433MHz RF remote control

Hi There,
I tested another lib for the RF remote control.
I use the RC switch from this link.

https://github.com/sui77/rc-switch

It is pretty easy by changing the initial pin to pin PA7( or other pin).

mySwitch.enableReceive(PA7);

Received 5592332 / 24bit Protocol: 1
Received 5592512 / 24bit Protocol: 1
Received 5592323 / 24bit Protocol: 1
Received 5592368 / 24bit Protocol: 1

From the “Receive Demo.pde” , The output from Serial is above for button A , B , C ,D.

Have Fun.

Thanks for letting us know that library works.

I have used it several times on AVR for both sending and receiving, and I have contributed to the forum for that lib as well, as I worked out how to use it was the WattsClever remote controlled mains sockets

I have Maple mini, and reciever MX-RM-5V, connect it to PA7.

Code
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
.
.
.

mySwitch.enableReceive(PA7); // Receiver on interrupt 0 => that is pin PA7

//НАЧАЛО бесконечный цикл while (true)
while (true)
{

if (mySwitch.available())
{
tft.print(F("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"));

output(mySwitch.getReceivedValue(), mySwitch.getReceivedBitlength(), mySwitch.getReceivedDelay(), mySwitch.getReceivedRawdata(),mySwitch.getReceivedProtocol());
mySwitch.resetAvailable();
}

}

Did you get at least a 433.xx resonator on the Rx or Tx board (looks like a small smd crystal with 3 or 4 pins)?
If not, your rx or tx could be fully off the frequency..
Do you power the MX-RM-5V with 5 or 3.3V?

I have 2 recievers boards, and try it both.

Do you power the MX-RM-5V from 5 or 3.3V?

4,3 V and try 5V but nothing

Try 5V and measure the output signal level, it should not be bigger than 3.3V.
Or, put a 3k3/2k2 resistor divider in the series with Maple input.

First, you must see the rx output data pin “does something” when you press a button on the tx. On an o’scope you will see a pulse train with levels like near 0 up to 4V.
Then you may start to mess with software.

and why is incompatible, first time i see it

I try it on Arduino Uno r3, but it do not receive. I have Pulse train from DAta RX.
Maybe RCSwitch LIB support only some protocols, and do not show what received unsupported protocol?

if (mySwitch.available())

must triggered after received something.?????

ok,( MX-RM-5V ) need to adjust R13, with out sending data from transmitter – no DATA in out of receiver!!!!
R13 1Мом fix the problem.
