This is a 2*16 character RGB LCD+Keypad plate for Raspberry Pi. We made improvements in the wiring connection based on the previous LCD display as well as left out the contrast adjustment function, so the product can be pretty easy to use, and users can spend time focusing on the most important projects.

The RGB LCD1602 display is integrated on the shield. It leads out Raspberry Pi’s GPIO ports for connecting more device. Besides, the shield adopts I2C interface, so you can realize the 16 million color combination of the LCD, backlight brightness adjustment, display control etc. To convenient your use on Raspberry Pi, there are 5 push-buttons integrated on the board to help you to switch display and configure functions, then you can easily build up your data monitor and small operating platform.

Whenever you come across a LCD that looks like it has 16 connectors it is most likely using a HD44780 controller. These devices provide the same pinouts making them relatively easy to work with. The LCD uses a parallel interface meaning that we will need many pins from our raspberry pi4 to control it. In this tutorial we will use 4 data pins (4-bit mode) and two control pins.

The data pins are straightforward. They are sending data to the display (toggled high/low). We will only be using write mode and not reading any data.

The register select pin has two uses. When pulled low it can send commands to the LCD (like position to move to, or clear the screen). This is referred to as writing to the instruction or command register. When toggled the other way (1) the register select pin goes into a data mode and will be used to send data to the screen.

Clock (Enable). Falling edge triggered Bit 0 (Not used in 4-bit operation) Bit 1 (Not used in 4-bit operation) Bit 2 (Not used in 4-bit operation) Bit 3 (Not used in 4-bit operation) Bit 4 Bit 5 Bit 6 Bit 7 Backlight LED Anode (+) Backlight LED Cathode (-)Before wiring, check that your LCD has an LED backlight, not an EL backlight. LED backlights use 10-40mA of power, EL backlights use 200+ma! EL backlights are often cheap to get but are not usable, make sure you don"t use one or you will overload the Pi. Some cheap LCDs that have LED backlights do not include a resistor on the LCD module for the backlight, if you"re not sure, connect a 1Kohm resistor between pin 15 and 5V instead of connecting directly. All Adafruit LCDs have LED backlights with built in resistors so you do not need an extra resistor!Wiring Diagram How to connect 16x2 LCD with Raspberry pi4

First, connect the Cobbler power pins to the breadboard power rail. +5.0V from the cobbler goes to the red striped rail (red wire) and GND from the cobbler goes to the blue striped rail (black wire)

In order to send data to the LCD, we are going to wire it up as follows Pin #1 of the LCD goes to ground Pin #2 of the LCD goes to +5V Pin #3 (Vo) connects to the middle of the potentiometer Pin #4 (RS) connects to the Cobbler #21 Pin #5 (RW) goes to ground Pin #6 (EN) connects to Cobbler #20 Skip LCD Pins #7, #8, #9 and #10 Pin #11 (D4) connects to cobbler #16 Pin #12 (D5) connects to Cobbler #12 Pin #13 (D6) connects to Cobber #1 Pin #14 (D7) connects to Cobber #25 Pin #15 (LED +) goes to +5V (red wire) Pin #16 (LED -) goes to ground (black wire)

In this example, I am going to install and use the library from Adafruit. It’s designed for Adafruit LCD boards but will also work with other brands as well. If your display board uses an HD44780 controller, then it should work with no issues at all.

LCD character displays are useful for displaying information without the need for an external monitor. Common LCD character displays can be connected directly to the GPIO pins, but such an approach requires the use of up to 10 GPIO pins. For scenarios that require connecting to a combination of devices, devoting so much of the GPIO header to a character display is often impractical.

Many manufacturers sell 20x4 LCD character displays with an integrated GPIO expander. The character display connects directly to the GPIO expander, which then connects to the Raspberry Pi via the Inter-Integrated Circuit (I2C) serial protocol.

There are many manufacturers of LCD character displays. Most designs are identical, and the manufacturer shouldn"t make any difference to the functionality. For reference, this tutorial was developed with the SunFounder LCD2004.

The device address for the GPIO expander depends on the chip used by the manufacturer. GPIO expanders equipped with a PCF8574 use the address 0x27, while those using PCF8574A chips use 0x3F. Consult your LCD"s documentation.

Another using declaration creates an instance of Lcd2004 to represent the display. Several parameters are passed to the constructor describing the settings to use to communicate with the GPIO expander. The GPIO expander is passed as the controller parameter.

I am trying to use a 16x2 LCD display with the I2C module on the back to display a constant readout of an HC-SR04 ultrasonic sensor. I have the ultrasonic sensor code working fine so it shouldnt be a problem right now but i cannot get the lcd to display properly.

I have followed this youtube tutorial (https://www.youtube.com/watch?v=fR5XhHY ... dex=2&t=0s) and the clock demo runs but displays nothing and the lcd demo displays only random characters.

I have tried attaching an image but i cant get the file size small enough but i have only the lcd connected currently with LCDvcc > RPI+5V LCD gnd > RPIgnd and the SDA and SCL pins connected using single female to female wires. Same as shown in the tutorial.

the lcd has a variable resistor on the back to adjust contrast so its not that either. I can clearly see characters its just that they are a load of nonsense

they were yes i just hastily assembled the circuit to post the first pic of the connections. I fixed it and it was recognised using i2cdetect -y 1 and i still ended up with the nonsense characters with them the right way around.

When I use this type of LCD I normally use the gpio to drive the LCD directly, when ever I have seen a corrupted display like that it normally means there is a bad connection between the pi gpio and the LCD, so may be you have a bad connection between the LCD and the I2C module.

I have decided to just buy another LCD/I2C module since they are cheap while I wait for suggestions/fixes. Just incase it is a faulty LCD - I will report back if this is the case.

Seeing as it"s only the small PCB on the back of the LCD that"s i2c, unless the i2c board does a check of some kind to make sure the LCD is attached and working I don"t see why it would not be possible to have a bad connection or a faulty LCD and the i2c board still be recognised.

Still running Raspbian Jessie or Stretch on some older Pi"s (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B, B+, and a A+) but Buster on the P3B+, P4B"s & P400. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

Level-shifters definitely needed for 5V displays esp. if the I2C module is PCF8574-based or, if you can w/o affecting other things, reduce the LCD/module supply to ~4.4V (that ensures that the pi"s 3.3V is seen as a "high" by the PCF8574) see: http://www.cpmspectrepi.uk/raspberry_pi ... iPlus.html

There"s some code at https://github.com/DougieLawson/Raspber ... nified_LCD which will test one of those backpack displays (using 0x27 for the I²C address). After you"ve built it pcfCG will demonstrate the character generator and pcflcd will show a clock and your IP address.

So I bought a new display but I am having the same issue so it is very unlikely that it was a problem with the board. Is there any chance something like this could happen due to damage to the internals of the RPI but still have it recognise the I2C device using i2cdetect? I am out of my depth here and just grasping at straws.

Whilst I agree that it"s unlikely to be "a problem with the (display) board" I doubt it due to "damage to the internals of the RPI ..." since you have had some characters displayed". I"m not a Python programmer so I can"t comment on Python programs (apart from the default timings as in my previous post). What I can say is I"ve successfully driven a selection of PC8574-based I2C to LCD display modules with, for the 5V devices, level shifters** on the I2C bus or a reduced (5V --> 4.4V) supply, or I2C running at 3.3V for a 3.3V LCD. My code is "C" based, using the wiringpi library and is part**** of my GpioCDemoSoftware: http://www.cpmspectrepi.uk/raspberry_pi ... tware.html There is also an example within wiringpi itself and @DougieLawson has suggested code of his to try.
