Problem with data reception after iBus

[stryjekryjek]

Hi friend,
I have such a problem, namely I want to receive data via iBus from the flysky ia6b receiver.
The problem is that I get all 0 instead of specific values.
The same code uploaded to ArduinoMega works without a problem and with stm32 it does not want.
I tried on the STM32F411 / F401 blackpill, NUCLEO-F401RE plates and all the time I have only zeros.

Ch0: 0 ---- Ch1: 0 ---- Ch2: 0 ---- Ch3: 0 ---- Ch4: 0 ---- Ch5: 0 ---- Ch6: 0 ---- Ch7: 0 ---- Ch8: 0 ---- Ch9: 0 ---- Ch10: 0 ---- Ch11: 0 ---- Ch12: 0 ---- Ch13: 0 ---- Next
Ch0: 0 ---- Ch1: 0 ---- Ch2: 0 ---- Ch3: 0 ---- Ch4: 0 ---- Ch5: 0 ---- Ch6: 0 ---- Ch7: 0 ---- Ch8: 0 ---- Ch9: 0 ---- Ch10: 0 ---- Ch11: 0 ---- Ch12: 0 ---- Ch13: 0 ---- Next
Ch0: 0 ---- Ch1: 0 ---- Ch2: 0 ---- Ch3: 0 ---- Ch4: 0 ---- Ch5: 0 ---- Ch6: 0 ---- Ch7: 0 ---- Ch8: 0 ---- Ch9: 0 ---- Ch10: 0 ---- Ch11: 0 ---- Ch12: 0 ---- Ch13: 0 ---- Next
Ch0: 0 ---- Ch1: 0 ---- Ch2: 0 ---- Ch3: 0 ---- Ch4: 0 ---- Ch5: 0 ---- Ch6: 0 ---- Ch7: 0 ---- Ch8: 0 ---- Ch9: 0 ---- Ch10: 0 ---- Ch11: 0 ---- Ch12: 0 ---- Ch13: 0 ---- Next
Ch0: 0 ---- Ch1: 0 ---- Ch2: 0 ---- Ch3: 0 ---- Ch4: 0 ---- Ch5: 0 ---- Ch6: 0 ---- Ch7: 0 ---- Ch8: 0 ---- Ch9: 0 ---- Ch10: 0 ---- Ch11: 0 ---- Ch12: 0 ---- Ch13: 0 ---- Next

Code:

#include <IBusBM.h>



IBusBM IBusServo;

//Arduino Mega
//HardwareSerial Serial2(17,16); 

//                      RX    TX
//HardwareSerial Serial2(PA3, PA2);
  
void setup() {
  Serial.begin(115200);

  IBusServo.begin(Serial2);

}

void loop() {
  ibusServo();

}
//
//
//

void ibusServo()
{
 // show first 14 servo channels
  for (int i=0; i<14 ; i++) {
    Serial.print("Ch");
    Serial.print(i);
    Serial.print(": ");
    Serial.print(IBusServo.readChannel(i));
    Serial.print(" ---- ");

  }
 Serial.println("Next");

  delay(1000);
}

Has anyone encountered such a problem ??
I tried to download only Stm32Cores on a clean installation and IbusBM also does not work ;(

The worst part is that exactly a year ago, maybe one and a half everything was working on the blackpill STM32F411.
And I did some dumb updates a while ago and it stopped working.
I installed clean windows10 for this arduino IDE earlier versions I only added STM32 and ibusBM. Unfortunately, no success.

Ok, I found a solution. The problem is the stm32duino ibus sensor works on the old version 1.9.0 on the newer one does not want to work in any way.
Is there a chance to solve this problem and where can I report it?
Is there a chance to adapt the library to the new version of stm32duino 2.2.0 ??
Thank you in advance for your help.

@bmellink This code work on version 1.9.0 but don't work on 2.0.0, 2.1.0, 2.2.0 (connect https://github.com/bmellink/IBusBM/raw/master/wiring.png?raw=true)
