convert hex code to 7 seg display

[electroicarus]

I need help to convert a code hex to 7 seg display.

 

[Styx]

thats nice....


a bit more detail abt what exactly do you need?

It is almost trivial.
You make a lookup table with ten entries, one for each digit in the range 0-9.
Each entry in the table has a one to turn on the appropriate segments.
Use the digit as an index into the table.
For each digit you want to display, output the contents of the corresponding table entry.

The circuit consists of a thermometer to meassure 0 to 99 centigrade degree ,i use a ADC0804 ,and the output goes connected to a 7seg display.I am looking for some integrated circuit that make this task.

I was confused ,was convert the binary ouput to bcd 7 seg.

Throw the ADC0804 away, and use a PIC - this can read the analogue input and display directly on the 7 segment displays - you just need to write the software to do it. But all the code you require is in my tutorials.

Hi akg, do you know where I can find datasheet on HEX-to-seven segment decorder?

Thank you

Synckewl, I think this is close to what you want:

There are several types of these legacy parts around.

thanks,
I looking for the basic gates (eg: AND) for Hex-7 segment decoder.

This pdf has the logic diagram for digits 0-9.
