Pro trinket EEPROM read and write - arduino

Question

(I am using Arduino IDE)
The Thing I am trying to achieve is it saving the "progress" even when the microcontroller turns off. I have tried for a while tweaking the code but I have yet to get it to actually save/read values from EEPROM properly, so here's the part of my code(Ignore the rest for running the display+i have removed all of the irrelevant code):
#include <EEPROM.h>
int hunger = 10000;
int happiness = 10000;
int y = 0;
int z = 0;
int sensorPin = A0;
int sensorPin2 = A1;
void setup() {
Serial.begin(9600);
EEPROM.write(5, 10000);
EEPROM.write(5, 10000);
hunger = EEPROM.read(8)- '0';
happiness = EEPROM.read(5)- '0';
display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
display.display();
display.clearDisplay();
display.display();
Serial.begin(9600);
pinMode(sensorPin,INPUT);
}
void loop() {
int value = happiness;
int value2 = hunger;
EEPROM.write(5, happiness);
EEPROM.write(8, hunger);
hunger -= 1;
happiness -= 1;
if(analogRead(sensorPin)>1020){
testhappy();
happiness+=2500;
}
else{
testsad();
}
while(analogRead(sensorPin2)>1020){
testeat();
hunger+=5000;
}
}
void testhappy(void){
display.setTextSize(2);
display.setTextColor(WHITE);
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap(30, 32, Happy32_glcd_bmp, 32, 32, 1);
display.display();
delay(1);
display.display();
delay(1);
for(y=0;y<2;y++){
for(z=0;z<5;z++){
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap((30+z), 32, Happy32_glcd_bmp, 32, 32, 1);
display.display();
}
for(z=5;z!=0;z-=1){
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap((30+z), 32, Happy32_glcd_bmp, 32, 32, 1);
display.display();
}
for(z=0;z> -5;z-=1){
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap((30+z), 32, Happy32_glcd_bmp, 32, 32, 1);
display.display();
}
for(z=0-5;z!=0;z+=1){
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap((30+z), 32, Happy32_glcd_bmp, 32, 32, 1);
display.display();
}
}
display.stopscroll();
}
void testsad(void){
display.setTextSize(2);
display.setTextColor(WHITE);
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap(30, 32, Mild32_glcd_bmp, 32, 32, 1);
display.display();
delay(1);
}
void testeat(void){
delay(200);
for(y=0;y<6;y++){
display.setTextSize(2);
display.setTextColor(WHITE);
display.setCursor(0,0);
display.clearDisplay();
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap(30, 32, Eat32_glcd_bmp, 32, 32, 1);
display.drawBitmap(60, 38, Cookie18_glcd_bmp, 8, 8, 1);
display.display();
delay(200);
display.clearDisplay();
display.setCursor(0,0);
display.print(hunger/100);display.print("/");display.print(happiness/100);
display.drawBitmap(60, 38, Cookie28_glcd_bmp, 8, 8, 1);
display.drawBitmap(30, 32, Mild32_glcd_bmp, 32, 32, 1);
display.display();
delay(200);
}
}
void testdrawbitmap(const uint8_t *bitmap, uint8_t w, uint8_t h) {
uint8_t icons[NUMFLAKES][3];
// initialize
for (uint8_t f=0; f< NUMFLAKES; f++) {
icons[f][XPOS] = random(display.width());
icons[f][YPOS] = 0;
icons[f][DELTAY] = random(5) + 1;
Serial.print("x: ");
Serial.print(icons[f][XPOS], DEC);
Serial.print(" y: ");
Serial.print(icons[f][YPOS], DEC);
Serial.print(" dy: ");
Serial.print(icons[f][DELTAY], DEC);
}
while (1) {
// draw each icon
for (uint8_t f=0; f< NUMFLAKES; f++) {
display.drawBitmap(icons[f][XPOS], icons[f][YPOS], bitmap, w, h, WHITE);
}
display.display();
delay(200);
// then erase it + move it
for (uint8_t f=0; f< NUMFLAKES; f++) {
display.drawBitmap(icons[f][XPOS], icons[f][YPOS], bitmap, w, h, BLACK);
// move it
icons[f][YPOS] += icons[f][DELTAY];
// if its gone, reinit
if (icons[f][YPOS] > display.height()) {
icons[f][XPOS] = random(display.width());
icons[f][YPOS] = 0;
icons[f][DELTAY] = random(5) + 1;
}
}
}
}
(I am getting no errors when compiling the code)

Answer 1

Look here at the page for EEPROM.write here. https://www.arduino.cc/en/Reference/EEPROMWrite
There it says the arguments are defined as:
EEPROM.write(address, value)
Parameters address: the location to write to, starting from 0 (int)
value: the value to write, from 0 to 255 (byte)
Now look at the number you're trying to write into EEPROM:
EEPROM.write(5, 10000);
Hopefully now you can see what the problem is. Your second argument is far too large. You should break it into two bytes or use a different method like EEPROM.put (look that up) which doesn't suffer this limitation.
