Tópico: Maschine MK3 screens
Hi there,
A friend of mine want to be able to use Maschine MK3 screens plus pads for some gigs.
I am trying to dig into it, will someone help me to put that in order ?
Been capturing USB packets between NI Maschine 2 & Maschine MK3.
Found this :

Résolution : 480×272 pixels (by screen)
Pixel : RGB565 (16-bit per pixel)
Taille de frame : 480 × 272 × 2 = 261,120 bytes by screen

USB Interface
Data :
Interface #5 : Vendor-specific (Class 0xFF)
Endpoint : Bulk OUT (0x04)
Type de transfert : USB Bulk Transfer

Séquence :
├─ Paquet 1 : 107 bytes (Header 1)
├─ Paquet 2 : 107 bytes (Header 2)
├─ Paquet 3 : 491 bytes (Pixels data)
└─ Paquet 4 : 875 bytes (Pixels data - often empty)

Header
struct DisplayHeader {
uint32_t magic; // 0x2A080008 (magic number)
uint32_t reserved1; // 0x00000000
uint32_t reserved2; // 0x00000000
// ... métadonnées de position/région
// 95 bytes de données additionnelles
};

Pixels data

Total sequence : 491 + 875 = 1,366 bytes
coded pixels : 1,366 / 2 = 683 pixels en RGB565
sequences for 1 frame : ~191 sequences

Is this enough to do a plugin and what will be the process ?
create plugin, Initialise USB, send frame, convert rgb ?
@djdad ?
Thank you,
