Another way is to control the LCD's VCC with the PIC, then the state
you start from is always the power up state.

Since these Hitachi chips are notorious for getting garbled by ESD,
etc, this might be a good idea.

Subject: 24LC08 & LCD reset


Hi all,

A couple of questions:

Does anyone have some bare bones read write routines to interface a PIC
16F84 and one or two 24LC08 's?

and:

I have an LCD display with the Hitachi chip set hooked up in 4 bit mode.
Works fine.

But, when the processor resets and resend the software start-up sequence to
the LCD, the LCD goes south.

This works fine on power-up. I have corrected the problem by causing a push
of the reset button to also power down the LCD.

What's the trick to getting a software init to work on the LCD?

TIA
Mac
