Numeric lcd display driver

Im designing a thermometer with dual sensor, i display the temperature in 7 segments LEDS displays now, the thermometer will use battery, i should use LCD display but, it will be mount in vehicles, trucks, trailers, so they will need to check temperature different times in day, it include nights that could be harder to read an LCD.

You can use an adapter socket with your regular programmer but the extra handling involved in programming may bend the pins on an SMD package.

All PIC's except 16C5x series program this way. You can easily build a programming adapter cable from Picstart Plus to connect with a 4 or 5 pin header on your board. Hi Gerardo, The 16C5x family use a parallel programming method which connects to around 16 or 17 pins on the package for so any form of ICSP with this family is out of the question. Ironwood Electronics www. My feeling is that Microchip ought to start marking the 16C5x family as "Not recommended for new designs", they are very old technology and something of a nuisance when you want to upgrade to the more up-to-date members of the PIC family hope I have not offended ardent fans of the 16C5x!

The bit core processors are very simple. Thus very, very reliable. If I were horking in high energy ionizing radiation environment, bit PIC is the first choice from worlds production of processors. And no. No marking the bit as obsolete. We need to have sonething in wristwatches, right?

Hi Friends, Logging in after a long time LCDs also have multiple backplanes, and so require staircase waveforms at 3V or so for driving.

Dedicated drivers are available from Holtek, Philips etc. Best Regards, Jayant. This glass runs in multiplex drive mode driven only by the pic16C74A. Believe me it's not easy. I utilize no other support chip.

The pic generate all timing and 3 DC level control to drive the glass. Login or Sign Up 0. Our staff understands the necessity of quick, knowledgeable engineering support. Like our journals?

The library only works with parallel displays, where each segment on the display has a single corresponding pin to control it not SPI.

Setup You should consult the datasheet for your display driver first see datasheets folder and I have included some brief instructions on how to wire everything up. If you have an LCD screen you will also need to connect the backplane and driver oscillators as below. The backplanes could be controlled using the arduino but I decided to keep thigs simple and avoid this. You can use any of the following characters to tell the library how your screen is wired to your driver: - minus.

They usually connect to the PCB via a strip of conductive rubber, which means that the enclosure has to keep both together.

Those tend to be the physically bigger ones. If the op wants something small, he's probably stuck with zebra strip connectors. I don't like them much either, but there is probably little choice in very small displays. Honestly, this is the only kind of structure that will fit your mechanical constraints.
