The Parallax Serial LCDs (liquid crystal displays) can be easily connected to and controlled by a microcontroller using a simple serial protocol sent from a single I/O pin. The LCD displays provide basic text wrapping so that your text looks correct on the display. Full control over all of their advanced LCD features allows you to move the cursor anywhere on the display with a single instruction and turn the display on and off in any configuration. They support visible ASCII characters Dec 32-127). In addition, you may define up to eight of your own custom characters to display anywhere on the LCD. An onboard piezospeaker provides audible output, with full control over tone note, scale and duration using ASCII characters Dec 208–232.

The LCDs currently for sale are updated to Revision F. Basic functionality remains the same, but power requirements and the layout of the backpack have changed. Please see the documentation for information on your model.

This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn’t supported by Parallax, but it’s possible to make this connection with a few extra parts.

As mentioned earlier, the commands that send text, numbers, formatters and control characters to a serial LCD are remarkably similar to the ones you use with DEBUG command.· That"s not just a coincidence either.· The DEBUG command is actually a special case of a command called SEROUT.· The SEROUT command has many uses, some of which include sending messages to serial LCDs, other BASIC Stamps, and computers.·

In this activity, you will display and animate text messages, numeric values.· The SEROUT command will be your tool for accomplishing these tasks.· You will use the SEROUT command to send text, numbers, control characters and formatters to the Parallax serial LCD.· As you will soon see, the text, numbers, and formatters are identical to ones you use with the DEBUG command.· The control characters will be a little different, but with a little practice, they"ll be just as easy to use as the DEBUG command"s CR, CLS, HOME, and CRSRXY control characters.···

Unlike the Debug Terminal, the serial LCD needs to be turned on with a command from the BASIC Stamp.· The LCD has to receive the value 22 from the BASIC Stamp to activate its display.· Here"s the PBASIC command for sending the serial LCD the value 22:

SEROUT 14, 84, [noparse]/noparse][/size][/font][font=Times New Roman][size=2][color=#ff0000]"See this?"[/color][/size][/font][font=Times New Roman][size=2], 13, [/size][/font][font=Times New Roman][size=2][color=#ff0000]"The LCD works!"[/color][/size][/font][font=Times New Roman][size=2

Ö·······If the LCD didn"t display properly, go through the instructions leading up to this program, and verify that each one was completed correctly.· Also double-check your wiring, program, and the SW settings on the back of the LCD.· Also try resetting power to your Board of Education.

Remember that 22 turns the display on, and 21 turns it off?· You can use these control characters to make the LCD text flash on and off.· All you have to do is replace the END command with this loop:

Most of the formatters that worked for displaying numbers with the Debug Terminal can also be used with the Parallax Serial LCD.· The DEC formatter is probably the most useful, but you can also use DIG, REP, ASC, BIN, SDEC, and most of the others.· For example, if you want to display the decimal value of a variable named counter, you can use commands like this:

Aside from demonstrating that you can display variable values on the serial LCD, this program also shows what happens if the text displayed tries to go beyond 16 characters in line 1; it wraps to line 2.

The LCD"s control characters are different from the DEBUG command"s control characters.· For example, HOME, and CRSRXY just don"t have the same effect they do with the Debug Terminal.· Take a look at the LCD documentation"s Command Set section.· It lists all the valid control characters for the LCD; here are a few more examples from the list:

The values from 128 to 143 and 148 to 163 are particularly useful.· Figure 10 shows where these values will place the cursor.· You can use values from 128 to 143 to place the cursor at characters 0 to 15 on the top line of the LCD.· Likewise, you can use values from 148 to 163 to place the cursor on characters 0 to 15 of the bottom line.

After placing the cursor, the next character you send the LCD will display at that location.· For example, here is a SEROUT command with an optional pacing value set to 200 ms.· This command will display the characters "L", "I", "N", "E", "-", and "2", evenly spaced across the top line, one character every 200 ms.

The LCD will still automatically shift the cursor to the right after each character, making it easy to place the cursor and then display a message.· For example, you can also place the cursor on character 7 of the top line and then display "ALL", then move the cursor to character 6 of the bottom line and display "DONE!" like this:

The display portion of the OLED module measures 0.95″ diagonal and contains 96 x 64 RGB pixels. Each pixel can be set with 16 bits of resolution for a large range of colors. OLED technology does not require a backlight, which results in a colorful, high contrast display.

Parallax is an ambient light-rejecting technology that features a micro-layered optical lens system that rejects light. This new technology mimics the look of a television when it is on and when it is off, but without the glare from windows or lighting fixtures. With extremely wide viewing angles, no speckle and no glare, the surface is ideal for applications in Pro AV as well as Home Theater. Additionally, the surface is flexible, ships in a roll and is easy to install. Each layer of Parallax plays a role in preserving the image that is reflected back to the viewer in high ambient light environments. Some layers absorb light while one special layer is shaped like a microscopic saw-tooth that blocks light from above resulting in the preservation of high-contrast, bright images in brightly lit environments.

