2 line 16 character lcd display datasheet price

The easiest way would be to stick a transistor inline with the power lead of the lcd and turn it off just before the cpu goes into the low power state.

This product worked great. I wrote a tutorial about manually writing data to the display using dips switches and push buttons. http://volatileinterface.com/2015/05/30/using-a-hd44780-lcd-display-in-4-bit-mode/

Completely useless, I have no idea what happened but when I wire it up according to the tutorial on arduinos site for the Hello World! LCD program, nothing but the backlight comes on. Also the pins are flipped from where they are in the schematic. Total cluster fuck of a product.

So apparently the product works fine, and I apologize to all those at sparkfun. I should be on the arduino forums tell them that the tutorial is a cluster F**k and not this item. for those who had the same problem, you have to connect pin 15 Vin and pin 16 to GND, everything on the tutorial is correct.

I just realized I forgot the bridge connections over the cnter of the breadboard to actually connect the data lines to the LCD. It works now I think I need to adjust the contrast or something. The text on the display is more visible when looking at the display from an angle.

I just bought this and thought it had the HD44780 chipset but now I started looking at the datasheet for the pin interface descriptions and I realize that it has the KS006U chipset? Is the datasheet wrong or is the sparkfun description wrong? Or maybe they are basically the same chipset? I"m confused right now. Do I need to buy a different LCD?

HD44780 is more a standard that a chipset at this point. there are tons of different chipsets that use the same protocols. like how people say "allen wrench" instend of saying hex key. HD44780 is the LCD equivilent of X86 instruction set. the cool think is you can lean how to use the 16x2, and then use the same code on everything from 8x1 to 40x4 displays.

You can simulate data on each pin of the HD44780 compatible LCD and see how it works, or if you are more advanced you can write directly your own scripts in the web browser to control the LCD, same as you would use them in the MCU code

Is there a flat cable assembly available for these? I"m OK using the 0.1" headers, but the electronics I need to hook up requires a cable interconnect. And I"d like it so that I can replace the LCD without desoldering it.

I?m considering using this in a battery powered device that will experience long periods of inactivity. During the inactive periods all system components will enter a low power stand-by or sleep state. This display does not appear to have a low power (uA) state.

This is a very late response, but anybody in this situation can simply connect the LCD in series with a MOSFET. YOu can then switch the LCD on and off from a microcontroller. Remember to leave all the microcontroller outputs floating because power can still flow into the LCD if you keep these in certain states.

You are the BEST!!! Thank you. It was worth registering just to post this message to you. I hope to participate further. There are a LOT of bugs in the Arduino sketches (Projects 1-23). Thanks again.

Working OK with Picaxe 20x2 but uses pins I would like to have free for i2c. So, I am getting bigger picaxe to go with it. Used 2 rectifier diodes in series for the voltage drop to 4.2v on the backlight and two 1k ohm resisters in series for the contrast. Looks good.

Thanks loophole! I got the display working fine using this link that link that was mentioned, http://arduino.cc/en/Tutorial/LiquidCrystal, but it was dim since the backlight was not working. After reading loophole"s comment and looking at datafile I applied 4.2V pin 15 and grounded pin 16, and all was GREAT!

The post that KHartley posted with regards to all the pin connections and using an Aduino mini pro, who then also got a reply from member 468163, that the code and everything worked.

I am using the exact components and have followed the exact pin configurations for the past 2 weeks, connecting then reconnecting, I have also tried different FTDI cables for uploading onto the Arduino pro mini. BUT have had no success, PLEASE help me as it is a basic issue I am sure but cannot find the solution, My 16*2 LCD lights up and also when I upload a program the arduino page reads that it has successfully uploaded (Done Uploading).

We"ve had customers order face plates through Ponoko for these LCDs and be pretty happy with it. Check around on the comments on other products and on the forum. You"ll probably find a lot of different examples of mounting solutions.

can this run in 8bit mode? I"m trying so hard to just wire up the 8 data lines and manually send the bits required for certain symbols. But it"s either stuck in 4bit mode, or I"m completely lost. My program is simple and I KNOW that it is sending the 1"s and 0"s down the appropriate lines but I can"t get a response at all. And I can succesfully apply the example code for liquid crystal. In class we just banged some bits into those old lcd"s and got the expected response... Is this one more advanced or something? Thanks, I really appreciate any help.

No matter what line I set the cursor at using lcd.setCursor(0,0), or lcd.setCursor(0,1), it will print everything on line 0. I"ve used the same LCD, different size before and never had this issue.

You should make the LCD"s connection pins on the bottom, like on the RGB backlit LCD"s (https://www.sparkfun.com/products/10862). I like standing them straight up and down on breadboards. If I tried that with this one, it would be upside down.

I"m having a problem with this lcd, I can"d print custom caracters, I tried the code that this site http://icontexto.com/charactercreator/ gives you when you create a custom char, tried some other examples, but nothing, I always get just two vertical bars on the second and fourth columns.

I love this little LCD! It works great. However, I"m having a wicked hard time finding hardware (i.e. self-clinching PEM stud) that I can use to mount this. The 2.5mm mounting holes are pretty small. I"m trying hard not to use glues.

