7. Address, Data and Control Bus
• Bus - defined pathway for transfer of digital information
between different units.
• To write data to memory or output device.
- µp needs to send
. Address of memory location or port
address of device.
. Data
. Write control signal
• To read data from memory or Input device
- µp needs to send
. Address and
. Read Control Signal
- Memory/device sends – data.
8. Thus three pathways (buses) for 3 types of digital
information.
Address Bus - From µp to devices
- Unidirectional.
Data Bus - From µp to devices & devices to µp
- Bidirectional
Control - From µp to devices & from devices to µp
[Interrupt, DMA]
- Bidirectional
Now let us redraw the computer organization diagram

a CPU, memory, a clock oscillator, and I/O on a single
integrated circuit chip. [1]

14. • The 8051 was one of the very early microcontrollers
(~1980).
• One of the early Arduino-like project was based on
the 8051, in the form of "8052 Basic" board.
• Atmel, Mentor Graphics, Intel, Honeywell, and Maxim
(Dallas Semiconductor), and may more have a variety
of 8051 chips.
15. • Introduced in 2005 as a project for students at the Interaction Design
Institute Ivrea in Ivrea, Italy, Arduino is a single board microcontroller.
• An Arduino board consists of an Atmel 8-bit AVR microcontroller with
complementary components to facilitate programming and incorporation
into other circuits [2].
• Arduino can sense the environment by receiving input from a variety of
sensors and can affect its surroundings by controlling lights, motors, and
other actuators.
• The boards can be assembled or purchased preassembled; the open-source
IDE can be downloaded for free.
• The Arduino programming language is very simple and follows C like
syntax.
• Arduino projects can be stand-alone or they can communicate with
software running on a computer (e.g. Processing).
16. • Other similar microcontrollers platforms are:
Parallax Basic Stamp, Netmedia's BX-24,
Phidgets, MIT's Handyboard, and many more.
• All these platforms have an easy-to-use
package.
Why Arduino?
Arduino also simplifies the process of working with
microcontrollers, but it offers some advantage:
17. 1. Inexpensive - Arduino boards are relatively inexpensive
compared to other microcontroller platforms.
2. Cross-platform - The Arduino software runs on Windows,
Macintosh OSX, and Linux operating systems. Most
microcontroller systems are limited to Windows.
3. Simple, clear programming environment - The Arduino
programming environment is easy-to-use.
4. Open source and extensible software- The Arduino software
is published as open source tools. The language can be
expanded through C++ libraries.
5. Open source and extensible hardware -The Arduino is based
on Atmel's ATMEGA8 and ATMEGA168 microcontrollers.

30. Microcontroller Ports and Pins
The communication channels
through which information flows
into or out of the
microcontroller
Ex. PORTB
Pins PB0 – PB7
May not be contiguous
Often bi-directional
C
See next slides!
31. Port Pin Data Directionality
• Input
– When you want to take information from the external
world (sensors) into the MCU
• Output
– When you want to change the state of something outside
the MCU (turn a motor on or off, etc.)
• Pins default to input direction on power-up or reset.
• Your program can set or change the directionality of
a pin at any time
33. Setting the Pin Data Direction
• Arduino
– pinMode(pin_no., dir)
• Ex. Make Arduino pin 3 (PD3) an output
– pinMode(3, OUTPUT);
– pinMode(PIN_D3, OUTPUT); // with me106.h
– Note: one pin at a time
• Suppose you wanted Arduino pins 3, 5, and 7 (PD3,
PD5, and PD7) to be outputs?
• Is there a way to make them all outputs at the same
time?
34. Pin Used as an Output
• Turn on an LED, which is connected
to pin Arduino pin 0 (PD0)
– What should the data direction
be for pin 0 (PD0)?
• pinMode(____, ____);
– Turn on the LED
• digitalWrite(0,HIGH);
– Turn off the LED
• digitalWrite(0,LOW);
ATmega328
Arduino
pin 0
(PD0)
35. • Recall the question:
– Is there a way change the data direction for a set of pins all
at the same time?
• All the work of MCU happens through registers
(special memory locations)
– Registers on the Atmega328 are 8-bits wide
• The data direction register (DDRx) handles the data
directions for pins in PORTx
Source:http://www.atmel.com/dyn/products/product_card.asp?PN=ATmega328P p. 93
Pin Used as an Output
36. Data Direction Register
• If the bit is zero -> pin will be an input
– Making a bit to be zero == ‘clearing the bit’
• If the bit is one -> pin will be an output
– Making a bit to be one == ‘setting the bit’
• To change the data direction for a set of pins
belonging to PORTx at the same time:
1. Determine which bits need to be set and cleared in DDRx
2. Store the binary number or its equivalent (in an alternate
base, such as hex) into DDRx
37. Example 1
• Arduino approach • Alternate approach
Make Arduino pins 3, 5, and 7 (PD3, PD5, and
PD7) to be outputs
pinMode(3, OUTPUT);
pinMode(5, OUTPUT);
pinMode(7, OUTPUT);
DDRD = 0b10101000;
or
DDRD = 0xA8;
Or if me106.h is used:
pinMode(PIN_D3, OUTPUT);
pinMode(PIN_D5, OUTPUT);
pinMode(PIN_D7, OUTPUT);
38. Example 2
• Arduino approach • Alternate approach
Make pins Arduino pins 0 and 1 (PD0 and PD1)
inputs, and turn on the LEDs connected to it.
pinMode(0, INPUT);
pinMode(1, INPUT);
digitalWrite(0, HIGH);
digitalWrite(1, HIGH);
DDRD = 0; // all PORTD pins inputs
PORTD = 0b00000011;
or
PORTD = 0x03;
Or if me106.h is used:
pinMode(PIN_D0, INPUT);
pinMode(PIN_D1, INPUT);
digitalWrite(PIN_D0, HIGH);
digitalWrite(PIN_D1, HIGH);

44. • The Arduino Duemilanove can be programmed with the
Arduino software.
• The Arduino integrated development environment (IDE) is
written in Java, and is derived from the IDE for the
Processing programming language.
• It includes a code editor with features such as syntax
highlighting, brace matching, and automatic indentation,
and is also capable of compiling and uploading programs
to the board with a single click. A program or code written
for Arduino is called a "sketch".[3]
• Arduino programs are written in C or C++.

• An arduino program == ‘sketch’
– Must have:

– setup()
• configures pin modes and
registers
– loop()
• runs the main body of the
program forever
– like while(1) {…}
– Where is main() ?

DELAY_OFF msec, and repeats

// initialize the digital pin as an output:
pinMode(LED_PIN, OUTPUT);
}

// as long as the Arduino has power
void loop()
{
digitalWrite(LED_PIN, HIGH); // set the LED on
delay(DELAY_ON); // wait for DELAY_ON msec
