6-digit 7 segment 5 displays interface with 8051

[Rk_on_edaboard]

I want to interface five 7segment displays with 8051
each display is of 6 digit.
It is possible using only one 8051 ? if yes then how?

Total 30 digits to interface or glow using one microcontroller 8051.

8051 is not enough for your application, Because it's less port pins.

You need minimum 38 pins, 8051 have 32 I/O lines.

So you go with some other controllers.

Refer the given. How to interface the 7-segment with micro controller

It can be also done with external demux or decoder of 1:32 and with 13pins of 8051. but the refreshing rate will be poor.
you can do in 24 pin mode with two 1:16 line decoders.

If you feel more comfortable with the 8051, you can use it. also if you take any controller you will do in the same way.

Yes, I Agree with Venkadesh..
