Post by thread:I2C LCD question [OT]

Hi I have got a phillips branded 2x16 char LCD, model LTN211F-10 it came out a poker machine, and I picked it up cheap second hand. It has an OKI M5259 LCD driver and a OKI M6222B-01 chip on it. It has edge connectors for +,-,contrast,RW,RS,E,d0-d7. I am pretty sure that this LCD can support i2c protocol, BUT I don't know which pins to connect it to. Does anyone have a ref for the 6222B ? and the numbers of the I2C pins ? cheers

It is NOT a I2C interfeced Display. It's a parallel interfaced Display The datasheet is to found on the net. I dont have the URL but try to search for it with Altavista. -- // Jšrgen Tapani spam_OUTjorgen.tapaniTakeThisOuTnacka.mail.telia.com -----Ursprungligt meddelande----- FrŒn: Peter Gee <.....Peter.GeeKILLspam@spam@UTAS.EDU.AU> Till: PICLISTKILLspamMITVMA.MIT.EDU <.....PICLISTKILLspam.....MITVMA.MIT.EDU> Datum: den 7 december 1997 01:33 €mne: I2C LCD question [OT] >Hi >I have got a phillips branded 2x16 char LCD, model LTN211F-10 it came out a poker machine, and I picked it up cheap second hand. >It has an OKI M5259 LCD driver and a OKI M6222B-01 chip on it.

Peter, that sounds exactly like a standard Hitachi HD44780 compatible controller. This is a parallel interface using either 4 or 8 Bits. E is an Enable signal, RW is Read/Write, and RS is Register Select. You need to connect the wiper of a 10K pot to the Contrast line with the other two connections to + and - (+5V and Ground). - Tom At 11:31 AM 12/7/97 +1100, you wrote: >Hi >I have got a phillips branded 2x16 char LCD, model LTN211F-10 it came out a poker machine, and I picked it up cheap second hand. >It has an OKI M5259 LCD driver and a OKI M6222B-01 chip on it.

Or make a PWM to control the contrast, then it's all 'computerized' I have been thinking about making a lcd display i2c compatible with a pic, just for fun and to keep myself occupied with something.. And make the contrast/brightness (i've got some lcd's with backlight) controlable from the i2c.... - Thomas
