Rc signal help

Gecko and Dan are one and the same

soooooo,

If Pulselen < 50 Then GoTo Blink ' no signal -> blink led
If Pulselen > 50 Then GoTo Solid ' signal -> Solid led

that's all !!!

Something is really screwed up !

ReadPWM:
   pulsin GPIO.4,1,Pulselen                  ' pin 3 - read high pulse length                  
   If Pulselen  > 0  Then GoTo Blink      ' on  -> blink led
   GoTo ReadPWM

I've tried various settings for "if pulselen >" and it makes no difference, the code just won't jump to the blink led section. I also tried the RCTIME as it mentions in the manual that RCTIME measures the time it takes for a pulse to change state from on to off.. even that didn't work.

Dan (Gecko) - maybe you can use your 16F628 as a test bead and hook up your LCD to display the value of pulselen for a 1ms signal, and 2ms signal and then use that to set the threshold ?

Nothing surprising Malc ...

If Pulselen > 0 Then GoTo Blink ... means the only "Solid led" possibility is Tx ON, but no frame sent ( pupil switch ON, but
no pupil Tx )

Too Bad !!!

Now, ... understand you've received info from Gecko ... and we didn't !!! .... difficult to understand each others then !!!

[malc-c]

varified that the output from the RX is being received on input pin of the PIC and still no joy

[Acetronics2]

Malc,

An Update of this Thread would be welcome ...

We do not know any more what is looked for, and what Gecko really wants ...
or what YOU're looking for.

Thanks for Everyone

We've been communicating via e-mail when he started his pellet counter, and it was me that suggested he joined this forum... not received anything on this project so you are still in the loop !

Im in US so was sleeping... Your in the loop you have missed nothing other than Malc knows my name lol.

I want to be able to get the RX signal and tell weather the stick is left or right or center and flash the LED acordingly. Thats it, nothing overly complicated. I just got up and will be checking the latest code. From what I read from Malcs response its still no go.

Ok to make it make more sense lets think of it as a blinker on a car.
Left on the stick will cause the 1 blinker to blink right on the stick will cause another to blink and center will cause none to blink.

I have been just trying to blink or solid a led but that may make more sense.

Malc I will try the LCD and see what I get. Wish I had a serial connect some how.

Hi,

I am not a big fan of PULSIN. It is sometimes hard to know what is happening so I prefer setting up timers to measure things myself. There are several posts in this forum how to use timers and it is really not that hard. If you pick a 16 bit timer and set the prescaler to 1:1 you can measure up to 65 ms without overflowing at 4 Mhz and 2.55 ms with a 8-bit timer and getting a nice resolution. The RC signal shouldn't be hard to catch this way.

If you have tried everything else, Timers might be worth a try.

Ok im feeling really dumb but may have it worked out. Doing some tests
