RCTIME not getting a result

[tasmod]

I decided to make another 'chicken door' again this time using a 16f84. As it has no ADC for the LDR I tried using RCTIME but all I get is either 0 or 1 as the result, is it my code?

I tried putting one end of the LDR to 5v the other to a .1 cap which then goes to the pin.
I tried LDR to pin , other end to cap to ground.

Both give same result.

I'm using:-

LOW PortB.0
PAUSE 10
RCTIME PortB.0,0,LDR
LCDOUT $FE,$80,LDR

OK, no-one answered my simple question.

Fortunately a YouTube video answered it although it's in Hungarian I think.

The PBP manual doesn't make it very clear but the video shows that two pins are necessary to use RCTIME ?
One to charge up the cap the other to measure the discharge.
One via a 1k resistor the other via a 1Meg resistor and .1 capacitor.

No, only one pin is used



' CAP POT

' PIN-----/\/\--'

But you probably will not be happy with the results. Use a MCU with ADC.
