L'atelier [RESOLU] OPL3 Conception d'un périphérique OPL3
@TheWhipMaster: Effectivement, je vois que la DRAM qui contient l'ADPCM est reliée directement sur l'Y8950.
Donc à moins que l'OPL3 émule précisément l'ADPM de l'OPL1, je pourrai pas implémenter cette mémoire

Tu peux toujours ajoute un SCC et jouer les PCM avec http://d4.princess.ne.jp/download/lzhdown.cgi?scc4b
HB-F700F(X2),A1GT,Altera DE1 + slots , Sunrise IDE CF,FMPAC, Music Module,Slot expander 8X (X3) ,PlaySoniq, et autres
Igal, pourrais tu reposter ton schemas , celui avec plein de couleur 
stp, la plus simple et en version HD 
Merci

L'implantation:
Le schéma:
ATTENTION: Le schéma prévoit une SRAM 6116 en UC. J'ai remplacé cette SRAM par une SRAM CK58256 sur le dessin d'implantation.
ATTENTION2: Le schéma est buggé sur /IORQ. il faut inverser la Pin 8 et la Pin 9 Edité par igal Le 09/09/2013 à 00h32

L'implantation je l'ai mais tu ne l'a pas de meilleur qualité ?
Sinon ça devrais aller merci

Le 7805 chauffe beaucoup dans ton montage.
Met 1 resistance 100 ou 120 Ohm 1/2w sur le +12 du 7805
Met 1 condo polarisé 1uF 25V sur le +12 et GND
Met 1 condo polarisé 1uF 25v sur le +5v et GND
les 2 condo ont le - vers la masse bien entendu.
ça fonctionne tres bien, ça ne chauffe presque plus
Voila, je te suis des que j'ai finalisé ma combi "flash rom SCC/FM" Edité par MSXlegend Le 09/09/2013 à 16h07

Après quelques échanges avec I_Oliveira, ce dernier nous offre son schéma perso de l'OPL3.
Au passage il me signal qu'il n'y a pas d'erreur sur IORQ et qu'il doit bien être câblé comme présenté sur le schéma de départ.
Plus d'infos par ici => http://www.msx.org/forum/msx-talk/software/vgmplay-msx?page=6
Voici son nouveau schéma:
A la sienne
J'ai essayé de gratter son schéma OPN, mais bon... Bientôt peut être

Bonjour. Quelle différence avec la FM classic?
J'aimerais me faire une collection de carte son, je pourrais en faire un pcb si ça en vaut le coup

@ l_oliveira: merci pour ces précisions
@msxlegend: il me semble qu'à partir de L'OPL2, les mélodies sont en stéréo.
Donc les mélodies opll (fmpac) seront jouées en stéréo véritable
D'autre part, à chaque nouvelle génération, les modulations de fréquences au travers des moulinette "operateurs" etc fait que mélodie fm composée pour un opll sera bcp plus belle sur opl3/4 que sur la fmpac. (attend un peu et l_oliveira va partager son schéma OPN2 )

J'ai plus ou moins compris Igal 
Est ce compatible avec les jeux FM?

Famille OPM est le synthétiseur original pour ordinateur personnel. Produit haut de gamme.
Famille OPN était simplification des OPM produit avec ajout de SSG (YM2149) capacité. Aussi Yamaha ajouté enveloppes SSG à EG (générateur d'enveloppe) à OPN partie FM de la famille. Cette caractéristique SSG EG est unique à la famille OPN.
Famille OPL sont simplifiées synthétiseurs FM où objectif était moindre coût:
OPL(YM3526) = MONAURAL
OPL2 (YM3812) = OPL (OPL2 a formes d'onde supplémentaires dans l'opérateur de FM)
OPL3 = STEREO (OPL3 est capable de 16 formes d'onde et 4 algorithme de l'opérateur. Activation 4OP réduit le nombre de canaux de sortie possibles)
OPL4 = STEREO (OPL4 identique à OPL3 mais OPL4 a table d'onde synthétiseur ajoutée) Edité par l_oliveira Le 22/03/2015 à 15h07
