@ saptarshi mukherjee you can use timer for generation of delay. for 40 khz time=1/40000 so 25 micro second. you can find 8051 timer calculator by googling.
doraemonParticipantYou can interface lcd in proteus to display counter value. for that you have to add code to display counter variable on lcd.
doraemonParticipantHere some useful books. 8051 Microcontrollers: Architecture, Programming, Interfacing and System Design Author : Raj Kamal Pearson Publication
arm system on chip architecture by Steve Furber
doraemonParticipantassembly language program can be written in simple text editor like notepad. Program can be compiled by using command prompt compiler. you should have to download compiler for that. after compilation .hex file is generated that can be burn to controller via hardware called programmer. Comment here if any doubt. I think You Have
doraemonParticipantI suggest you to instead of buying components in bulk first you study some circuits that you can understand and make list of them. then you buy components required in that circuits.
Commonly used transistors are BC547,557.
ICs are 555,4017,4011doraemonParticipantYou can build astable multivibrator using IC555 and at output connect relay to drive bulb. you can find this type of ckt. easily by googling.
doraemonParticipantDownload doc4345 from atmel.com it contains programs to use different timer,counters. If you carefully read it you can surely understand it.
doraemonParticipantHi, RF means Radio Frequency. In this catagory projects that use RFID can be made. you can find abt rfid and some of its projects on this site.
doraemonParticipantAlthough you are interested in embedded system it may be difficult for you as in IT related field there is little or no knowledge of how hardware works. Both Java,Python are high level languages but in embedded you have to deal with assembly language. However it is not difficult if you are interested in it and you can understand about how processor,microcontroller works.
doraemonParticipantYou can use software C51 from keil keil.com this supports both c and asm.many 8051 devices from different manufacturers are also available.
doraemonParticipantAT89S52 IS 8052 controller.
doraemonParticipant8051 is CISC (complex Instruction Set Computer) architecture.
doraemonParticipantHere loop to generate pattern
for(i=0;i<4;i++)
{
for(j=0;j<4;j++)
{
if(i==j)
{
printf(“a”);
}
else
{
printf(“b”);
}
}
printf(“n”);
}doraemonParticipantCheck you have set proper baud rate in 8051 program to communicate with Rx module.
doraemonParticipant$GPGGA,235954.030,0000.0000,N,00000.0000,E,0,00 ( Number of satallite visible) ,,0.0,M,0.0,M,,0000*4C From this it is clear that no of visible satallite is 0. so try to get minimum three satallite to find location go in open space and try if satallite not found you have to use external antenna.
