I need to convert eg 2FAF080 hex to 50 000 000 dec using 4 registers casade together..

I can't think of any simple approach except to use a small 32x8 ROM containing the truth table, but that may be against your project rules.
I think you already have the right idea: convert the truth table to boolean equations by using K-maps, or simple inspection, or engineering software, or whatever approach seems easiest to you.

you should be able to do the transformation by first doing a mapping. Use the truth tables and the graphical method for each output bit.
Many years ago there were commercial ICs for this. Try looking through an old TTL data book. They will have diagrams of the logic inside the chips. 74185 is one example.

Say you are using 8 bits. Then a value can occupy a range from zero to 255.
Say zero represents 0V, and 255 represents 5V. Then you can use a simple proportion to translate any value to a voltage.
To model this in electrical terms, each analog voltage is derived by sending 5 volts through resistors of different values.
Similarly each bit is weig

Convert this number to three digits (bcd), 4 bit nibbles.
Use these three digits one by one, to convert it to ASCII just add 48 (decimal).
Send this to the LCD display. Use appropriate order of these ASCII codes to display correct value.
