Hello There is an interesting web site to check : http://www.paranoia.com/~filipg/HTML/LINK/F_Tech_LCD.html I hope it will be helpful for you. -----Original Message----- From: Eric Martens [SMTP:emar@KNOWARE.NL] Sent: Thursday, May 29, 1997 4:31 AM To: PICLIST@MITVMA.MIT.EDU Subject: PIC & LCD Hello Guys I have a little problem, it is not the normal stuff for this mailing list so i'll try to keep it as short as possible I have two very nice LCD's in my possession, one 2 x 32 characters and one 4 x 32 characters. I'm designing an audio control center and i want to use one of these two LCD's. Preferable the 4 x 32 characters. I'm using a PIC 16C62 to control the audio center. I'm first my gathering al the datasheets of the components i'm using. But i don't have the datasheets of the LCD's. I can't remember where i got the LCD's from and there is no manufactures name on them. On the back of the 4 x 32 LCD there are two numbers: M3214 and F1632 separated by a slash (/). I don't now if this rings a bell with any of you ??? The only thing i know for sure is that both the LCD's use the same controller or better said controllers. the 4 x 32 has 8 of them and the 2 x 32 has 4 of them. The Controller i'm talking about is the D7227G from NEC in Japan. From the number of controllers on the LCD's and the shape of the characters i conclude that it is a 16 character controller consisting of 16 x 5 kolom drivers and 8 row drivers (7 for the characters and one to underline the characters). Does anyone reconize these LCD's ? Do you know the processor ? I'm interested in character tables, datasheets, end so on. Any help would be much appriciated. I have tried it with NEC in Japan but like all other japanese manufactures they don't reply to your questions if your not a bulk user. I hope someone can help me otherwise i'll be forced to buy new LCD's and in that size there not cheap !!!!
