Propeller Display using AT89C2051

hi vssmartboy
try this code i edit it according to keil instead of RIDE
try it and tell

in place of 470ohm resistive ntwrk can i use individual 470ohm resistance?

yes that r only resistors u can use any type as ua want individually or in the form of array

Thank u very much MAJOKA bro for help,bro plz make hex and asm file of this project code in keil with text "LOVELY INSTITUTES(LIT)"...

MAJOKA bro i read ur program which u made for me..thanx..u only changed letters frm propeller display to lovely inst..bro plz tel how u create .hex file in keil..and tell can i display anything by replacing letters..plz tel the steps to create .hex file of this code in keil..thnx again

hi!
there is no available moc7811 here in our country so I substituted it with a photo-transistor(wpt 440f) and an IR diode set up such that an interrupt occurs when the phototransistor detects the IR.

How can I invert the interrupt? for example, when the transistor detects and IR signal, it will go high.

hi laichee
normally photo transistor goes low when it detect light u can add a npn transistor to invert it further or u can use a not gate also to invert it
exact diagram is in the project zip file u can see that that also inverting a logic ru see that

hi vssmartboy
the original project coding is in RIDE IDE
to edit in keil is not so difficult
ist line of including 8051 file u have to remove that in keil and compile it
edit the message as u want and compile it
hex file is created now according to new code
tell me ever u built any project in keil or not
then i guide u according to that

Aslamwalaikum bro..No majoka bro,its my first project in keil or embedded..bro can u made a program who can display clock rather than any text.. And plz also made program in C of that program u made for me..

ur talking for the same project or another clock that display it on simple 7-segments

Bro m talking about same project..if we wana display clock wid this project..

actually i do not see he detail coding of this project and i think it is in fact a clock because its title is propeller clock
