You will probably need to provide more details, exactly which code is running and when does it happen?

[hydrafi]

sorry,
I tried IRrecvDemo example and with esp32 run correctly, with esp32c3 reboot continuosly after irrecv.enableIRIn(); istruction ...
thanks

My guess is that there is something not quite right with the ESP core library for the ESP32-C3.
I don't have a C3, so I'll look at ordering one.

As you said it is working on the normal ESP32, I'm going to have to ask you for all the exact versions of this library you're using, and the relevant core library versions for BOTH your ESP32 and the ES_32-C3 so a) it can be replicated, and b) determined if it is our library's code that is the problem, or c) If it's a bug in the C3 version.

Also, can you please add the following to the "IRremoteESP8266.h" file:

#define _ESP32_IRRECV_TIMER_HACK false

Put it after:

IRremoteESP8266/src/IRremoteESP8266.h

Line 46 in 6bc095a

#define IRREMOTEESP8266_H_

Also can you please confirm/check what the values of the following #defines are, or if they are defined at all:
ESP32, ESP_ARDUINO_VERSION_MAJOR, ESP_ARDUINO_VERSION_MINOR, ESP_ARDUINO_VERSION_PATCH

[crankyoldgit]

Oh, and what ESP32-C3 dev board are you using, so I can try to get the same?

[hydrafi]

Oh, and what ESP32-C3 dev board are you using, so I can try to get the same?

ESP32-C3-DevKitM-1

library -> Arduino by Espressif System 2.0.2

I will try your proposal and update you

[crankyoldgit]

Oh, and can you please try installing/running the same example code without anything plugged in to the board, other than the USB cable of course. Just to eliminate any hardware/wiring issues.

[crankyoldgit]

I've ordered a board, but that will take weeks & weeks to arrive.

[crankyoldgit]

ESP32-C3-DevKitM-1

Also, what is the version of the IRremoteESP8266 library?

[crankyoldgit]

@hydrafi Have you tried the above?

[crankyoldgit]

The ESP-C3 board I ordered arrived today.
I'll try to test it out soon.
Did you try the earlier suggestions?

[crankyoldgit]

I just tried building this and got an error message of:

Error: This board doesn't support arduino framework!

@hydrafi Can you please post the platformio.ini file you are using to build with so I can replicate it?

[hydrafi]

Hi, sorry for my inaction, I use Arduino, Visualmicro or Visualcode tomorrow I will dedicate a slot, I will do the tests and I will send you everything, thanks a lot Massimo Il 01/03/2022 09:59, David Conran ha scritto:

Hi,
I tried again with #define _ESP32_IRRECV_TIMER_HACK false, no change ....

In Arduino IDE 1.8.19 I have installed library -> Arduino by Espressif System 2.0.2 and no problem with ESP32C3 dev module
this is the ref to install that
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json
Visualmicro & Visual code works too
I do not know if platformio support C3

example used is IRrecvDEMO and the target has only 2 components, ESP-kit + IRreceiver. Only my change is the pin used to IRreceived ..
my IRremoteESP8266 version is 2.8.1

[crankyoldgit]

Good news: I can kind-of replicate the crash. Bad news: I have no idea what is causing it yet.

[crankyoldgit]

I've seemed to have narrowed it down to the pinMode() call in IRrecv::enableIRIn(), not sure why that is causing the device to go crazy.

[crankyoldgit]

I think I've found a/the problem. It is the use of GPIO 14, that seems to be used by the USB connection on the dev board for C3 devices.
It causes the board to crash by making that pin an INPUT. Probably causing a short circuit/current loop etc.

Using:

const uint16_t kRecvPin = 10;

Seemed to get to the main loop.

@hydrafi Can you please test that out?

[crankyoldgit]

FYI: GPIO 10 is Pin 11 on the board.
see: https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/hw-reference/esp32c3/user-guide-devkitm-1.html#j1

[crankyoldgit]

@hydrafi Can you please try the code in branch: https://github.com/crankyoldgit/IRremoteESP8266/tree/espc3 / PR #1768 ?

Please let me know how it goes.
You will need to use the new versions of the examples. The core of the library has not been changed.

I've partly tested this on my ESP32-C3 board. I've not tried to capture an IR signal on it yet, but it doesn't crash/boot-loop like it did, thus I'm considering it fixed.

[crankyoldgit]

As a note for those trying to use PlatformIO to build the examples on an ESP32-C3, you need something like the following in the platformio.ini file:

[env:esp32c3]
platform = espressif32
platform_packages =
    toolchain-riscv-esp
    framework-arduinoespressif32@https://github.com/espressif/arduino-esp32.git#cbcba53
    platformio/tool-esptoolpy @ ~1.30100
framework = arduino
board = esp32dev
board_build.mcu = esp32c3
board_build.variant = esp32c3
board_build.f_cpu = 160000000L
board_build.f_flash = 80000000L
board_build.flash_mode = dio
board_build.arduino.ldscript = esp32c3_out.ld
build_unflags =
    -DARDUINO_ESP32_DEV
    -DARDUINO_VARIANT="esp32"
build_flags =
    -DARDUINO_ESP32C3_DEV
    -DARDUINO_VARIANT="esp32c3"
  ; -D_IR_LOCALE_=en-AU

[hydrafi]

I had used gpio3 however I tried your new example sketch with gpio10 but nothing has changed. I don't know platformio, can you post the bin file that I try it?

[crankyoldgit]

@hydrafi Try this:
IRrecvDumpV3-espc3-20220305.zip

[hydrafi]

Hi, good news.
Your bin run.
Not clear why?
I debugged / traced verifying that the statement "timer = timer Begin (_timer_num, 80, true);" in line 455 of IRrecv.cpp which defaults to 3 in _timer_num crash.
ESP32C3 has only 2 timers (https://docs.espressif.com/projects/arduino-esp32/en/latest/api/timer.html).
If you set 0 or 1 my compilation works too.

[crankyoldgit]

That's great to know. I'll look at the timers used soon as well.
It could be that I'm using a slightly different version of the ESP32 Arduino core. Not sure why

[crankyoldgit]

@hydrafi I've updated that branch & PR #1768. This time there is a library change. Can you please build against that version of the library.
It should ensure that only a timer of 0 or 1 is used for an ESP32-C3, thus hopefully fix the issue you're having.

[crankyoldgit]

@hydrafi Chasing up on this. Can you confirm if the recent changes now construct a binary for the ESP32-C3 that doesn't crash from the examples without any modifications in your build environment/hardware?
i.e. Can we safely merge this into the master branch?

[hydrafi]

ok

[crankyoldgit]

FYI, the changes mentioned above have now been included in the new v2.8.2 release of the library.

[Jason2866]

@crankyoldgit I made a custom setup for Tasmota for Platformio to use the C3, S2 and S3. Feel free to use :-)

Thx for your awesome work with IRremoteESP8266
