So with this modification what do you control, what kind of mechanics?
Question, do you think it is possible to adapt an SPI display with your PCB?

These are the pins I would like to adapt to control Philips CDM mechanics:
#include <DSA.h> // Include the custom DSA library for communication with CD-Pro2M/LF
#include <Wire.h> // Required for I2C communication (even if OLED here uses SPI, sometimes it's a dependency)
#include <SPI.h> // Required for SPI communication with the OLED display
#include <Adafruit_GFX.h> // Adafruit's basic graphics library
#include <Adafruit_SSD1306.h> // Specific library for the SSD1306 OLED display
#include <IRremote.h> // Library for the IR receiver
#include <math.h> // Required for sin() function for vumeter animation
// --- Hardware Definitions ---
#define SCREEN_WIDTH 128 // OLED display width in pixels
#define SCREEN_HEIGHT 64 // OLED display height in pixels
// Pin di connessione per il display OLED (SPI)
// Questi pin devono corrispondere ai collegamenti fisici sul tuo Arduino.
// Per Arduino UNO/Mega: MOSI (51/11), MISO (50/12), SCK (52/13) sono gestiti automaticamente dalla libreria SPI.
#define OLED_DC 8 // Data/Command (D/C) Pin
#define OLED_CS 53 // Chip Select (CS) Pin
#define OLED_RESET 9 // Reset (RES) Pin
#define IR_RECEIVE_PIN 2 // Pin to which the IR sensor is connected (e.g., Arduino D2 Pin)
// Create a DSA controller instance, defining pins in "Data", "Strobe", and "Acknowledge" order
// Ensure pins (25, 26, 27) match your physical connections for DSA communication.
DSA myDSA(25, 26, 27);

2. It is possible, but you must control time for data transfer to display. I think about 2-5milliseconds.
Display Buffer Size:
A 128x64 pixel SSD1306 display has a memory buffer of 128 * 64 / 8 = 1024 bytes. Each byte controls 8 pixels vertically.
When you call display.display(), the entire image (1024 bytes) is transferred to the display.
Theoretical Transfer Time Calculation:
Data Rate: 4 Mbps (megabits per second) = 4,000,000 bits/second.
Bytes per second: 4,000,000 / 8 = 500,000 bytes/second.
Time to transfer 1024 bytes: 1024 bytes / 500,000 bytes/second = 0.002048 seconds = 2.048 milliseconds.

The tests I did with the CDM philips mechanics and arduino were done with an Atmega2560, my idea is to use an Atmega1248P from what I saw the pinout between mega32 and mega1284 is identical, so I assume that by checking the pins well I can adapt your controller which I would replace with mega1284.
I could try to convert the file and adapt it by changing the pins or adding new connectors for the CDM servo control.

Even though I would have already created the PCB with the possibility of being programmed directly from the PCB.