Already our motionless posture in front of a screen suggests that we’re experiencing a resurgent version of a flat-earth belief system—one that makes it hard, painful, and even dangerous to look beyond the firmament. You might fall over the edge or be expelled. However, looking straightforwardly at the device will let you forget about this abyss, as you’re always busy with a new feed. But the abyss of other depths—like the one found in Jim’s Dog—will not just go away if we simply ignore it. As Paul Virilio points out, the invention of new technologies is also the invention of new accidents. By inventing the plane, you also invent the plane crash.5 Whether or not I want it to, the light on my LCD extends beyond the content on my screen and beyond the display’s glass stack in both directions, towards me but also towards sources I can’t trace with my eyes—the inventor or owner of the file format, the assembly line of the camera manufacturer, the room that hosts the server, the water that cools the data center, the nuclear accident that happened in the power plant, and so forth. A junkyard full of world-making stuff blows in my face when the light hits it, regardless of the image that shows on my feed.

On the website Gizmag, the physicist Brian Dodson recommends scraping off the polarizing filter of one’s monitor in order to deal with the implications of visible and invisible layers of surfaces.6 When the first layer of an LCD display is removed, the images disappear and only the light remains. Polarizing glasses can aid the eyes to still see the content of the screen if necessary. Even though Dodson’s main motivation is privacy in public spaces, the intervention also serves another purpose. It’s a first step to making the stack’s depth tangible and to creating a contact zone with the light itself.

The English word “pig” refers to the animal raised and sold by farmers, while the French-derived word “pork” refers to the edible meat from the pig. The gap between these two words relays the class dimensions of the animal, its producers and its consumers. The dual use of wording marks the distance between those who produce and those who consume: the prosperous Norman conquerors who could afford to eat porque from the pig raised by the underprivileged Saxon farmers. Japanese philosopher and literary critic Kojin Karatani refers to this very gap as the parallax dimension—a phenomenon that appears when we are confronted with irreducible antimonies and the opposed positions they produce. Karatani says that radical critique starts with asserting antimony as irreducible and renouncing all attempts to close the gap between positions. True critique, then, involves seeing things neither from one’s own viewpoint nor from the viewpoint of others, but rather recognizing the reality that is the structural interstice between positions.8

Parallax is the reason why we have a perception of depth, why we see 3-D. It occurs when a thing is viewed or screened from two positions, like the position of our eyes. But what if the positions are further apart then our own eyes?

What if this parallax is in fact the default experience of viewing—of staring at the irreducible antimonies the system constantly produces? The siege on Ohlauer Strasse had this parallax dimension, and not surprisingly, it was undecidable where inside and outside were. The positions are structurally so far apart that they cannot create coherent space together. For the time being, one has to endure the nausea that the parallax produces in order to see and formulate a radical critique of the system that produces such antimonies. Blocking the police siege made the space jump, change size, multiply. Together with the police line and the rooftop withdrawal, the irreducible gap became visible.

I am back at the corner of Ohlauer Strasse, but instead of facing a police line defending Europe’s outside borders in the middle of my neighborhood, I am stopped by the traffic light whose red signal I awkwardly obey—not because I normally do, but because there is a police car right behind my bicycle. The light turns green and I continue my journey, cycling past the intersection along with all the other bicycles, cars, pedestrians. On the surface, the street corner has turned back to normal after ten days of an exceptional police operation and the protests that accompanied it. The refugee activists left the occupied school’s roof after continuous, nerve-splitting threats of eviction and negotiations with municipal officials. All of this effort led only to a minimal agreement: officials would tolerate the remaining forty activists in the building, but they rejected the other demands concerning rights of residence and free movement. So in fact the state of exception that had been very visible and tangible a few days earlier was not resolved, but was rather folded in and tucked away behind the surface of normality. Underneath this surface, which lets traffic flow, shops open, cyclists pay attention to traffic lights, and which makes the neighborhood livable, rests a continuous state of exception in which mobility is not a human right. But this state has retreated back to another layer, one that is hardly visible even though the banners are still covering the facade of the school and the refugees have to show ID when they leave and enter the building. Even though the events that happened on the same surface a few days earlier have accidentally allowed a glimpse into the depths of the stack and revealed the parallax dimension of the European system, it is tempting to adjust your eyes back to the smoothness of restored order.

To send a command to the GPS Receiver Module, the user must first send the header string, which is “!GPS” without the quotes, followed by the specific command byte of their choice.

This stems from the fact that the LCD controller itself does not inherently support the function and in fact treats the ASCII codes for and as displayable characters instead of control codes.

In my opinion the basic LiquidCrystal library should concentrate on implementing all of the capabilities of the LCD controller and no more. If people want a library that more closely emulates a CRT (or LCD) terminal that is fine, but I think it should be done in a different library.
