I connected the TX pin of Serial1 to the base of transistor and the SBUS RX pin of my flight controller to the collector. And I tried to send SBUS packets to the FC by using the example sketch, which didn't work.
I tried to read the source code the "write" function and wrote the sketch below.
It did make a difference on the receiver setup page (apm, mission planner). I noticed that the value of each channel did change correspondingly when the value was changed in my sketch. Sadly I could never sent the desired values. I took note of what I wanted to send and the results.

And when I was using the F4 flight controller, it didn't seem to receive anything...
