The LCD and keypad module gives you a handy 53 keys display, 5 buttons and a controllable backlight, plug it straight in on top of your handheld computer board or other project shields. The display is set behind the shield for a low profile fitment and nice look and we’ve included panel mounting screw holes in the corners.

Some LCD screens are advertised with a contrast range of 1000:1, which is 10 stops, but that is under ideal conditions, which never occur in practice. Of course, if you are in very dim light, the eye will produce visual purple over a 10-15 minute adaptation time to increase its sensitivity (but not its DR) by several stops. Added all up, the eye system is capable of over 14 stops of DR, but that’s cheating somewhat. Instantaneously, it’s close to matching the range of of current LCD screens, and current LCD screens are actually often set too bright to comfortably view in a darkened room. Dynamic range capability isn’t about a particular viewing medium, it is the flexibility to alter the photos in post-process and choose the parts of the dynamic range you want in your final print/wallpaper/web view, etc.

Handheld computers—also known as personal digital assistants (PDAs)—are small, portable devices that offer users many of the same features and capabilities as desktop computers at a fraction of the size. Although the terms “handheld computer” and “PDA” are often used interchangeably, handhelds tend to be larger and feature miniature keyboards, while PDAs tend to be smaller and rely on a touch screen and stylus for data entry.

The size of handheld computers ranges from credit card to small notebook computer, and the available features and power generally increase with greater size. Most handheld computers utilize a liquid crystal display (LCD), which acts as both an input and an output device. Only the larger PDAs feature keyboards, and most others require users to enter information on a touch screen, either by tapping letters with a stylus or by writing letters on the screen, which the device interprets using handwriting-recognition software. In the future, many handheld units are expected to incorporate voice-recognition technology.

In fact, using pulsepal, the output triggers’ rise looked as two very similar curves that crossed each other at the nanosecond scale. To solve that, we took out the pulsepal and just used a T connection in the bpod output to send the same signal to the two different NIDAQ ports in those cases that scanimage seemed to really require the signals to be identical. Now everything seems to work.
