UART Communication Protocol Details

UART (Universal Asynchronous Receiver/Transmitter) mode operates as follows:

  1. Idle State: A non-return-to-zero (NRZ) state where the serial line maintains a logic state of 1.
  2. Start Bit: A signaling flag indicating the beginning of a byte, marked by a 1-to-0 transition. The receiver detects this transition at the middle of the bit interval (T).
  3. Data Bits: Following the start bit, typically 8 data bits are transmitted on the TxD line and received on the RxD line over

C++ Pointers and Structs: Code Examples

Pointer Basics

int x;

int y;

int *p = &x;

int *q = &y;

x = 35; y = 46;

p = q;

*p = 78;

cout << x << endl;

cout << y << endl;


int *p;

int *q;

p = new int;

q = p;

*p = 46;

*q = 39;

cout << *p << endl;


int *p;

int *q;

p = new int;

*p = 43;

q = p;

*q = 52;

p = new int;

*p = 78;

q = new int;

*q = *p;

cout << *p << endl;
