38. To do all this YOU must become
INDUSTRY READY ENGINEER

39. HOW TO START A PROJECT

40. HOW TO INVENT AN INVENTION

41. PROJECT PROCESS
1. GOOGLE
2. LITERATURE SURVEY
3. BASE PAPERS
4. BLOCK DIAGRAM
5. PAPER READY CIRCUIT DESIGN
6. SIMULATION
7. HARDWARE IMPLEMENTATION

43. ALMOST ALL REAL TIME PROJECTS ARE
EMBEDDED PROJECTS
• PROCESSOR OR CONTROLLER
• SPECIFICATIONS - no. of input pins , no. of
output pins, no. of serial communication
• SENSOR UNITS / PERIPHERALS
• PROGRAMMING
• SERIAL COMMUNICATION
• SOFTWARE BACKEND

44. CHOOSING PROCESSORS
• 8085
• 8086
• 8051
• ATMEL
• PIC
• AVR
• ARM
• MSP430

45. CHOOSING SENSORS
TEMPERATURE – PRESSURE – ACCELEROMETER – IR SENSORS
CHOOSING THEM ACCORDING TO YOUR PROCESSOR
COST EFFECTIVE
SPEED / RANGE / RELAIABLITY /WEIGHT

47. TYPICAL PROJECT BATCH
• ONE DOES ALL THE WORK
• ONE JUST DOES THE TYPING WORK
• ONE DOESN’T EVEN KNOWS WHATS
HAPPENING IN THE PROJECT
• THE LAST ONE DISSAPPEARS AND COMES
ONLY ON THE DAY OF SUBMISSION

48. SIMPLE BLOCK
PERIPHERALS MICROCONTROLLER SENSORS

• RXD
• ….

57. Send me an ‘A’
#include "reg_51.h"
char uart_data;
void main (void)
{
SCON = 0x50; /* uart in mode 1 (8 bit),
REN=1 */
TMOD = TMOD | 0x20 ; /* Timer 1 in mode 2 */
TH1 = 0xFD; /* 9600 Bds at 11.059MHz */
TL1 = 0xFD; /* 9600 Bds at 11.059MHz */
ES = 1; /* Enable serial
interrupt */
EA = 1; /* Enable global interrupt
*/
TR1 = 1; /* Timer 1 run */
while(1); /* endless */
}

58. void serial_IT(void) interrupt 4
{
if (RI == 1)
{ /* if reception occur */
RI = 0; /* clear reception flag for
next reception */
uart_data = SBUF; /* Read receive data */
SBUF = uart_data; /* Send back same data on
uart*/
}
else TI = 0; /* if emission occur */
/* clear emission flag for next emission*/
}

59. INTERRUPTS

60. EMBD-C PROGRAM
Example: Timer1 interrupt (when TF1 is set)
Example: Ext0 interrupt ( when signal is given to ext0 pin)
