Hi @ssaattww,

This is interesting. We've got the CI compile check for esp32-c3 in our github repo and it did pass.
We are compiling for the generic variant esp32c3 not the esp32-c3-devkitm-1 though.

Could you try compiling for the esp32c3 to maybe?
Also our CI is arduino ide base, could you try compiling with Arduino IDE?

In any case, we should investigate this.

The compile error seems pretty strange though, is should not have compiled for any library version from v2.x if this is the case.

You can also try to do a quick fix and make it compile you can navigate to these lines in your code:

Arduino-FOC/src/current_sense/hardware_specific/esp32/esp32_mcu.cpp

Lines 17 to 20 in c72f063

	ESP32CurrentSenseParams* params = new ESP32CurrentSenseParams {
	.pins = { pinA, pinB, pinC },
	.adc_voltage_conv = (_ADC_VOLTAGE)/(_ADC_RESOLUTION)
	};

And replace them by:

ESP32CurrentSenseParams* params = new ESP32CurrentSenseParams {
    .pins = { pinA, pinB, pinC },
    .adc_voltage_conv = (_ADC_VOLTAGE)/(_ADC_RESOLUTION),
    .adc_buffer = {0,0,0},
    .buffer_index  = 0,
    .no_adc_channels =0.
  };

WOW, genius to use whitespaces for an library name

lib_deps = 
	askuric/Simple FOC@^2.3.3

This will work great with Windows

libdeps/esp32c3/Simple FOC/src/current_sense/hardware_specific/esp32/esp32_mcu...

[askuric]

Yeah, it's a consequence of an unfortunate decision made at the first library release back at the day. :)

Windows should be fine with some quotation marks. :D

[EDIT]: Rolling back to version 2.3.3 of the SimpleFOC library has fixed this for me and I was able to compile for the S2 and S3 without any changes. Just if anyone else comes across this issue and needs a quick fix.

I am trying to compile for a WEMOS S2 Mini and am getting the same error. Unfortunately @askuric's above fix does not work, I just get the same error again.

Any help is greatly appreciated, thanks for the otherwise excellent software!

[askuric]

It is an interesting one, I was unable to replicate this issue. If anyone has ideas why this could happen, I'm all ears.

So another thing that you could try is:

ESP32CurrentSenseParams* params = new ESP32CurrentSenseParams();
params->pins = { pinA, pinB, pinC };
params->adc_voltage_conv = (_ADC_VOLTAGE)/(_ADC_RESOLUTION);

BTW. Rolling back to 2.3.3 version of the library should not work really, as v2.3.3 uses the Arduino-esp32 v2.x and the v2.3.4 uses the v3.x of the arduino-esp32. So when you rolled back did you roll back with the arduino-esp32 package as well?
Which version of the arduino-esp32 did you use when you were compiling for v2.3.4? Was is v3.x?

Popping in to say I'm also experiencing this problem (.pio/libdeps/seeed-xiao-esp32c3/Simple FOC/src/current_sense/hardware_specific/esp32/esp32_mcu.cpp:20:3: error: no matching function for call to 'ESP32CurrentSenseParams::ESP32CurrentSenseParams()' trying to compile for a Seeed Studio XIAO ESP32C3. Fresh project and everything, first dependency. Installed via platform.io.

Replacing the section as described above changes nothing. I still get the same...

Open to doing whatever remote debugging is needed to resolve this asap 🥲
