Support esp8266

[maragelis]

Is there any chance this can work with an esp8266

aslong as you provide 5v to the radio receiver, see no reason why it shouldn't work

[maragelis]

I am giving it 5v, but cannot seam to get it to work. I am using gpio5 (D1) but no data is coming through. Even tried you demos, but still nothing. On arduino uno everything works fine.

Ok got it working had to change the below function

bool HomeGW::setup(uint8_t pin) {

HomeGW::pin = pin;

pinMode(pin, INPUT);
digitalWrite(pin, LOW);

attachInterrupt(pin, HomeGW::handleInterrupt, CHANGE); // 1 = PIN3

return true;
}

Esp has interrupts on all pins and names them with pin numbers. Thanks

Good to know 😊

So only the test for pin 3 or 2 was failing ?

If you make a PR with a test that covers Arduinos and ESP8266 I will accept it.

[maragelis]

You where also doing a pin-2 on the attachInterrupt() so that had to change to.

Hi maragelis.
Can you help me? Like you I have got this to work fine on a Uno - but not an ESP8266.....
Looking at homeGW.cpp there is #if defined(ESP8266)
As far as my knowledge of Arduino is concerned, I should have a #define (ESP8266) in my main prog.
But that throws up an error - macro names must be identifiers
If I include #define ESP8266 nothing seems to change - and I just get garbage.
I am using hass_serial.ino (with the JSON stuff removed)

It would seem you have got this to work (with the fix you posted) so any pointers would be a great help.

BTW - my 433Mhz rx works fine on 3.3v!

Many thanks

defined(ESP8266) is an AVR directive built into ESP8266/Arduino
see esp8266/Arduino#2391

Check out my project for ideas https://github.com/maragelis/433MhzToMqttBridge/blob/master/MhzToMqtt.ino

Hi maragelis.
Thanks for a swift reply.
I;m no arduino expert..... so are you saying if I select ESP8266 in the IDE prior to compile that ESP8266 will be automatically defined?

I will certainly check out your project....
Again - many thanks...

Works perfectly on atmelavr but I'm not being able to get reading from the same radio on an ESP8266 platform (wemos d1).

As my arduino/esp8266 knowledge is not deep enough to understand what was writtner here, my question is if i have to replace function setup on homegw.cpp file?

bool HomeGW::setup(uint8_t pin) {
HomeGW::pin = pin;
pinMode(pin, INPUT);
digitalWrite(pin, LOW);
attachInterrupt(pin, HomeGW::handleInterrupt, CHANGE); // 1 = PIN3
return true;
}

Thanks

before attachInterrupt add delay(2000);
it will fix issue with restart
