I have 5x 7-segment display, help me

[leflau42]

I have 5x 7-segment display and i want to this to display in order active.

Example:

Data = 1 // Active First digit
data = 10 // active second digit
data=100 // active thirth digit
data=1000 // active fourth digit
data=10000 // active fifth digit

How can I do that ?

I want do 0-99999 counter application.

I am sorry for bad english.

Good place to start is here !! Learn to use the 'search' function of this website. There are LOTS of 'threads' about creating an LED multiplex display program.

Some comments..
1) the 'refresh' rate( speed of the overall loop) needs to be 50Hz or faster. Too slow and you'll see the segments change.

2) be careful selecting LED current. A 'multiplex' display needs more current than a 'static' one,so you'll need transistor drivers for each display.

and (of course), there is an example for a 2 digit display supplied with the compiler (EX_LED.C).

Like all programming, you need to subdivide.

Start by driving one display. Then how to multiplex and do two. This is then easy to expand to do five.

The splitting of the counter number into digits, is only a matter of repeated /10 operations. Look at ldiv, which gives you the quotient and remainder. Remarkably useful for this....
