Hi

Not had time for a proper look but straight away there are concerns.

Interrupts should not be used as a functional "macro" so to speak. They should be as short as possible containing as little code as possible such as setting a "flag" for actioning in your Main loop or perhaps incrementing a ...

Hi Martin

Is it raining outside? I ask as you really should get out more <s>

Joking apart, this is a very handy example. Much appreciated.

Hi

I had hoped, but suspected I wouldn't, get away with using 12-w alarm cable between RKP and Panel. 4-wires for the actual RKP and the other 8-wires for the 4x4 keypad grid. I was hoping inducements on the wire from Panel to RKP (around 10v data stream) wouldn't be an issue, but it was ...

Hi

If AI was really thaaat good why are we not swamped by a never ending stream of software to do everything? If I were a professional programmer I'd be making software so fast that I would have programs to do pretty much anything and everything up for sale.

So, as a panel with communicator, which would allow an "app" is far, far ...

Hi

Totally agree on the rapid development aspect. Modules from know quality suppliers can save time and money.

Once it arrives we won't hear from Martin until he figures it out

Hi

I looked at the link and think it an expensive purchase (around £90+) especially as the associated datasheet informs it has a DB25 connector for connection to a computer's printer port and is compatible with OS's that disappeared decades ago :lol:

Clearly documentation hasn't been updated ...

Hi

I do like the idea of them for precisely the reasons you give, but decided that Matrix eBlocks offered a better fit especially as I was already using their multi-programmer.

Hi

Mine were bought cheap... So quality would be questionable.

It didn't have an antenna coil, you had to use a length of wire.

I am not condemning all of them, just that the ones I had were way too much trouble for what they offered. For little more I could get reasonable LoRa modules that ...
