Hey folks. So for a beginner DIY fixed-wing flight controller, I am trying to incorporate servo values from an external receiver via SBUS [by FrSky (0-> Low, 1-> High; contrary to the standard SBUS by Futaba)] into my software.I found a good amount o...

Hey, mechatronics student here. So ive been trying to make the transition from Arduino to STM32 lately, and am a little overwhelmed by hardware-oriented programming.So I can get things like Blink running, and know my way around C good enough to have ...

A small success:After doubling the rx buffer up to 50 bytes and looking for the start flag, then transfering the index of the flag in this buffer to the SBUS-Yes/No?-Check I was able to achieve pretty regular lock-ons directly after resetting the MCU...

I understand, and after thinking about it for some time that could be one of the problems with my implementation so far aswell.A possible solution could be to, after receiving the first new data packet, wait for exactly three milliseconds (the maximu...

Thanks for your thoughts. I will try your version by myself later.In the meantime, to your synchronizing issue - how I understood it. Your issue is to recognize when a frame starts. In my version of the code, the values only get decoded if the first ...

@STea @Karl Yamashita @Tesla DeLorean @danielscm UPDATE with the logic analyzer: I finally got to take a look at what is actually leaving the receiver. The upper one is the "electronically-uninverted", raw output signal straight from the receiver. T...

So today I had the time to try out the inverted signal. Buckle up.I am inverting the signal with a p-ch MOSFET (IRF5305) using this example and verified it working as expected by testing it with an LED (Gate HIGH = Led LOW; Gate LOW = Led HIGH; 3.3V ...
