Store code somewhere and call it when needed

Hello,

I'm working on a custom A.I using a Movi Shield. I'm adding a lot of commands and although I haven't yet run out of storage/memory space on my Arduino Mega, I'm wondering if I could store portions of my A.I's code on another Arduino Mega so I don't have to worry about running out of room any time soon.

For example, I can ask my A.I to tell me a joke, and it will choose from a list of jokes.

//Jokes
  void Jokes(){
  char *jokes[]={
  "I'm afraid for the calendar. It's days are numbered",
  "My wife said I should do lunges to stay in shape. That would be a big step forward",
  "Why do fathers take an extra pair of socks when they go golfing? In case they get a hole in one",  
  "Singing in the shower is fun until you get soap in your mouth. Then it's a soap opera",  
  "I only know 25 letters of the alphabet. I don't know y", 
  "What does a sprinter eat before a race? Nothing, they fast"
    };
  long jokes1;
    jokes1 = random(sizeof(jokes)/sizeof(char*)); //Randomly says a joke
    recognizer.say((jokes[jokes1])); //Say joke 
    RGB_color(255, 255, 255); //White
   //Display then turn off after 4 sec
   time_now=millis();
   while(millis()<time_now+period4){
   //wait approx 4sec
   }
  RGB_color(0, 0, 0); //Off
  }

The problem is, the more jokes I add, the more space I use. I want to add more jokes but I want to store them somewhere else and call them when needed. I would like to do this for most of my subroutines and my A.I's responses.

I already have both of my Arduino Mega's hooked up to each other, and I'm wondering how to "offload" some of my main code to my second Mega to save room.

So I'm wondering how to do this, if this will save me storage & memory space, and if the code will still run well?

Thanks in advance.

Here is my A.I's code so far:

#include <LiquidCrystal.h>
#include <Wire.h>
#include <Adafruit_SSD1306.h>
#include <Adafruit_GFX.h>
#include "MOVIShield.h" // Include MOVI library, needs to be *before* the next #include

#if defined(ARDUINO_ARCH_AVR) || defined(ARDUINO_ARCH_PIC32)
#include <SoftwareSerial.h> // This is nice and flexible but only supported on AVR and PIC32 architecture, other boards need to use Serial 
#endif


MOVI recognizer(true); // Get a MOVI object, true enables serial monitor interface, rx and tx can be passed as parameters for alternate communication pins on AVR architecture

//MOVI Uses Pins 10 & 11 to Communicate With the Arduino. To rewire MOVI’s communication to different pins, open Jumper 2 and Jumper 3 and connect the right side of MOVI's TX jumper (Jumper 2) 
//and the right side of MOVI's RX jumper (Jumper 3) to two other connectors on the Arduino headers using jumper wires. The right side is the pin that is closer to the power and USB plugs.

//PINS 10 & 11 ARE OFF LIMITS. DO NOT CONNECT ANYTHING TO THEM OR THE MOVI WON'T RESPOND OR EXECUTE ANY COMMANDS.

I have, in the past, used the EEPROM in a RTC so store a lookup table.

Since I have been using ESP32's, memory has not been an issue.

have you considered storing strings in PROGMEM?

Storing code other than in the program memory would be troublesome.

However, storing strings like your "jokes" is relatively easy:

  1. They could be stored in flash, freeing RAM (RAM is much smaller than flash on most microcontrollers.)
  2. They could be stored on an external EEPROM, FRAM, or Serial Flash chip. There are already libraries that will make this relatively easy. Small chips holding up to about 16MB of data are relatively cheap.
  3. They could be stored on something like an SD card. I'm not sure of the status of the existing libraries WRT today's "typical" 16-32GB SD card size, but you can usually find older cards in the 64M-2GB range that should work fine.

(larger external storage schemes tend to use a "filesystem" to keep the space organized. Just like your PC.)

How would I go about programming that and what's the hardware called that I would need?

I recommend an SD card also, store all you want there, SD cards are 4/8/16/32 Gigabyte, vs the minuscule (in comparison) 256 Megabyte (1/4 Gigabyte) in the Mega2560.

Ok. So I would use something like this, correct?

Yes.
There is no active 5V to 3.3V level conversion, and 3.3V to 5V.
There are just resistors in series with the control signals. See sheet 62 of the datasheet

If you have trouble with SD cards, then look for another adapter that has signal level conversion chips on them.

Ok, thanks.

I can hear your AI code screaming "Put me in a function!!!"
