divide

Maybe you can do something like this . . .
First, find out when x increments by 1, what is increment in frequency (call this the step size)
Second, find out what is the frequency when x = 1 (call this the minimum frequency).
Then to find actual frequency from x you can do some math like below:
actual frequency = minimum frequency + (x * step size)
Now you can print the actual frequency on the lcd using LCDOUT (assuming you are using a HD44780 based LCD display).

Assuming:
1) You can use LONG variables
2) You are looking for the time of each period

Freq VAR LONG  ' Length of time for each period

SELECT CASE x
   CASE = 1
      LCDOUT "001.000 Sec"
   CASE <=1000
      Freq = 1000000/ x
      LCDOUT DEC3 Freq/1000,".",DEC3 Freq," mSec"  
   CASE ELSE
      Freq = 1000000000/ x
      LCDOUT DEC3 Freq/1000,".",DEC3 Freq," uSec" 
END SELECT
