So, just de-solder it. Bronnen: geekistuff. Bron nen : circuitdigest. U8g2 is a monochrome graphics library for embedded devices. U8g2 also includes U8x8 library:. Bron nen : www. Het scherm is volledig programmeerbaar en kan een combinatie van afbeeldingen en tekst weergeven. ST is a chip manufactured by Sitronix and has support for Chinese alphabet. This is enough for most users and keep in mind that while you are in graphic mode, you can draw any character you want, anywhere on the display.

In text mode, the LCD has 4 rows of 16 characters.

I recently received a 2. This is a 3. I have a DUE on hand that has been woefully neglected for some moths, so i thought it would be a great opportunity to use it. I tried to write code to see how fast the OLED would update, basically i did an analog read and print routine, thats when i noticed how painfully slow the update was, to the point that digits got garbled and looked terrible.

How could this be? I am pretty sure it has something to do with not using the hardware SPI, the library is obviously implementing a software spi and i am sure that slows it down a bunch, but is that the only issue? Does anyone know a way to implement the hardware pins with the u8glib library?

I would love to use this display as it is well suited for my application, but at its current performance level its pretty useless.

Hi Which is the actual U8glib constructor you use? Another cause for a slowdown often is to call analog read inside the u8glib "picture loop". Sequence should be: a read analog value b store the value in a variable c execute picture loop, output value from variable Maybe you can also post your code for further discussion.

I also saw another possible solution further down in the displays section i want to try. I am curious about the due hardware spi implementation, i must have missed that one in the long list. I am using the NHDGR constuctor sorry if thats not exactly the way the constuctor is listed, im on my phone.

Hi Code: [Select]. Code: [Select]. Did you pull out the analogRead from the inner loop? But i agree, also with the analogRead inside the loop, it should be much faster.

I have not yet tested Arduino 1. Latest tested release is 1. Thanks for all your help and your detailed responses, means a lot to a newb like me. I'll play with the analog read code more tomorrow, but right now i have to call it a night.Anmelden Ein neues Profil erzeugen. Erweiterte Suche. Sind die gravierend? Mehr geht hier wohl nicht. Kann ich die ignorieren? Kein Erfolg. Wo sollte die Bibliothek hin? Welches bitte? Muss ich das tun oder ergibt sich diese Funktion aus der Aktivierung des Graphicscontroller-board mit integriertem SDschacht?

Bei mir hat es geklappt. Das LCD sollte funken, tut es aber nicht. Was hat der zu sagen? BB hoffentlich! Geebee Antworten Zitieren. Geebee, vielleicht hast Du es gelesen Das Video hat mir Mut gemacht, liebe Dickbrettbohrer, und nachdem ich mir 2 Tage lang welchen angespart hatte, habe ich gestern nacht mal kurz an dem Teil geschraubt und gerupft.

Dieses konnte ich erst jetzt sehen, da ich das LCD mittels des Jumpers auf der Vorderseite zum Dauerleuchten verdammt habe. Ich habe den Mittelsteg auf dem Kabel, sofern sichtbar, fett schwarz hervorgehoben.

Die farbige Ader beider Kabel liegt im Bild jeweils oben.Ordinary LCD can only print simple text or numbers within a fixed size. This Graphical LCD is having low power consumption and also suitable for battery power portable device. It have wide operating voltage range 2.

Select the format shown in the above image and save the file for further process. After saving it open that file using Notepad and you will get the Hex code of the image. As shown in the picture below, choose the Export option to save the file in the xbm format:. Open the xbm file using Notepad and you will get the HEX code as shown in picture below. Then you can include the library like below:. So, we are using the serial mode and RS pin set to High 1 for chip enabled and Low 0 for chip disabled.

Now, for printing the image we need to place the Hex code of the image in the below code. You can print any other image all you just need to do is paste the hex code of the image.

Setting up pixel, color and intensity by using the code below. The void loop continues to print the text and image after the given delay. Then we have printed the image using picture function which will stay on screen for 3 seconds. This will continue till the power supply is turned on. You, will get content and image printed on the Graphical LCD, as shown in the video given below.

Nice project. Yes edit the program to display the bitmap first in the setup function and then add the rest in your loop. Hello, it is very useful. Thank you.

I personally think it is not fair to compare dfrobot a company with u8glib open source project without budget. But ok, if you do not like it, just do not use it. But maybe you could give a hint what you do not like with u8glib.

Maybe it can be improved. Regarding you question: It can not be answered. You are right, but both are terrible library anyway for medium user. About u8glib, dont take it personally, i would really to see the u8glib improved, but it's not user friendly at all.

For example, i cant write a clean and functional code, while i have to write a DO every time to print something? Thank you for your answer. Obviously i have created u8glib for my own projects. Your second point is unfortunately true: There is no clear command. This is probably the most requested command in u8glib, but i simply can add a usefull clear command. This is based on the concept for u8glib and the initial purpose of this library: U8glib was designed to consume as little RAM as possible.

It got designed to fulfill specific requirements RAM consumption but unfortunately U8glib became famos to some extend. A "traditional" library with a normal clear function would require bytes of controller memory to build the picture which then must be transfered to the display. But still some users like me want to use the x64 pixel display.

And this is why I wrote U8glib. Ok, there is no clear function, but you can use display types on the Uno. And this is something unique I agree: For a simple monochrom x64 display, you may look for an other option.Ordinary LCD can only print simple text or numbers within a fixed size.

Thanks for your contribution. Thanks again for the quickstart. I've figured out the u8glib now - pretty powerful. It would be nice to be able to control that light programatically. You're cool. I am having fun with this display - appreciate the help.

In got the display light up but Arduino code don't verify. Thank you. Hi Carlos - I've tried the current version of the u8glib ver. I am using Arduino IDE ver. Which versions are you using? Finally worked after downloading the library a few more times. I have no idea why?

Hmm, so how would this differ for use with the Due? Thank you for the write up. Hi Incognition - It looks like there was some work on the u8glib library last spring with ver. It is definitely worth looking into. Hi Incognition - Using ver. Works exactly as described on a Nano - perfect introduction to get the screen up and running for the first time - thank you! Note: This does not work with the Arduino Due.

To use an SPI connection, use the pins in the hooded connection on the module. The other switch controls the backlight. See the section near the bottom of the post. Anonymous January 4, at PM.
