This 2×16 character LCD Module with BLUE Backlight uses an I2C interface to communicate with the host microcontroller. This budget-conscious LCD is used on projects requiring the display of text, data, or ASCII characters of all types. Connect to Vcc, Gnd, SDA (serial data line), and SCL (serial clock line). This is a 5VDC device and will be found on the I2C bus at address 0x27 / 0x3F.

I just bought a 16x2 and I2C interface to it. Everything seems to be working fine (not sure if 4 or 8 bit?) but the only problem is refresh rate. When scrolling or fast changing text it is not visible because the "shadow" of the previous char. The only way to make it better is to set contrast with potentiometer to very low that text is actually black not white (it is negative display BLUE with White text).

Do you know what is the problem? I am seeing all of those youtube videos where they are even doing some nice animations with very good FPS but I am not able to display single text faster than ~800ms.

both are giving the same results. When I try scroll example it is even worse as I cannot read anything. There is this kind of shadow where the pixels were lit. As I wrote the only way to get rid of it is to set minimum contrast where text is black, but that should be the point of negative diplay right that text is white (on blue in this case)

The I2C interface is 4-bit. The eight bits of the interface chip are used for 4 data bits, Enable, Read/~write (not actually used), Register select and backlight. There is essentially no advantage in speed or otherwise, in attempting to use an 8-bit mode.

Since you know what you are going to write and what you have written, then it is simply not useful to either clear the display or write all blanks to it, simply (set the cursor,) write the new text and any further blanks required to cover the previous. This also applies to the common problem of leading zero suppression and fixed positioning of numbers.

Finally, the behaviour you observe with the brief "after-shadow" is in fact perfectly normal behaviour for this sort of LCDs (unlike video displays with few-millisecond response times). It is also temperature-dependent.

Nope I tried both and the result is the same. Maybe it is just crappy LCD or I2C interface, in the end it is from china. Although it is fine for temp readings with 1s refresh. I read something bad resistor in some of the diplays causing a lag where solution is to use busy flag.

Finally, the behaviour you observe with the brief "after-shadow" is in fact perfectly normal behaviour for this sort of LCDs (unlike video displays with few-millisecond response times). It is also temperature-dependent.

If you want to dim the backlight with a clean PWM signal, you would need to remove the connection of the backlight LED to the control chip, and replace it with a PWM signal from one of the Arduinos" pins.

You might need to use a transistor if the backlight needs a higher current and a resistor if the current needs to be limited (meaning if there is no resistor on the board of your display).

A basic misunderstanding is that proportional dimming of the backlight is necessary or appropriate. There are three modes in which you might want the backlight to operate; day at full brightness, night at reduced brightness, and off.

In any application, only two of these modes will generally be necessary. The backlight may be dimmed by substituting the jumper on the backpack with a resistor. A default minimum brightness may be set by a resistor connecting either pins 1 and 16, or 2 and 15, depending on the design of the backpack. These two controls may be used together if you never want the original maximum brightness.

And for the record, the drive voltage has nothing at all to do with the speed at which the HD44780 (equivalent) LCD driver is updated with new display data. It actually operates just fine - and equally fast - at 3.3 V as there are variants of the 1602 modules which operate at this voltage.

Certainly at a lower voltage, the LCD panel itself might be slow but in fact, if you lower the drive voltage (which is actually the contrast voltage) below about 4.2 V, you simply have no display at all. The variants of the 1602 modules which operate at 3.3 V incorporate a charge pump to bring the contrast voltage back up toward 4.8 V.

It might be the case that LCD panels in general which are designed to operate at lower voltages, are slower, but the working contrast voltage for any given panel, particularly those multiplexed such as the 1602 and similar displays, is within a strictly limited range.

This is LCD 1602 Parallel LCD Display that provides a simple and cost-effective solution for adding a 16×2 White on Liquid Crystal Display into your project. The display is 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight.

This is great blue backlight LCD display. It is fantastic for Arduino based project. This LCD1602 LCD Display is very easy to interface with Arduino or Other Microcontrollers.

This display overcomes the drawback of LCD 1602 Parallel LCD Display in which you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily in this product, an I2C adapter is directly soldered right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding.

If you already have the I2C adapter soldered onto the board like in this product, the wiring is quite easy. You should usually have only four pins to hook up. VCC and GND of course. The LCD display works with 5 Volts. So we go for the 5V Pin.

The values shown on the display can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.

If you want to add some visual output to your Arduino projects, you’ll need a display. If you need only a little to display, the Standard LCD 16x2 Display is a quite good solution. RoboticsBD

This is the great yellow/blue backlight LCD Display. It is fantastic for Arduino-based projects. This Standard LCD 16x2 with Yellow/Blue Backlight is very easy to interface with Arduino or Other Microcontrollers.

The values shown on the display can be either simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing. RoboticsBD

One thing to consider is you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily there exists an I2C adapter that you can solder right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding. We have the same LCD module with a pre-assembled I2C adapter, click on the name below to check it

Note: The I2C configuration simulates a PCF8574T chip that controls the LCD module. Normally, you wouldn"t have to worry about this as the LiquidCrystal_I2C library takes care of the communication with the chip.

#includeLiquidCrystallcd(12,11,10,9,8,7);voidsetup(){lcd.begin(16,2);// you can now interact with the LCD, e.g.:lcd.print("Hello World!");}voidloop(){// ...}

You can define custom characters using the createChar method of the LiquidCrsytal (or LiquidCrystal_I2C) library. The custom characters are the first 8 characters in the font, with indexes from 0 to 7. You can print them to the LCD

#includeLiquidCrystallcd(12,11,10,9,8,7);uint8_theart[8]={0b00000,0b01010,0b11111,0b11111,0b11111,0b01110,0b00100,0b00000,};voidsetup(){lcd.createChar(3,heart);lcd.begin(16,2);lcd.print(" I \x03 Arduino");}voidloop(){}
