Driving Varitronix VI-302 lcd using PIC microcontroller

[adnan012]

hi,

I want to drive VI-302 ststic lcd using any pic controller.

Is there any internal contoller in this LCD?

How can i program it.

Hi,

No, there is no controller on that display module.

If you look on Microchips site you will find there are some Pic chips with built in LCD drivers designed to directly drive such lcds, but have not used them myself.
Also search their site / app notes for suitable software.

Assume you are wanting to use it because of the large digits that a conventional 2x16 lcd does not have.

You could use a glcd with large fonts to give the same effect, they typically run on the spi bus.

i want to use ultra low power lcd.

How can i program this LCD.

There is a code

is there any one who can anyone explain it.

The site you refer to is reported as containing malware.

Anyway, just google for static LCD driver. As wp100 mentioned, some microcontrollers have built-in drivers for LCDs, otherwise
you could try to generate the waveform yourself, e.g. **broken link removed**.

Hi,

That software is for the smd TI boards.

For a Pic driven system you have to us the Pic18 or Pic24 lcd segment driver smd chips.
A demo board with software is found here.

You could use the method shown by sky_123 but your 3 1/2 digit display would probably still require a 64+ pin smd chip assuming your circuit also has other i/o functions.
