Hi piclisters, I looked for VFD modules compatible with 44780 used for LCD. Peter Tiang answered kindly that samsung make compatible products. I went to their VFD website and I could'nt find any datasheet or any reference. I left message to sales department and webmaster without any answer. He gave me samsung's general website for europeen distributor but all of them (>10) sell only samsung semiconductors and no ones know that samsung make VFDs. Grrrr ! I'm a little tired with this compagny : (my english is only technical but I have others words in my langage to say what I think really). Any informations are welcome.
