Nexa control - Bruce

[Dennis]

Hi Bruce if you are reading this please could you reference thread...
[HTML]http://www.picbasic.co.uk/forum/showthread.php?t=10347&highlight=nexa[/HTML]
I have the exact same modules at home and was hoping you could help me out with the matching receive code. I would like to have a modified PIC receiver for my security gate.
I spoke to Fredrick who can't praise you enough because his tx is still working 100% he also told me he only has the tx section too but would love the rx section as too wants to modify his.

Would appreciate any help

kind regards
Dennis

Well, since you already know precisely how long each pulse width is for each data bit
being sent, and how many total bits are in each packet, it's just a matter of using PULSIN
in a short loop to read inbound pulses.

Put something together. If you get stuck, post what you have here, and I'm sure someone
will offer help with it.

This thread http://www.picbasic.co.uk/forum/showthread.php?t=6581 has a code example using PULSIN to decode an 8-bit Holtek encoder, which has a data output similar to the NEXA where 2 pulses are used for form a single bit.

Thanks a million

Will get going on it and see what I come up with ...

I have some RF modules from you , I bought them about 4 years ago over the internet. tlp-434 and RLP-434...
Was just wondering if they would indeed work for this type of setup or not.

kind regards

Yep. They should work fine.

Now to get my head around the pulsein/pulesout thing !
It's all about crucial timing not so ?
With that in mind would it be a serious mistake to use the internal oscillator ?

Kind regards

Internal osc should work just fine with PULSIN.
