@nano86 ,
Your question (do you even have a question?) does not seem to be about the IDE, so I have moved your topic to a more suitable place.
Please can you read the forum guide, which @van_der_decken linked to, and take care when choosing a forum category for your questions.
Thank you.
Welcome Please keep in mind that we are not a free design or code-writing service. We’re more than happy to help with your design or code, but we need you to make an initial attempt. Please design and write your code, then post it along with an explanation of what’s not working properly.
- Show Your Work First: Before asking for assistance, make an attempt to design or write the code yourself. Share your work along with details about what isn’t working.
- Provide Clear Documentation: Since we can’t see your project, share an annotated schematic (best) or a clear drawing of your setup. Pictures are welcome, but avoid using Fritzing diagrams as they are wiring diagrams, not schematics, and are not ideal for troubleshooting.
- Include Technical Details: If there is specific hardware involved, include links to technical information. There are often many versions of similar components, so precise details are essential.
- Reference Resources: For additional help, check out useful links and tutorials: Useful Links on Arduino Forum.
Can you point out the documentation for the interrupt mode for that receiver? So far I can find almost NO documentation of any actual use of that board.
Hi ,
The receiver 433Mhz is RXB6 orSRX882S V2.0. I would like used in Interrupt with ARDUINO UNO. When a signal on INT0 the code
of interruption take it and decode . I use the librairy rc-switch.
can you help me

Follow the code that don't run ?
Have you a idea?
#define LED_PIN 13
#define INT0_PIN 2
#define RECEIVER 2
#include <avr/wdt.h>
#include <avr/interrupt.h>
#include <avr/sleep.h>
#include <avr/power.h>
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
#define CSR 7
#define INT0_PIN 2
volatile byte state = LOW;
void setup() {
Serial.begin(9600);
pinMode(CSR,OUTPUT);
digitalWrite(CSR,HIGH);
pinMode(LED_PIN,OUTPUT);
digitalWrite(LED_PIN,LOW);
Serial.println("Starting Setup");
mySwitch.enableReceive(RECEIVER); // Receiver on interrupt 0 => that is pin #2
attachInterrupt(0,INT0_ISR, LOW); // use interrupt 0 (pin 2) and run function
volatile byte state = LOW;
void INT0_ISR() {
state = !state;
Serial.print(mySwitch.available());
if (mySwitch.available()) {Serial.print("Received ");
Serial.print( mySwitch.getReceivedValue() );
Serial.print(" / ");
Serial.print( mySwitch.getReceivedBitlength() );
Serial.print("bit ");
Serial.print("Protocol: ");
Serial.println( mySwitch.getReceivedProtocol() );
mySwitch.resetAvailable();}
}
void loop() {
digitalWrite(LED_PIN, state);
}

I read the examples in the library. Your code bears a certain resemblance, except the examples do not use interrupts.
Please explain why you are trying to use interrupts.
At a glance, I would guess you have absolutely no idea when interrupts are appropriate, when they are needed, what they are for or how to use them effectively.
You do not need to complicate your sketch by using interrupts. Trying places you at a disadvantage with respect to getting anything to work.

Hi,
I wrote a programm to Alarm with two sensors temperature , humidity and presence detection. The data transmit to the central with
433Mhz. Central to my phone to WIFI. I would like rewrite the receveir 433Mhz in mode Interrupt to low conssomption. Iwould like used
Power down and timer .
This why I would like used receiver in interrupt mode.

Call the system that measures and transmits, which presumably includes a 433 transmitter module and a microprocessor, the Sender.
Call the system that gets those transmissions, which presumably includes a 433 receiver module and a microprocessor, the Receiver.
Draw a block diagram of both the Sender and Receiver.
Show all parts of each system, how they are connected and what powers each. State which of either or both need to be in low power mode. Say what would make the low power system(s) exit low power (wake up), and what would be done when awake.

Sorry, but this is very confusing. If the receiver is in low consumption mode, then it cannot receive and there will be NO data.
Thank you very much for your answer but this is not at all the way I want.
I would like to use the 433Hmz RXB6 or SRX882S V2.0 receivers in interruption with Arduino UNO on INT1.
As soon as an interruption appears, it decodes in order to process it. These receivers come from a 433Mmz transmitter that sends
: presence, temperature and humidity sensor.
The rest of the time the exchange in PW down mode, to reduce current consumption.
Do you have an idea?

I have an idea that you either have not read the documentation or you do not understand the documentation. There is NO interrupt signal generated by that receiver!
