how? 2 wire lcd with pbp?

[nimonia]

is it possible to use shiftout with 2 wire lcd configuration? or do we have to shift the datas and strobe the data and clock pins manually

i'm not sure of your of your actual LCD but more than often they use simple serial communication @2400/4800/9600 bauds. Use Hserout or Serout statement.

P.S.: for all your future post, please include more details.. part #, web link, provider or any info you have. That help us to give you the right answer.

HI,

Another solution is using an I2C device like the PCF 8574 ...that allows bus sharing.

I think the questions are:

Can I redirect the output of the PicBasic LCDOUT command to my 2-Wire LCD Interface?
(I am using an LCD module with a Hitachi 44780 controller or equivalent).

Would I have to write my own LCD routines in order to use my 2-Wire LCD Interface?

I do recall posting this a couple of years back... you will have to use SHIFTOUT or similar commands to drive it.
