Help convert a float into code for 7 segment

[ILLIAS28]

Hi,
can anyone help me please,
i am trying to make a thermometer with a pic16F876 and a lm335 with displaying the temperature on 3 seven segment display with common anode. The problem now is how to convert the result of the Analog to digital converter of the pic in a code for the 7segment, for example how to convert 26,7 (decimal) into a code for the 7segment.
many thanks

The 'easy' way is to use the 'search' feature of this forum with the keywords 7 segment display multiplex. You will need to 'loop through' the 'display' function faster than 50 times a second to 'refresh' the display so our eyes see numbers and not the segments changing.You'll find lots of hits about this topic.There may be code in the 'code library' as well!
I'm assuming you've got 3 or 4 7Segment LEDs correctly wired to you PIC? If not, perhaps use Google to see how you can wire them up.These days it's actually cheaper to buy an LCD module though I'm assuming this is a school project.

Hi,
thank you temtronic for your reponse,,i want to make a thermometer (-30 to +50°C) ,with 0,1°C precision.I have used schematic with opamps that giges 0V for -30°C and 5V for +50°C, that i apply to the ADC of the pic16F876.
but my probleme is not with multiplexing ,i have already made some projects using pic and 7segments to display integers,but this time i want to display numbers with coma(floats).
i have used the following formula to convert, the results of the 10bits ADC of the pic,in a decimal value coresponding to the mesured temperature:
t=(((read_adc())*0.00489)/0.0625)-30; where t is a float. for exemple when the value in the ADC is B'0001111000'=120(D) that means the temperature is t=-20,6°C. And when the value of the ADC is 600(D) then t=+16,9°C
my probleme now is how to separate 16,9 for exemple in 3 chiffers 1 and 6 and 9 so i can display each one on a 7segment

Look at the "w" format in the printf function - it allows you to insert a decimal point at a specified location in your display. Use the idea Mike Walne indicated (stay with ints - life is much simpler, faster and much smaller code) then use the "w" format to insert your decimal point.
