IO ports on the rabbit

To program the IO ports A and B for simple read and write operations, you can use a microcontroller such as the Arduino Uno. First, you’ll need to declare the pins corresponding to ports A and B as inputs or outputs using the pinMode() function. For example, to set port A as output and port B as input:
cpp
Copy code

// Set port A as output
pinMode(PORTA_PIN, OUTPUT);

// Set port B as input
pinMode(PORTB_PIN, INPUT);

Then, you can write data to port A using the digitalWrite() function and read data from port B using the digitalRead() function. For instance, to write a HIGH value to port A and read from port B:
cpp
Copy code

// Write HIGH to port A
digitalWrite(PORTA_PIN, HIGH);
// Read from port B
int data = digitalRead(PORTB_PIN);

Make sure to replace PORTA_PIN and PORTB_PIN with the actual pin numbers corresponding to ports A and B on your microcontroller. his example demonstrates premium quality essays read and write operations on IO ports A and B using Arduino syntax.
