PIC32 and 3.2" QVGA LCD TFT with SSD1289 driver and 16 bits parallel bus

hi, could you tell me if you have to send images to lcd non stop or you just have to send it once and it stay's in the lcd?

@wytis Hi, sorry I'm French my english is not very good. Your answer is send it once and it stay's in the lcd. Look the SSD1289 datasheet, it's a LCD driver with one (active) frame memory. it's like a parallel memory + Horizontal, Vertical Lines and filled rectangular block primitive are accelerated + few basic options (vertical scrolling, window) No framebuffer i must draw and erase line by line in realtime.

@serveurperso thanks for the info

@wytis It would be a huge technical aberration wasting the precious PIC32 calculation time to refresh a LCD very slowly because a stupid dedicated chip (or a FPGA) can do it easily (and cheaply).

Je sais que je ne devrais pas écrire cela, mais le passage avec les Tux et les LOL me fait toujours mourir de rire.

@LunaVorax LOL lol bah si pourquoi pas écrire ça:D

@LunaVorax en plus ce LCD j'ai du le renvoyer au constructeur : données corrompues en mémoire on le vois légèrement sur la vidéo !
