Hi, I want only one simulink browser, control two arduino mega2560
but arduino mega only 3 interrupt pin so I want using 4 interrupt pin than I must using 2 ardubio mega2560
problem is one simulink brower only using one arduino so I can't using 4 interrupt pin.
someone solve this problem, please remain me...

Connecting two arduinos to Simulink is not easy. Could you explain what you are trying to achieve?
FYI, Arduino Mega 2560 has 6 interrupt pins: 2,3,18,19,20,21

I want 4 DC motor control so one DC motor using A and B encoder.
1 DC motor encoder using 2 interrupt pins
num 0 motor 2,3 interrupt pins
num 1 motor 18, 19 interrupt pins
num 2 motor 20, 21 interrupt pins
num 3 motor ??, ?? interrupt pins
so I using two arduino mega2560, finally I must using interrupt pins
can u give some Tip connect two mgea 2560?.

You could use one Arduino as Master and the second a slave.
Computer -> (usb cable) -> Arduino1 -> (digital or analog pins) -> Arduino2
Motor 1 & 2 Motor 3 & 4
If Arduino is not critical to your design, you can use an ESP32. This board is dual core and has up to 32 interupts per core. You can program it using Arduino IDE.
