Re: HC-12 433 mHz module + Ard + Kerui PIR
Hi Martin B5 or D2? --------- D2 is connected to INT0 by default, you are correct. I didn't use B5 at all, as I used ssd1306. I have to update the 'I have to change pin B5 to pin d2'. I didn't use B5 as an input, just used B5 (calculation icon) to change it to D2 to pull the input high. Saved some t...

Re: HC-12 433 mHz module + Ard + Kerui PIR
Hi Martin Re: Did you get the code I posted to return anything? I have to change pinB5 to pinD2 in your code as D2 is connected to output of SYN470R Rf chip. I run this code on Nano a few times by using the Tx remote controller with 24-bit code (1527 protocol). No return. Re: It should be possible t...

Re: HC-12 433 mHz module + Ard + Kerui PIR
Thanks Martin
On Ard board LED B5 for debugging only: Understood
-------------
When I read the RCSwitch library I noted that after 1st high was detected system was waiting for the 2nd High.

Re: HC-12 433 mHz module + Ard + Kerui PIR
I am not sure how to run interrupt on Nano D2 input to check on 350uS if interrupt freq is 15Hz?
15 Hz = 66666uS
-------------------
Need to read again about mentioned by you about sampling...

Re: HC-12 433 mHz module + Ard + Kerui PIR
Hi
What to do?
One way -> use counter
2nd way (as you suggested) ->sample in the middle of a time period and take this value.

Re: HC-12 433 mHz module + Ard + Kerui PIR
Hi Nano should be able to decode the full 24-bit string though. It does. I used RCSwitch library and it works. Nano does a job. 350uS pulse length is the length of a bit / 4... I believe it is. If one bit = 4 clocks, the Preamble High pulse = 350uS+31 Low(350*31), the High bit pulse = 350*3=1050uS+ ...

Re: String to num 1st Zero lost
What about using Right$ in a calculation?
-------------------------------------------------------
Sure... but I wanted the integer as 077.
The only way of displaying a leading zero is in a string format
Looks like I have to flag the converted integer 77 (from "077" string) as negative.
Thanks

Can you ask your friend to 'ping' the bus before
the program will access sensor N6?
