduino. See the MATLAB File Exchange contribution that shows a GUI for interacting with arduino devices.

MATLAB: How to configure a GPIO pin as an external interrupt in a Target Support Package

The attached model configures GPIO0 as external interrupt to trigger the blinking of LED. The custom code in the System Initialize block assigns GPIO0 as an input to trigger the XINT1 interrupt:

EALLOW;                                        
GpioCtrlRegs.GPAMUX1.bit.GPIO0 = 0;            
GpioIntRegs.GPIOXINT1SEL.bit.GPIOSEL = 0;      
EDIS;                                          
XIntruptRegs.XINT1CR.bit.ENABLE = 1;           
XIntruptRegs.XINT1CR.bit.POLARITY = 1;

The ISR toggles the LED based on a rising edge of GPIO00. Connect GPIO to 3V and GND in order to blink the LED.
