NOW A DAY’S STUDENTS ARE NOT MUCH INTERESTED TO GO TO
COLLEGES. TO LOOK AFTER SUCH PERSONS OUR EMBEDDED PROJECT IS VERY
MUCH USEFUL. AT ACCORDING TO THIS PROJECT WE WILL ISSUE AN I-BUTTON
TO EACH AND EVERY STUDENT IN THE COLLEGE. IN OUR PREMISES WE WILL
KEEP A READER FOR THAT I-BUTTON. THAT READER I ATTACHED WITH A
MICROCONTROLLER BASED BOARD ALONG WITH GSM MODEM. WHILE STUDENT
ENTERS INTO COLLEGE HE HAS TO KEEP HIS I-BUTTON AT THE READER. BY
KEEPING HIS I-BUTTON AT THE READER AN INTERRUPT WILL BE GENERATED
AND USING THAT INTERRUPT A MESSAGE WILL BE SENT TO HIS/HER PARENT
AUTOMATICALLY.
THE SYSTEM USES A COMPACT CIRCUITRY BUILT AROUND FLASH
VERSION OF AT89S52 MICROCONTROLLER. PROGRAMS ARE DEVELOPED IN
EMBEDDED C. ISP IS USED TO DUMP THE CODE INTO THE MICROCONTROLLER.
SOFTWARE:
EMBEDDED ‘C’
RIDE TO WRITE CODE
ISP TO BURN THE CHIP
HARDWARE:
