I've come across an LCD module, VERY tiny unit, in an existing design. It's a small, 4 char. by 2 line unit, measuring .75" x .75" x .0625". I'm interested in using this module for a design I'm working on, but the unit is completely devoid of any markings, and the manufacturer isn't lettin' on who makes it. I'm nearly certain it's a production model, not manufactured by (or specifically for) this company, since it's not a high-quantity product. I originally thought it may be a Hitachi HD44780-style controller, since the connector on the module has 14 pins (it's not backlit), but it only has 9 of the pins connected; The first 3 and last 2 pins are not. Since every hitachi design I've ever seen uses the first 3 pins for vcc, vss, and voo, I'm pretty sure it's not hitachi-based. Also, I tracked down the vcc/vss lines and tried feeding it a few hitachi commands in 4-bit, with several variations of possible pinouts, with no response. Anyway, does anyone know anything about a production model module like this? My searches have all turned up blank so far...

Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why itâ€™s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
