Ok guys back for round 2 of can these two talk to each other. Ive got the iflight succex-e f7 v1 stack coming. and the flysky fs-x6b reciever coming. I got all excited ordering this set up but now im worried they wont talk to each other. Im not sure the f7 stack has a inverted pad only regular ibus. If that the case cant I use ppm? IF someone tell me whats to wire where? or point me to some required reading to figure this all out that would be great.

Flysky IBUS do not use inverted UART. And with F7 MCU, it can natively invert any serial signal, so you are all good.

Awesome thank you again
