# ATmega32 

here we have 4 ports (A,B,C,D) and each port has 8 pins

![img](https://github.com/SamanKhalife/AVR-Microcontroller/blob/main/images/ATmega32.png)

# Some Basics

DDRx = setting port type

input = 0

output= 1

### Assume the port A is an input port

```

DDRA = 0x00                 AAAA,AAAA

       __                   0000,0000

       |                     0  ,  0 

this tow digit shows Hexadecimal initialization

```

### Assume the port B is an input port

```

DDRA = 0x00                 BBBB,BBBB

                            1111,1111

                             1  ,  1 

```

### If pins 2, 4, and 7 are input pins and pins 1, 5, and 6 are output pins

```

AAAA,AAAA

0110,x01x

```

toggle ----> Pins that are not connected to anything (we can set 0 or 1)

### Port initialization

`PORTx`   like  `portA=0x54` 

### Pin initialization

`Pinx.n = y`  like   `pinA.2 = 1`
