Arduino Nano read SBUS Receiver tutorial 

No. TTL logic level on the Arduino board cannot read the sbus logic level directly via TX, RX pin.

yes. It can. But I don't think you need this for a basic airplane. This will be useful for doing some extra work such as "automatic balancing" before sending your control signal from Rx to Motor/servo.

I've made a tutorial.. feel free to check it out.. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Zf-I-a3_YQE.html

I haven't try with stm32

I haven't tested with 74HC04 so i don't know it will work or not. But i think i should work

@@TheHLab oke i will try it. Thnx

@@tanoryjakaperdana1419 oh thnx il try that to👍

Hi. Because the logic level is reversed with logic level of Arduino.

@@TheHLab Hi, thanks for your reply. Am interested to understand more about this. Do you mean that the pwm signal is opposite ie a low pulse instead of a high pulse? Could the library code be modified to account for the inversion so that an extra circuit is not required? Thanks :)

@@cliveminni Thank you, i'm also curious about this. If you can invert the signal in code and eliminate the circuit please let us know, it would be nice optimization!

I haven't tried with ibus.

According to Bolder Flight Systems library, you can do it. However, I've never tried it yet.

It's powered from Android via SBUS channel.

I don't know much about rm+ but if it support SBUS i think it can be use with my circuit (some RX have default revert so we don't them in this case). Read all 16chs: actually my demo code read all 16channel but my Tx-Rx only have 6chs. Arduino Uno: yes, Of course.

thanks😁👍 xm+ is frsky sbus by the way

Hi arw you got it, ı will try

@@omhobby9481 Hi, did you get it to work?

I notice the servo doesnt move 180degrees, i tried this code and mine doesnt either. Any idea how to fix that?

In theory it should work.

You can calibrate your ECS without this circuit, directly use Receiver is more easier

Because I don't have pwm receiver, i choose this way to calibrate my esc...so could i use it?

Yes. You can calibrate ESC by arduino code. I've tried it before

Oke...thank you for your attention...have a nice vlog and nice to meet you...🙏🙏

To support Arduino Nano, at the time I made this video, it haven't support Arduino Nano yet. Just like a trick

@@TheHLab well i think it worked on a mega 2560, had some errors but seems to be good now. Had no time to test it with hardware tho

Toy

I think yes.

@@TheHLab dude ı use frsky taranis x9 lite and xm+ receiver, can ı make like you

and how can add auto matic balancing, are you make video this subject

It's powered from Android via SBUS channel.

I haven't tried with ibus yet.

@@TheHLab right now so many members r using ibus which means flysky tx and rx so plz make a video on that probably u get more subscribers

Thank for your suggestion. I will try

Correctly, this Arduino circuit decode SBUS signal from MC7RB Receiver to PWM. And I used one servo to demonstrate that signal was decoded correctly. Thank for watching :)

what issue are you facing?

It wont compile with a nano every, but i use another now. Is it possible to receive with sbus, see the jnput and send it with sbus instead of pwm?

#include "SBUS.h" #include #define NUM_OF_CHANNEL 16 SBUS x8r(Serial); Servo servo1; Servo servo2; Servo servo3; Servo servo4; Servo servo5; Servo servo6; // channel, fail safe, and lost frames data uint16_t channels[NUM_OF_CHANNEL]; bool failSafe; bool lostFrame; void setup() { // begin the SBUS communication x8r.begin(); servo1.attach(12); servo2.attach(11); servo3.attach(10); servo4.attach(9); servo5.attach(8); servo6.attach(7); } void loop() { if(x8r.read(&channels[0], &failSafe, &lostFrame)){ servo1.writeMicroseconds(*(channels+0)); servo2.writeMicroseconds(*(channels+1)); servo3.writeMicroseconds(*(channels+2)); servo4.writeMicroseconds(*(channels+3)); servo5.writeMicroseconds(*(channels+4)); servo6.writeMicroseconds(*(channels+5)); } }

@@TheHLab Could I adapt this code to control two 9v dc motors? Also, what code would I want to enter into the loop if I wanted to see the sbus data through the serial monitor for each channel?

Could I adapt this code to control two 9v dc motors?: Yes. Just connect your Motor driver (could be L298N) to PWM pins, for example pin 11 & 12 and use my code to control via channel 1 and 2. To print sbus data to serial monitor: Serial.println(*(channels+0)); // 0 channel 1, 1 channel 2...

@@TheHLab hi, thanks for your fast reply! I just tried your suggested code on my setup but I'm getting an issue where the serial monitor either prints out a bunch of 0's which do not change with control input. When I change the baud rate of the Serial.begin() code it changes from 0 0 0 0 0 0..... to a bunch of ????????? question marks. What do I need to do to accurately parse the incoming data into my serial monitor? I'm using a frsky xm+ receiver, does this make a difference? it's still sbus

Sorry for my mistake. Because of Serial was used for SBUS at line: SBUS x8r(Serial); so it can't be used for USB port anymore. I think you could try with another Arduino board, which have multiple Serial ( Serial, Serial1...) such as Arduino Mega and change to used Serial1 for SBUS: SBUS x8r(Serial1); while using Serial for Serial Moniter. Hope it work!
