how to display 20 bit data on seven segment

[divya]

 

 

Hi 

 

i have interfaced ADS1230 with 89c52. 

 

the ADC gives 20 bit digital output. this 20 bit digital output has been saved in a variable “temp”. Now i want to display this 20 bit data on seven segment. please help me and tell how can i do this..

Hi Divya,

There are seven segment driver ICs available which can directly take digital input. Just google it.

its not possible to show the 20 bit in a single seven segment display maximum bit to display for a seven segement display starts from 0 to 9 . combination of two seven segment cascaded arrangemetn is possible to implement 20 bit .

i have 6 seven segments interfaced with the controller. how do  i have to make this conversion for displaying the 20 bits saved in the variable to the seven segment?

Hi Divya,

“i have 6 seven segments interfaced with the controller”.

Please post the circuit of the same, so that we can help you.

The SSD looks simple, but it is the most difficult thing to be coded as far as my experience is concerned. Also the controller can’t do other tasks while running the display. The reason is that it should be refreshed at a high rate and the number of SSD increases, the speed should be made high. You can’t easily get it right if you are a beginner!

That’s why suggest you to look for SSD driver ICs.

Anyway if you post the circuit, I’ll try to explain how to code it.
