LCD graphics modules are not always easy to drive. Sometimes you have an embedded processor system X, and writing yet an other driver for the LCD module may suck. It may also suck if the LCD display has to be far away from the PC, say several meters. To solve that, I programmed a Microchip PIC 18F14K22 as graphics controller for a 128x64 HG1286418C graphics LCD module. It is controlled vi...

Are these made? If not, available surplus? Package size cannot be changed and will not take typical LCD's of 2 x 16/20 (or larger). Don't want graphic lcd if possible - too much uC oomph and coding needed, I think.

I'm using a 320x240 monochrome LCD with a built-in high voltage generator. As is probably standard, the LCD bias is provided out of the module, and I have to use a resistive divider to provide this voltage back into the module for contrast adjustment. This simple two- resistor circuit is given in the datasheet. The LCD contains a controller if that helps (RA8835). Up until now, I've alw...

I have a passive LCD with 8 7-seg digits plus point and some other symbol. It has 23 connections. I wish to drive it with a PIC that has LCD module built-in but I have seen that all PICs capable to drive LCD have only 4 commons. I supposed that was needed 1 common for each digit but probably I have to use bias plus multiplex. In this case how can I do? I have not found any application notes ...

I've got a "Nokia 1100" LCD, which (unless I be mistaken) is based on PCF8814, whose digital I/O range is (1.7 .. 3.3) V. The question is: is there an easy and safe way to connect it to an otherwise 3.3 V (+/- some) circuit (as in: one interfacing an SD card, or having an Arduino as its core, etc.)? (Will a few diodes suffice, for instance?) Also, the pinout for the LCD (e. g., ...

After trying Google, McMaster, and lots of others: Is there a see-through (thin) mesh that can be fastened to the back of a steel panel using conductive epoxy around the perimeter? Preferably something that can't rust. It is to protect a LCD from getting hit by strong fields or really big ESD zaps. Currently there is only some kind of poly film 1/10th" away from the LCD (doesn't touch...
