Begginers help needed for i++

Projects Programming
1

I'm making a HID joystick, (actually a DJ controller but the code is for a joystick) My problem is my HEX file to make the arduino HID is 22KB so it is too big.

In my source files, usb_gamepad.c, I have some long lists that I think I could shorten with a i++ operation

Being a noob, I'm not sure how to do it

Below is my code and ............... represents missing numbers.
Could someone help me out please.

// zero when we are not configured, non-zero when enumerated
static volatile uint8_t usb_configuration = 0;

static const gamepad_state_t PROGMEM gamepad_idle_state = {
	.b0_btn = 0, .b1_btn = 0, .b2_btn = 0, .b3_btn = 0,
	.......................        .b126_btn = 0, .b127_btn = 0,	
	
	.a0_axis = 0x80, .a1_axis = 0x80, .a2_axis = 0x80, .a3_axis = 0x80,
	...........................                    .a46_axis = 0x80, .a47_axis = 0x80,


	.b0_axis = 0x00, .b1_axis = 0x00, .b2_axis = 0x00, .b3_axis = 0x00,
	..................                          .b126_axis = 0x00, .b127_axis = 0x00
};

There's also this bit where I think the implementation would be slightly different

int8_t sendPS3Data(dataForController_t btnList){
	
	gamepad_state.b0_axis = btnList.bt0On;
	gamepad_state.b1_btn = btnList.bt1On;
	gamepad_state.b2_btn = btnList.bt2On;
        ....................
	gamepad_state.b127_btn = btnList.bt127On;
	
		
	
	if (gamepad_state.b0_btn == 1)
	gamepad_state.b0_axis = 0x01;
	else
	gamepad_state.b0_axis = 0;
	
	if (gamepad_state.b1_btn == 1)
	gamepad_state.b1_axis = 0x01;
	else
	gamepad_state.b1_axis = 0;

	if (gamepad_state.b2_btn == 1)
	gamepad_state.b2_axis = 0x01;
	else
	gamepad_state.b2_axis = 0;
	
        .....................................

	if (gamepad_state.b127_btn == 1)
	gamepad_state.b127_axis = 0x01;
	else
	gamepad_state.b127_axis = 0;
	

	// left and right analog sticks, 0x00 left/up, 0x80 middle, 0xff right/down

	gamepad_state.a0_axis = btnList.al0;
	gamepad_state.a1_axis = btnList.al1;
	gamepad_state.a2_axis = btnList.al2;
        ..........................
	gamepad_state.a47_axis = btnList.al47;
	
	
	// Send the data out via USB
	return usb_gamepad_send();
}

Thanks for reading.

An array instead of all those bxxx_btn fields...

Thank you, could you please give me an example, I assume I could do the same with axxx_axis and bxxx_axis too?

void setup() {

  for (int thisPin = 0; thisPin < pinCount; thisPin++)  {
    pinMode(ledPins[thisPin], OUTPUT);      
  }
}

I understand what is happening here , in the learning example but I don't understand how it would be done for my instance.
I get that it would be < 127.
