Rc signal help

[malc-c]

Well I just compiled the following and I get flashing LEDs (I haven't got the time this morning to hook up a receiver and test the reading of the PPM signal)

'12F675
@ __CONFIG _INTRC_OSC_CLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_OFF


DEFINE OSC 4
OPTION_REG.5 = 0 ' clock source internal
CMCON = 7
ANSEL=0

Pulselen var word ' Pulselen can be 0 - 255, 100 = 1 ms, 200 = 2 ms
Init var word ' Init used to flash LED
Clear ' set all variables = 0

Input GPIO.4 ' set pin 5 to RX signal

ReadPWM:
PulsIn GPIO.4, 1,Pulselen ' pin 4 - read high pulse length, times out after .65535 seconds
pause 15
If Pulselen < 50 Then GoTo Blink ' no signal -> blink led
If Pulselen > 75 Then GoTo solid ' signal -> Solid led
GoTo ReadPWM

Blink:
For Init = 1 To 3 ' blink led 3 times
High GPIO.1
pause 200
Low GPIO.1
pause 200
Next
pause 1000
GoTo ReadPWM

Solid:
High GPIO.1
pause 3000
Low GPIO.1
pause 200
GoTo ReadPWM
END

The only change I made was to use GPIO.4 and not GPIO.3

EDIT:
OK so I couldn't go out without testing the code to see if it reads the PPM signal.. sorry to say it doesn't detect it
