driver code for raspberry pi led in matlab

First, you need to make sure that the MATLAB Support Package for Raspberry Pi Hardware is installed. You can follow the instructions to install it from the MATLAB Add-Ons toolbar or from the MATLAB command line interface.

Once it's installed, you can create a connection object to your Raspberry Pi using the command mypi = raspi(). Next, connect your LED to pin 18 on the Raspberry Pi. Make sure you have the appropriate resistor in line with the LED.

To turn the LED on, use the following command:

main.m
writeDigitalPin(mypi, 18, 1);
30 chars
2 lines

To turn the LED off, use the following command:

main.m
writeDigitalPin(mypi, 18, 0);
30 chars
2 lines

Make sure you replace "18" in the above command with the actual physical pin number to which the LED is connected.

Here's an example code snippet which alternately turns on and off the LED:

main.m
mypi = raspi();
pin = 18;
for i = 1:10
    writeDigitalPin(mypi, pin, 1);
    pause(1);
    writeDigitalPin(mypi, pin, 0);
    pause(1);
end
