8. Definition
It is a combination of software and
hardware designed to perform specific
task
It is a system which is hidden inside
Everything other than PC is an embedded
system
It works under certain time constraint
9. Characteristics
Works in a time constraint environment
Good performance and high reliability
Less cost requirement due to mass
production
Designed for specific task
10. Why embedded systems????
Very rapid growing field
Various effect on our daily lives
We use them everyday
22. I2C
A0-A2 => Address inputs A0 VCC
SDA => Serial Data WP
A1
SCL => Serial Clock Input I2C
A2 SCL
WP => Write Protect
GND SDA
23. Features
• WP Pin for Hardware Data Protection
• Low Voltage and Standard Voltage
Operation
• 2-Wire Serial Interface
• 8-Byte Page (2K), 16-Byte Page (4K,
8K) Write Modes
• High Reliability
– Endurance: 1 Million Cycles
– Data Retention: 100 Years
31. Code For Com. Address
#include <stdio.h>
#include <dos.h>
void main(void)
{
unsigned int far *ptraddr; /* Pointer to location of Port Addresses */
unsigned int address; /* Address of Port */
int a;
ptraddr=(unsigned int far *)0x00000400;
for (a = 0; a < 4; a++)
{
address = *ptraddr;
if (address == 0)
printf("No port found for COM%d n",a+1);
else
printf("Address assigned to COM%d is %Xhn",a+1,address);
*ptraddr++;
}
}
32. Things I Learnt here
Programming of microprocessor and
microcontrollers
How to start designing a circuit
How to remove the bugs
How to interact with others
To have patience while working
