Trouble with an Arduino Mega

[flightblog]

I'm not having any luck with an Arduino Mega and the sample code. I'm using an inverter that has worked with an MKR1010 and I'm have RX pinned to 17 (RX2).

#include "sbus.h"

/* SBUS object, reading SBUS */
bfs::SbusRx sbus_rx(&Serial2);
/* SBUS object, writing SBUS */
bfs::SbusTx sbus_tx(&Serial2);
/* SBUS data */
bfs::SbusData data;

void setup() {
  /* Serial to display data */
  Serial.begin(115200);
  while (!Serial) {}

  delay(2000);

  /* Begin the SBUS communication */
  Serial.println("Begin SBUS...");
  sbus_rx.Begin();
  sbus_tx.Begin();
}

void loop() {

  if (sbus_rx.Read()) {
    /* Grab the received data */
    data = sbus_rx.data();
    /* Display the received data */
    for (int8_t i = 0; i < data.NUM_CH; i++) {
      Serial.print(data.ch[i]);
      Serial.print("\t");
    }

    /* Display lost frames and failsafe data */
    Serial.print(data.lost_frame);
    Serial.print("\t");
    Serial.println(data.failsafe);
    /* Set the SBUS TX data to the received data */
    sbus_tx.data(data);
    /* Write the data to the servos */
    sbus_tx.Write();
  }
}

Occasionally I will receive data from sbus_rx.Read()

Hard to say, even the posted data looks kind of garbage. I'll have to dig around to see if I have a Mega to test with.

The Arduino Mega does not support baudrate of 100000, better change to a 32bit microcontroller
