Hardware serial

[PartyLime99]

Hi,

Sorry if this is the wrong place to post this. I'm struggling to find a good place to ask my question.

Your library has been great while trying to set up a laser gate timing system. I have 2 Arduino Nanos sending and an Uno receiving. I am now onto adding a screen to my setup and have switched to an Adafruit Metro M0 rather than the Uno. The M0 does not allow a software serial.

You mention in your description "Some MCU such as the Teensy, and ESP32 do NOT allow the use of SoftwareSerial to create a communications port. No worries, just hard wire the EBTYE to a dedicated UART port (pin 0 and pin 1 on a teensy 3.2 for Serial1." however, I am very new to programming and can't figure out how to set this up. What do I replace SoftwareSerial loraSerial (2,3); //TX, RX with? I have tried replacing SoftwareSerial with Serial1 but it says "Serial1 does not name a type".

I have my basic code below which works as a receiver on the uno

Thanks in advance, Ben

#include <SoftwareSerial.h>
#include "EBYTE.h"

//If using direct wiring, use these pin definitions
//#define PIN_M0 4 
//#define PIN_M1 5 
//#define PIN_AX 6

SoftwareSerial loraSerial (2,3); //TX, RX
EBYTE Transceiver(&loraSerial); //PIN_M0, PIN_M1, PIN_AX);

void setup() {

  Serial.begin(9600);
  loraSerial.begin(9600);
  Transceiver.init();
  Transceiver.SetMode(MODE_NORMAL);
  Transceiver.SetAirDataRate(ADR_9600);
  Transceiver.SetTransmitPower(OPT_TP17);

}

void loop() {

   if (loraSerial.available()>0){
    String input = loraSerial.readString();
    Serial.print("I received: "); Serial.println(input);
   }

}

From what I see that unit has only 1 hardware serial port Pin0=Rx and Pin1=Tx, This means you will have to connect the EBYTE Rx to pin1 and EBYTE Tx to pin0--however you will not be able to program the unit when these pins are connected to the EBYTE.  // SoftwareSerial loraSerial (2,3); //TX, RX EBYTE Transceiver(Serial); //PIN_M0, PIN_M1, PIN_AX);

Basically  unconnect the EBYTE, program the unit and connect the EBYTE back up--you can't use Serial monitor when EBYTE is connected, so debugging is a pain.

I have a similar situation and i put jumpers on my PCB board for "program" and "run"

Thank you so much for the fast reply!

So I have done as you say and I get the following error while compiling:

Arduino: 1.8.13 (Windows 10), Board: "Adafruit Metro M0 Express, Small (-Os) (standard), Arduino, Off"

This report would have more information with

option enabled in File -> Preferences.

I see how the no serial for debugging will be a nightmare. Hopefully the simplicity of the project will help. Maybe I can debug by writing on the screen attached to it.

you must pass in the other arguments for the following line...not sure why I commented it out in my first reply... ChangeEBYTE Transceiver(Serial); //PIN_M0, PIN_M1, PIN_AX); to EBYTE Transceiver(Serial, PIN_M0, PIN_M1, PIN_AX); Sorry....

I'm still getting a similar error:

I think instead I will use a nano with the ebyte module to recieve the message and set up I2C between the that and the Metro M0 to forward it on. I think this should simplify things for me and work for what I need.

you need to pass in Serial and NOT ESerial. EBYTE Transceiver(Serial, PIN_M0, PIN_M1, PIN_AX);

Sorry, needs an ampersand. EBYTE Transceiver(&Serial); //PIN_M0, PIN_M1, PIN_AX);
