I'm trying to flash an ESP8266 with the example using Platformio, but I'm getting a crash at boot:

The "ISR not in IRAM!" error message in particular points to some changes to ESP Core regarding interrupt handling, but I don't know enough to fix that.

Turns out I needed to declare IRAM_ATTR on handle_int_receive() in RF433recv.cpp:

void IRAM_ATTR handle_int_receive() {

Hello

could you post a pull-request that I could integrate to the code? This'd ease the work of others using ESP8266.

skorokithakis commented

Sure, filed #7.

sebmillet commented

integrated in the code, thanks

skorokithakis commented

Thank you!

Hello

The result would not compile due to a gap between interrupt handler function declaration and definition with IRAM_ATTR.
I just rewrote it.
It compiles well in my case (Arduino, generation on Debian bullseye)
Could you please re-test in your ESP8266 environment and confirm it compiles well?
