I wanted to create create 3 UART connections with a Zynq Processor to take data from 3 different receivers. Is there any resources online?

I am working with ADALM Pluto fitted with a Zynq processor and would like to process to transmit and receive data through the SDR. I want to use 3 receivers and gather their data simultaneously. Is there any MATLAB or Simulink resources that might benefit me in any way?

My main goal would be to create 3 different UART connections running at the same time.

Hello Kazi,

To create 3 different UART connections simultaneously you can refer to the following documentation/resource specifically catered towards working with ADALM Pluto via a support package:

https://www.mathworks.com/hardware-support/adalm-pluto-radio.html

Additionally to setup 3 simultaneous UART connections you can use the "serialport" function in MATLAB and Instrument Control Toolbox that provides blocks for Simulink. Here is a example code for your reference on how to use the "serialport" function:

% Create serialport objects for each UART connection
uart1 = serialport("COM1", 9600);
uart2 = serialport("COM2", 9600);
uart3 = serialport("COM3", 9600);

% Write data to UART
write(uart1, data1, "uint8");
write(uart2, data2, "uint8");
write(uart3, data3, "uint8");

% Read data from UART
data1 = read(uart1, numBytes, "uint8");
data2 = read(uart2, numBytes, "uint8");
data3 = read(uart3, numBytes, "uint8");

For further reference on the "serialport" function as well as simulink blocks for UART communication, you can check out the links below:

Hoping these resources are helpful!

If I recall correctly, historically there has been a limit of 2 serial ports in Simulink. I could certainly be wrong about that.
