That’s probably why you need to reevaluate today. Asking the right questions during this process clarifies the conditions you need to work successfully with the LCD display supplier.

Most of the review process is about asking the right questions about your needs to the supplier. Knowing exactly what display requirements the new LCD manufacturer should meet will inform you that they should what are the functions?

Monochrome TFT displays, and color TFT displays, you may need OLED or other technology, each display manufacturer offers different processing costs and minimum order quantity.

There is a significant difference between the demand for 2,000 and 200,000 screens per year, not only in large quantities but also in determining whether LCD vendors can effectively meet the demand for mass-produced displays.

Essentially, electronics are updated fast, right? How much of an impact will it have on your business if the new display vendor can’t keep up? Do you have an effective response?

Depending on the impact of display changes, suppliers will need to have appropriate configuration controls and obsolescence mitigation in place to ensure that your supply chain is uninterrupted throughout the life cycle of the final product.

Whether you need a JIT order, late inventory, or less than the lead time order, you will determine what LCD display manufacturers need to use to ensure seamless integration.

Compare multiple display vendors to see how well each vendor matches your list. It’s not always about cost. If the display vendor can’t compete at your core By working with the wrong vendor, you are likely to find higher ancillary costs and higher overall system-level costs.

These displays are straightforward to use and are a great way to provide a user interface on many projects where you need more info than simple LED indicators or 7-Segment displays can provide since these are full alphanumeric displays with 2 lines of 16 characters each.  For an interactive display, pairing this type of display with a rotary encoder to navigate and select menu items on the display can provide a very nice user interface.

The display is composed of a 16 character x 2 line LCD display with a blue backlight and white characters.  Each of the characters are composed of a 5 x 8 dot matrix for good character representation.

The backlight has a potentiometer for adjustment of the contrast of the display for best viewing.  If the potentiometer is turned too far in one direction or the other, the display will appear blank or solid squares will appear instead of characters.  If this happens, just fiddle with the adjustment until it gives the best display.

Note:  The non-uniformity in the picture is due to the protective film covering the display playing a trick on the camera.  The display has nice uniformity.

This display incorporates an I2C interface that requires only 2 pins on a MCU to interface with and it has good library support to get up and running fast.   The I2C interface is a daughter board attached to the back of the LCD module.

We also offer the raw 16×2 displays without the I2C interface.  Those have a parallel bus interface that requires many pins on the MCU to control.  For most applications it is generally easiest to stick with the I2C interface version like this one.

The mikroBasic PRO for dsPIC30/33 and PIC24 provides a library for communication with Lcd (with HD44780 compliant controllers) in 4-bit mode via SPI interface.

For MCUs with multiple SPI modules it is possible to initialize all of them and then switch by using the SPI_Set_Active() routine. See the SPI Library functions.

Want to display sensor readings in your ESP8266 projects without resorting to serial output? Then an I2C LCD display might be a better choice for you! It consumes only two GPIO pins which can also be shared with other I2C devices.

True to their name, these LCDs are ideal for displaying only text/characters. A 16×2 character LCD, for example, has an LED backlight and can display 32 ASCII characters in two rows of 16 characters each.

If you look closely you can see tiny rectangles for each character on the display and the pixels that make up a character. Each of these rectangles is a grid of 5×8 pixels.

At the heart of the adapter is an 8-bit I/O expander chip – PCF8574. This chip converts the I2C data from an ESP8266 into the parallel data required for an LCD display.

If you are using multiple devices on the same I2C bus, you may need to set a different I2C address for the LCD adapter so that it does not conflict with another I2C device.

An important point here is that several companies manufacture the same PCF8574 chip, Texas Instruments and NXP Semiconductors, to name a few. And the I2C address of your LCD depends on the chip manufacturer.

So your LCD probably has a default I2C address 0x27Hex or 0x3FHex. However it is recommended that you find out the actual I2C address of the LCD before using it.

Connecting I2C LCD to ESP8266 is very easy as you only need to connect 4 pins. Start by connecting the VCC pin to the VIN on the ESP8266 and GND to ground.

After wiring up the LCD you’ll need to adjust the contrast of the display. On the I2C module you will find a potentiometer that you can rotate with a small screwdriver.

Plug in the ESP8266’s USB connector to power the LCD. You will see the backlight lit up. Now as you turn the knob on the potentiometer, you will start to see the first row of rectangles. If that happens, Congratulations! Your LCD is working fine.

To install the library navigate to Sketch > Include Libraries > Manage Libraries… Wait for Library Manager to download the library index and update the list of installed libraries.

Filter your search by typing ‘liquidcrystal‘. There should be some entries. Look for the LiquidCrystal I2C library by Frank de Brabander. Click on that entry, and then select Install.

The I2C address of your LCD depends on the manufacturer, as mentioned earlier. If your LCD has a Texas Instruments’ PCF8574 chip, its default I2C address is 0x27Hex. If your LCD has NXP Semiconductors’ PCF8574 chip, its default I2C address is 0x3FHex.

So your LCD probably has I2C address 0x27Hex or 0x3FHex. However it is recommended that you find out the actual I2C address of the LCD before using it. Luckily there’s an easy way to do this. Below is a simple I2C scanner sketch that scans your I2C bus and returns the address of each I2C device it finds.

After uploading the code, open the serial monitor at a baud rate of 115200 and press the EN button on the ESP8266. You will see the I2C address of your I2C LCD display.

But, before you proceed to upload the sketch, you need to make a small change to make it work for you. You must pass the I2C address of your LCD and the dimensions of the display to the constructor of the LiquidCrystal_I2C class. If you are using a 16×2 character LCD, pass the 16 and 2; If you’re using a 20×4 LCD, pass 20 and 4. You got the point!

First of all an object of LiquidCrystal_I2C class is created. This object takes three parameters LiquidCrystal_I2C(address, columns, rows). This is where you need to enter the address you found earlier, and the dimensions of the display.

In ‘setup’ we call three functions. The first function is init(). It initializes the LCD object. The second function is clear(). This clears the LCD screen and moves the cursor to the top left corner. And third, the backlight() function turns on the LCD backlight.

After that we set the cursor position to the third column of the first row by calling the function lcd.setCursor(2, 0). The cursor position specifies the location where you want the new text to be displayed on the LCD. The upper left corner is assumed to be col=0, row=0.

lcd.scrollDisplayRight() function scrolls the contents of the display one space to the right. If you want the text to scroll continuously, you have to use this function inside a for loop.

lcd.scrollDisplayLeft() function scrolls the contents of the display one space to the left. Similar to above function, use this inside a for loop for continuous scrolling.

If you find the characters on the display dull and boring, you can create your own custom characters (glyphs) and symbols for your LCD. They are extremely useful when you want to display a character that is not part of the standard ASCII character set.

CGROM is used to store all permanent fonts that are displayed using their ASCII codes. For example, if we send 0x41 to the LCD, the letter ‘A’ will be printed on the display.

CGRAM is another memory used to store user defined characters. This RAM is limited to 64 bytes. For a 5×8 pixel based LCD, only 8 user-defined characters can be stored in CGRAM. And for 5×10 pixel based LCD only 4 user-defined characters can be stored.

Your imagination is limitless. The only limitation is that the LiquidCrystal_I2C library only supports eight custom characters. But don’t be discouraged, look at the bright side, at least we have eight characters.

After the library is included and the LCD object is created, custom character arrays are defined. The array consists of 8 bytes, each byte representing a row of a 5×8 LED matrix. In this sketch, eight custom characters have been created.
