Minimalist Numeric Display ideas

[languer]

Question to Langure...
Have you used these displays? Are they allready set up for serial communication? What baud?
They are amazingly inexpensive... great find!

Thanks

Just to add to the "idea pool" of minimal digit displays.

Usually i'm too lazy to wire a seven segment display to a protoboard design just to debug a value in a variable.
For that reason, i've made a small subroutine that blinks a led according to the value of a variable, For fast and ease of translation the variable is divided in its digits. Easy and fast to read.

Here is a code sample:

'["asynchronous serial protocol for human eye..."]

'[put your port configs and more here]
'---- Define Variables part
x var byte
Y var byte
n var byte

'---- Main program
main:

x = 123 'any value
gosub blinkled 'blink led according to X

goto main

'--- Subroutine part
blinkled:  'blink led on GPIO.1 according to X value
    if x > 99 then '1st digit
        y = x dig 2
        gosub blinkloop 'blink the digit
        gpio.1 = 1 'one final large blink to separate digits
        pause 1000
        gpio.1 = 0
        pause 400        
    endif
    if x > 9 then  '2nd digit
        y = x dig 1
        gosub blinkloop 'blink the digit
        gpio.1 = 1 'one final large blink to separate digits
        pause 1000
        gpio.1 = 0
        pause 400
    endif    
    y = x dig 0    '3rd digit 
    gosub blinkloop 'blink the digit
return

blinkloop: 'blink subroutine
    for n = 1 to y 
        gpio.1 = 1
        pause 100
        gpio.1 = 0
        pause 400
    next n
return

Actually i've made a wrist clock out of it with just 2 leds as a display
Enjoy
