Crossing posts again:) You've answered my question. Thanks. I attach the raw data in a text file just in case you are interested. I do not of course expect you to do anything with it. thanks for all the help.

I haven't looked into the raw data before. In the raw data is the first value the height of the pulse and the second value the duration of the pulse?

By "you" I mean me accepting my limitations. I'm sure you would have the expertise to solve this if you had the time.

Hi Alan. I didn't program the raw data into the Arduino, just the binary code. I think the binary code may then be manipulated in some way or converted into the raw code by the RCSwitch.h library. I've since looked in more detail at the github on this and I will ask a few questions on their...

Hi Alan. Thanks for your continued interest with my problem. I don’t have a logic analyser or ‘scope. I got the info about the rf signal from a receiver attached to an arduino. I was then able to use this info to transmit the signal with an rf transmitter attached to the arduino and it operates...

Hi Allen. I've tried a lot of different delays around 150 but it doesn't work unfortunately. It must be more complicated than just a simple delay between each 0 and 1.Thanks for your help anyway.

Thanks for that hippy. I've looked at your code but I'm afraid it's beyond me. I think I may just go for the less elegant option of wiring the buttons on the remote control to a small relay.

Hi Alan. Sorry I didn't see your last post when I posted my last comment. You are right, it should be about 150 not 125. thanks again. I'll let you know how I get on. Regards Dermot

Oops, I'm wrong there I think. I forgot to take account of the HIGH and LOW (400/8=50) and the PAUSEUS (600/8=75) so my PAUSEUS length should be about 125?

Thanks for that Alan. So I should try the PAUSEUS command at about 250 (314/1.25) and trial and error from then on. Regards Dermot

Hi, I want to send a 433MHz signal to turn on an RF socket from a 08M2 picaxe. I have already done this using an arduino UNO R3. I sniffed the signals coming from the remote control using the arduino and the screenshot is attached. From this you can see that the first button push (turning ON...

Hi. I need some advice please on connecting an 18M2 to my PC so that I can send serial commands to it to set certain output pins high or low. I don’t need the 18M2 to reply to the PC. I do not need to be able to program the 18M2. I do that off board. I have actually done this type of thing...

Hi. I would appreciate a little help with some code please. I am using an 08M2 to control a water heater. I turn on the water heater by making pinC.4 high by simply momentarily pushing a push to make switch which is connected to 5V and pinC.4. This then makes pinC.0 go high which operates a...

Hi, I just want to flash an LED from the keyboard of a PC running Win7 64, an AXE027 cable and the PIC 08 proto board. I'm using the 08M2 chip. Here's the code I'm using: main: serin 3,N2400,b1 if b1=1 then high 4 endif pause 1000 low 4 goto main It works fine in the simulator so I'm...

Perhaps someone could clear up a slight problem I am having with Program Editor (ver 5.5.1). I am using an 18M2 with an NKM coder/decoder to send text strings to 6 different 08M2s (with NKM decoder also). I am using the serout and serin command to do this. My problem is concerned with the...
