sir,
i saw a simulator/emulatir type asm code generator.it generates asm code for pic and at89/at90 series asm code. they use that emulator just by clicking by the mouse.
they are using just clicking on the port which are drawn in emulator.in bellow automatically asm code is generated...
why? i need to solve that problem. i am newer in that world. so i faced more problem than others. if you all are interrested to solve my problem then i shall not post anything here.
this is my circuit. i used ne555 and 8051 microcontroller. my moto to add the clock pulse of ne555 to 8051.bkz it helps to addetional clock frequency with 12 Mhz crystal.
that ne555 produce variable clock pulse with the help of 100k priset.so we can controll the blinking rate(off time on time)...
it increase and decrease the blinking rate.
the pulse of 555 is adding in 8051 to increase blinking rate.
i configure that circuit. but i am not able to programming it. so anybody can write the exact code here.

i want to make that project....and i am able to blink leds in constant speed.but that new project i added 555 to controll blinking speed by 100k speed controller.
now how to add that with 8051 by assembly code.plz plz plz help me out
plz send me code here
sir i saw a 8051 based software that generate automatic code for at89 series and 90 series.have to select just timer and delay and type of micro controller.after that have to select the port input and output just clicking by mouse. in generate button by clicking it exactly generate the code or...
sir i fased a problem in my project .
that i took a diagram for my idea to make a improve clock. but i can not understanding the exact pin connection with the display. can anyone explain it from that diagram?
what is dig123456 connected with mc?
what is the abcdefg segment connected with it?
sir i can not understand that diagrma plz help me out and explain the connection.
i can not understand the digit connection with pin numbers of mc along with the segments.
plz tell me the exactly pin connection.
i understand that code.it is cool.
but i need a simple code of asm about that matter.
objective:
1) need to blink a single led continuously
2) drive that led by at89c2051
3) blinking rate controlled by ne555(the preset variable resistance will...
what is the function of that 3 switches

can u just tell me which code is use for which port?
port0
port1
port2
port3
Added after 2 hours 44 minutes:
can any one give me a easy format of asm code?
i shall design it...
i do not want to use 555 as a switche. actually i want to control the blinking rate of leds. like cd4017 ic's blinking rate of leds are controlled by ne555 ic.
that is my motto to make such circuit with the help of at89c2051.
is any one can help me out?
the ne555 will attached with...

rectify this code to blink 2 leds with 555 timer.555 is connected with p3.7 of at89c2051.

thanks for reply today i tried with uln2003. just i do add uln2003 directly with at89c2051 as 7 segment negative volt.and the other side i add another uln2003 directly. with this uln2003 i add bc557 with 4k7 and 12 volt as 4 digits positive supply.
bkz my display drives with 12 volt dc.each...
sir i made a clock with 4 digit 7 segment multiplex with a big digit display.it works but problem is in the display .bkz the digit segment is not turned off properly to display a digit. as example to display 3 we need just 5 segment to turned on.but rest of the 2 also turned on dimly. i used 4...