I"m having problems with my contrast - it"s always either too high (washed out characters) or too low (can"t see the character) on separate spaces at the same time. No matter how I adjust it, each character seems to require a different contrast level. Help, please?

I"m also having trouble with LCD. I hooked up at 10kOhm pot, but when I upload the code it just gives me random pixels and characters. Is my Atmega on my Arduino Uno shot?

Like others have said, works well with liquidcrystal library and I also like to pwm the backlight with a fet on the low side. Looks really cool to have it fade out to 1 or 2% duty cycle standby mode when there has been no button presses/input in a while and then fade back in when you press a button.

Also no external resistor is needed for the backlight; just like almost all other 5v character LCDs this one has a series resistor right on the board. Mine is 130 ohms.

I was able to achieve much better contrast by applying a slightly negative voltage on the Vo pin (3). Minus 200 mV did the trick. I seem to remember that LCD"s used to have a negative output for just this reason. I don"t know what the rating of this pin is, so proceed with caution.

3) If you hook it to an Arduino, powering the LED backlight from a digital I/O pin will only source 40mA max. (PIC micros are even less), any more and you are overloading your output. Tie pin K (or 16) to ground, and A (or 15) will be the high side. If you design for 40mA, calculate the current limiting resistor to put between the I/O pin and pin A (or 15) of the LED backlight as follows: 5V-4.2V=0.8V and 0.8V/0.040A=20ohms however, be sure to measure the voltage across your current limiting resistor and calculate the actual current flowing to the LED just in case... don"t overload your Arduino I/O!

4) If you want to really drive it properly, you need more POWER! So grab an NPN transistor such as a 2N4401 or 2N2222 or 2N3904, and amplify your I/O. Hook a 220 to 330 ohm resistor between your I/O and the base of the NPN, hook the emitter of the NPN to ground, and the collector to the K pin (or 16) of the LED backlight. Hook a 5 to 10 ohm 1/4W resistor between the A pin (or 15) of the LED backlight and the 5V rail (make sure your 5V regulator can handle the extra 120-160mA of current you are going to be consuming)

Thanks to the guy who first pointed that for that bcklight to work one needs pin 15 on +4.2V and pin 16 on ground. Without that I was getting a pretty dim job.

I made it work by using the same schematic featured in the LiquidCrystal Arduino library page, except LCD pin 6 is hooked to a digital PWM instead of a potentiometer for controlling contrast.

Pretty cool little LCD. I had some problems initially with the 4bit LCD library, but after finding that the standard LiquidCrystal library supports 4-bit data lines it worked great.

The one thing that threw me off was that the standard (not extended) datasheet mentions that the backlight (BKL) can be driven by pins 1,2 or 15,16 -- however I found that I needed to apply 4.2v to pins 15,16 before the backlight would work. Easy fix, just misleading on the datasheet.

I"m very impressed. I followed the connections from the data sheet and set them up the same way the LiquidCrystal "Hello World" example sketch calls for, and the display worked perfectly with my Arduino Duemilanove. It does take some playing with the contrast potentiometer, but I quickly found the perfect setting. The display is sharp, clear, and cool white letters on a black background.

Ordered mine a week ago and finally got around to playing with it. I used the included LiquidCrystal.h for Arduino to run this thing. Very easy to use once you get it up and running. To get the contrast working I used a 3.3Kohm resistor going to ground, looks amazing. Not quite as bright as picture but I think I"m close. 2.2Kohm is too washed out and 6.8 Kohm nothing shows up. I can"t believe how much easier this is compared to the 68HC12. Uhhh, I"m going to have nightmares for the rest of my life.

Have you wired in the backlight? That tutorial doesn"t include wiring pins 15 and 16 on the lcd. I have hooked the backlight up to a pwm output so that I can turn it on and off via sketch.

I am also ahving this same problem. The LCD was great and easy to set up, but the brightness is really really poor. I installed a pot and all, but no dice.

Has anyone got this working with the LiquidCrystal or LCD4bit library? I am having quite a bit of trouble getting it to work reliably and am at the point where I am going to try and code my own library for it.

I"m also having heaps of trouble. I can sometimes get it to display text, maybe once out of every 30 attempts. And IF it decides to display anything it ends up garbling the message and locking up, not displaying the other strings in the sequence. Is this the LCD, my Arduino or the library? I tried using LCD4bit and a modified LiquidCrystal and they all yield the same, frustrating results.

Late reply, but I have trouble with this if I forget to add decoupling capacitors on the V+ line. Especialy using multiple serial to parallel converters at high data rates.

Great little lcd, for basic output, debugging etc. Very easy to interface, and looks very slick! If you need a basic no frills LCD, this is a good buy.

16×2 LCD is known as so because; it"s 16 Columns and a couple of Rows. There are tons of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. but the foremost used one is that the 16×2 LCD. So, it"ll have (16×2=32) 32 characters in total and every character are going to be made from 5×8 Pixel Dots.

Now, we know that each character has (5×8=40) 40 Pixels and for 32 Characters we will have (32×40) 1280 Pixels. Further, the LCD should even be instructed about the Position of the Pixels. Hence it"ll be a busy task to handle everything with the assistance of MCU, hence an Interface IC like HD44780is used, which is mounted on the backside of the LCD Module itself. The function of this IC is to urge the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen.
