convert a decimal variable to a string

Hello.

This is probably a very simple question, but i cant seem to get it to work.

I have an LCD driver, that only takes null terminated strings, and it works great.

But i want to interface the ds1302 with it, and it puts out decimal values. I have tried to use simplenumbers, dec function, but no go.

example:

rtc.readTime( @hour, @minute, @second )
LCD.Goto(0, 0)
SN.decstr(second)
LCD.writestring(second)
waitcnt (30_000_000 +cnt)

I'm not familar with simple numbers but don't you have to grab the pointer results of decstr()?

myptr := SN.decstr(second)
LCD.writestring(myptr )

oh sorry, i uploaded the wrong routine, that one is a private routine inside of serial numbers, it should be just SN.dec..

Thanks for your reply, though, didnt work either..

Maybe there is someway to break out the single numbers of this these numbers? I can send them individually with writechar function..

ie:

12 will be
1
2

You really should post all your code

Maybe this will help. Replace the PST with the LCD object.

CON
  _clkmode = xtal1 + pll16x     
  _xinfreq = 5_000_000

VAR
  long  ptrNum

OBJ
  pst   : "Parallax Serial Terminal"
  nums  : "Simple_Numbers"

  
PUB Main | myNum
  pst.start(115200)
  Pause(500)

  myNum := 12345
  ptrNum := nums.dec(myNum)

  pst.str(String("Number to String: "))
  pst.str(ptrNum)
  pst.char(13)


PRI Pause(Duration)  
  waitcnt(((clkfreq / 1_000 * Duration - 3932) #> 381) + cnt)
  return
