I am trying to run two I2C busses on a Nano32.
#include <Wire.h>
#include "MS5837.h"
// Setup sensor 1
#define I2C_SDA_1_PIN 21
#define I2C_SCL_1_PIN 22
TwoWire I2C_1 = TwoWire(0);
MS5837 sensor_1;
// Setup sensor 2
#define I2C_SDA_2_PIN 17
#define I2C_SCL_2_PIN 16
TwoWire I2C_2 = TwoWire(1);
MS5837 sensor_2;
void setup() {
Serial.begin(115200);
Serial.println("Starting");
I2C_1.begin(I2C_SDA_1_PIN, I2C_SCL_1_PIN);
I2C_2.begin(I2C_SDA_2_PIN, I2C_SCL_2_PIN);
while (!sensor_1.init(I2C_1)) {
Serial.println("Init sensor 1 failed!");
delay(5000);
}
while (!sensor_2.init(I2C_2)) {
Serial.println("Init sensor 2 failed!");
delay(5000);
}
}
void loop() {
}
The MS5837 library comes from https://github.com/bluerobotics/BlueRobotics_MS5837_Library and is not the one that can be installed via the Arduino IDE. The reason for that is that that version does not allow the setting of the TwoWire port to use.
The issue I am facing is that I get the following error message when compiling:

Sketch uses 273661 bytes (20%) of program storage space. Maximum is 1310720 bytes.
Global variables use 22672 bytes (6%) of dynamic memory, leaving 305008 bytes for local variables. Maximum is 327680 bytes.
I am at a loss as to how to fix this and would appreciate pointers.

Here is the part of the code we are getting the error on

int measure = analogRead(A0);

measureMap = map(measure, 0, 1023, 0, 63);

Where we have the variable measureawe get an error saying
measurea

How to fix the error?
The problem is that you already declared measurea and measure as a define macro.
You can't make a variable with the same name.
try this:
//turns on the i2c commands
#include <Wire.h>
//creates a variable called SLAVE_ADDRESS and permanently sets the value to 0x04 (register #4)
#define SLAVE_ADDRESS 0x04
#define IR1 A0
#define IR2 A1
void setup()
{
Serial.begin(9600);
//sets the address of the Arduino
Wire.begin(SLAVE_ADDRESS);
//the .onRequest command will run a function when it gets a request from the EV3.
//In this case, it will run the requestEvent function, which is defined later in the sketch.
Wire.onRequest(requestEvent);
}
int measureMap = 0;
void loop() {
int measure = analogRead(A0);
int measurea = analogRead(A1);
measureMap = map(measure, 0, 1023, 0, 63);
Serial.print(mapMeasure);
Serial.print (" ");
Serail.println(measure);
Serail.println(measure1);
}

Blynk uses an open source SimpleTimer library.
There are quite a few libraries called SimpleTimer out there - See GitHub Search Results.
If you have a different version of the library to that used by Blynk you'll probably get a compile error:
BlynkTimer.h: 36:21: error: redefinition of 'class BlynkTimer
If you use the library that Blynk uses - marcelloromani/Arduino-SimpleTimer - you will not get errors on build, and can #include <SimpleTimer.h> and use it alongside Blynk without problem.
If you are using Blynk it is advisable to use BynkTimer instead of `SimpleTimer' for the following reason:
When BlynkTimer struggles to run multiple times (due to a blocked loop), it just skips all the missed intervals, and calls your function only once. New Blynk Library Release v0.5.3 - June 2018
To make the change to your code, remove
#include <SimpleTimer.h>
and replace
SimpleTimer timer;
with
BlynkTimer timer;
Ive got a ESP32-S2 and just try to test the circuit and the Board with this simple script.

If you use #define addr1 0 the compiler can't choose between begin(pointer) and begin(int), because the value from #define could be a pointer.
If you set the I2C address as typed constant of type uint8_t, which is the type of the address parameter in the begin function with I2C address, the compiler will use the right function.
So set the addresses this way const uin8_t addr1 = 0;
Basically, the Adafruit_MCP23017 library is bad. You may need to edit the library. There are actually two begin functions that you could potentially be calling, and Arduino has no idea which one you want.
Option 1:
You could add the following line outside of setup():
#define Wire TinyWireM
and changing your begin functions to:
mcp1.begin(addr1, &Wire);
mcp2.begin(addr2, &Wire);
mcp3.begin(addr3, &Wire);
mcp4.begin(addr4, &Wire);
mcp5.begin(addr5, &Wire);
mcp6.begin(addr6, &Wire);
mcp7.begin(addr7, &Wire);
mcp8.begin(addr8, &Wire);
Option 2:
Currently, the two begin functions in the library look like this:
void begin(uint8_t addr, TwoWire *theWire = &Wire);
void begin(TwoWire *theWire = &Wire);
My recommendation above is based on the assumption that you are using the first function.
Your second option would be to remove the second function.
Remove the following from Adafruit_MCP23017.cpp (starting form line 133):
/**
* Initializes the default MCP23017, with 000 for the configurable part of the
* address
* #param theWire the I2C object to use, defaults to &Wire
*/
void Adafruit_MCP23017::begin(TwoWire *theWire) { begin(0, theWire); }
Remove the following from Adafruit_MCP23017.h (line 27):
void begin(TwoWire *theWire = &Wire);
I can further guide you in editing the library if needed

The error message is telling you that the signature of the callback function you are passing to the constructor is incorrect.
You have:
void callback(char topic, byte payload, unsigned int length){
It should be:
void callback(char* topic, byte* payload, unsigned int length) {
Note the * for the topic and payload arguments.
