Issues during compiling for ESP32 in Arduino IDE 1.8.19 #71

Closed themanfrommoon closed 11 months ago

themanfrommoon commented 11 months ago

Hello,

I have the Arduino IDE 1.8.19 and downloaded the latest .zip library sbus-main.zip I unzipped it to C:\Users\Chris\Documents\Arduino\libraries I started the IDE, choosed ESP32 Dev Module and tried to compile. But it shows following error messages.

Any idea what is wrong here? How to solve the problem?

Thanks a lot and best regards, Chris

Hi Chris,

Please note that due to the unique way that ESP32 handles serial ports, the object declaration is different, so the examples won't work as is. Documentation is here: https://github.com/bolderflight/sbus#sbusrx

An example would be:

/* SBUS object, reading SBUS */
bfs::SbusRx sbus_rx(&Serial1, 27, 26, true);
/* SBUS object, writing SBUS */
bfs::SbusTx sbus_tx(&Serial1, 27, 26, true);

Where Serial1 is a reference to the Serial1 object, 27 is the RX pin, 26 is the TX pin, and we're using inverted logic.

Hi Brian,

thanks a lot, this solved the issue. I was refering to a video I found: https://www.youtube.com/watch?v=IhlXGybLxcc&t=593s But it seems that there is a difference in the definition.

However, thanks a lot! It works fine now!

Best regards, Chris
