can't compile for any ESP32 boards

[Riktor1990]

I'm using Arduino ide and esp32-c6 but also tried c2 and c3. I have error from the library. Can anybody help me ?

[ericlangel]

Hello,

could you tell me the ESP32 Core Version?
There are Problems with Core Version 3.0.0 and newer

end the exact error message, please.

[Riktor1990]

It has automatically installed 3.2

[ericlangel]

all errors are coming from the INO file. nothing from the library code itself.

Try it with the example code "SBUS2 Telemetry"

[Riktor1990]

I simply put this code: ` ```
#include <SBUS2.h>

void setup() {
Serial.begin(9600);
Serial.println("SBUS2 library works!");
}

void loop() {}
``` `

and I got this results:

same result with your example code

[ericlangel]

Yes, thats better.
Most of these issues should be solved with Core Version 2.17 (Last version before 3.x.x)

I'am not sure if C6 is already supported by 2.17
Maybe you have to change the Timer

[Riktor1990]

so I replace core version with 2.17, selected ESP32S2 dev board and tried to compile your example:

[ericlangel]

i dont know why it is not working
there are people who have got it working/compiled with ESP32-S2

i have to spend some time to make it working again. But in the least years i had no time do do it

[Riktor1990]

Would be nice to update compatibility with core 3.0

[Riktor1990]

Any updates?

[ericlangel]

no, sorry

[VID-PRO]

just bump this rquest.
Would be great to use this library with an actual ESP32 core version

[luisgarag]

I would really appreciate compatibility with core 3.0 too. Hope it can be updated!

[ericlangel]

Just had a look on ESP32 core
we are already at V3.3.1....damn time is running.

Let me try it in the next days.
Is anybody already working on it?

[Riktor1990]

@ericlangel having compatible with latest version would be awesome.

[Riktor1990]

Thanks to my friend Romolo and a bit of chatgpt I got s library working for the latest version of esp for both S3 and C6. Will upload it probably tomorrow
