In this tutorial we will look at interfacing KS display controller based JHDE display. There are many displays out there based on KS or. A x64 graphical LCD based on the KS controller chip is required. GLCDexample * * Basic test code for the Arduino KS GLCD library. * This code. ERMSYG-2 is “glcd x64 display graphic lcd module,ks+ks controller,stn lcd,yellow green led backlight,wide operating temperature.

KS Based Graphic LCD Interfacing with PIC18F – Part 2 –

Put the instruction on data port and give a high to low pulse on enable pin. RST is the reset pin, it is used to reset the entire display content by clearing whole of the display RAM. A given panel configuration will automatically determine which pin configuration file to use based on which board type is being used in the IDE.

In addition, if invoked, the raw data will be written to the VDIP1. It generates negative voltage required for the display.

If you’ve read and followed what is written above, make the image below full screen and observe it carefully.

Graphic LCD Library

Backorder notices are listed on your shopping cart. The last version of the glcd-arduino library v3 can be found here: This instruction sets the starting line of the display from the display data RAM.

I searched for a while and didn’t find a character LCD with big mm font size. Below function checks whether the display is in reset condition or OFF. Thanks to all for your hard work and sharing. Steve, if you are using Arduino then you no longer need to delete the.

Backorder notices are listed on your shopping cart. A small fraction of the glcds out there will need a reset pulse. Graphci you are ok with a GPL 3.


Starting with glcd v3, pin assignment is much more gaphic as any glcd function or data pin can be assigned to any Arduino pin. The library includes example ks108 and a readme. Perhaps using another board is a good alternative. Additional information can be found here: Below is the write timing diagram of the KS controller.

It has 8 data lines, 6 control lines and 6 power and display related pins. The software is lcs FontCreator2 and it can produce a header file that stores font definitions in program memory when included in your sketch.

In this article, we are discussing the implementation of different instructions. This looks straight forward for the command pinsbut not so for the data pins If the IDE fails to upload the Arduino when the glcd module’s reset line is attached to the Arduino board’s reset pin, see the troubleshooting guide below for remedies.

Write display data instruction writes a single byte of data from the data bus into the current address of the display RAM.

Write Your Own Review Only registered users can write reviews. We use these pins to transfer the data to the display RAM. We could also display bit-map images on it and stretching it little further we can make GUI’s and little animation, but that’s for another day. However it allows us the flexibility of creating fonts like Arial, times new roman etc.

Driving two panels from one Mega may be easier with the new library but its still going to be tricky because the port io makes heavy use of compile time optimization and with the current code it is not easy to compile two instances of the low level driver in the same sketch.

The 19 and 20 pins are Anode and cathode of backlit LED, limit the current through it by putting a resistor in the line. The remainder of this page is about GLCDv3 for those that would like to continue to use it. For reading instructions, data appears while E is at a high level. If you’ve used a 16×2 displayed, this works exactly like it. Unlike a 16 x 2 display, this does not have a character map for ascii values stored on its ROM.


I would be interested to hear more about RGC’s application and how the two displays would be used. Write Your Own Review Only registered users can write reviews. If it is between 64 andit is on the right controller.

There is also a negative voltage generator which outputs the negative voltage through Vee pin. E, F, G, etc Thanks to the likes of you and the rest of the Arduino community I have been able to dust-off my ancient by now skills in electronics and programming, and get all this stuff “working” in short order. They are not included in the firmware because they are either covered by other characteristics or they are not that significant.

During write instructions, after setting each pin of the corresponding value, enable pin must be applied with a high to low pulse. The default pin assignments for the glcd data pins are assigned to take advantage of this optimization. While any Arduino pin can can be used for any glcd data pin, using Arduino pins that are all in the same port and that are in consecutive bit order will give slightly higher performance.
