Support for Arduino Due

[itavero]

Unfortunately the library currently doesn't support the Arduino Due.

WARNING: library IBusBM claims to run on avr, esp32, stm32, mbed architecture(s) and may be incompatible with your current board which runs on sam architecture(s).

Error compiling for board Arduino Due (Native USB Port).

Seems like there's something wrong with the Arduino abstraction for the Due. 🤔

PS: I'm aware that later on I will probably need a level translator to deal with the 3V3 vs 5V signals.

I did not have the time yet to look into supporting the Due and I do not have a device to test. If I make changes to the code, are you able to run tests?

[itavero]

I can perform some tests. If I find some time myself, I'll see if I can fix it and open up a PR.

[itavero]

Finally had some time to have a look.

I noticed that the serial port configuration (SERIAL_8N1) passed to Serial.begin is actually the default option (according to the Arduino website). Just removing the parameter should fix it, I think.

I'll see if I have some time in the next week or so to verify this.

[bmellink]

You are right this should be an easy fix if this is the only change needed. Would love to hear if that is all that is required.

[itavero]

Just removing the argument at least makes it compile/run again.

Unfortunately it seems that I might be running into a hardware issue with the shield I've designed. Used an TXS0108E IC to do the level translation between 5V (from the receiver) and the IOREF of the Arduino board. Unfortunately I do see the UART signals with a scope on the 5V side, but I don't see them on the IOREF (3V3 in case of the Due) side.

In other words, I've not (yet) been able to verify that the data communication is actually working.

Hello. I use the blue pill STM32F103 and FlySky FS-iA6 + IA6b. I tried the IBusBM-1.1.4 library, the examples with servo work, but those with sensor, telemetry can't solve. Can help be made? Thanks.

What do you mean by can't solve? It doesn't compile? Could you show a log?

Thanks for the reply. Sorry for the inaccuracy. Compiles, but no sensor appears on the FS-i6 display. Maybe I need to add or change something and I don't know. Thank you again.
