This is a binary-to-BCD decoder made with a PIC18F452. The input is a binary double word (32 bit) and the output are five bytes, two decimal digit per byte (10 decimal digits).
The visualization is made with ten "TIL311" displays.
The switch shows on displays the hexadecimal input or the converted decimal output.

Four 40Pin PICs to make a BCD conversion?

What a waste of resources.

You can do the same with about 8 TTL or CMOS logic circuits and for less money and cero programing cost.

I don't think so.

With 8 IC's i can make a 5-6 bit conversion, but this is a 32 bit conversions. It needs many more IC's.

Try....

HEX input, not DEC input? I was wondering how you were able to wire the keypad input into the circuit or just the basics of how that part works. Thanks.

wow, you wired that whole thing by your self? How long did it take you lol.

The multiplex mode....

The PIC was engaged to carry out the conversion many times per second. So were needed operating systems display (CP82C55).
