SDGG12864-68 Graphic LCD

Hello,
I am using SDGG12864-68 graphic LCD and want to print 4x4 characters in single page vertically. The display data RAM stores the dot data for the LCD. It has a 64 (8 page x 8 bit ) x 128 bit structure.
Currently, I am not able to print/display two 4x4 characters in single page at a time in single page.

This is a classic ST7565R based display. Not sure, if I understood your problem correctly, but U8g2 exactly solves this page problem. I have also created a suitable font fntgrpu8g · olikraus/u8g2 Wiki · GitHub and added some other fonts from internet fntlist8 · olikraus/u8g2 Wiki · GitHub

We are currently utilizing the 128x64 graphic LCD with the RL78/G14 microcontroller, interfaced through SPI. We're encountering challenges in displaying characters effectively and seek your assistance.

Specifically, we'd like to confirm if the 128x64 supports Case3 and Case4 scenarios. We've attached a snapshot for your reference. Your insights on the compatibility of these cases with the LCD would be highly valuable.

case 3 and 4 are supported by u8g2.

6

Is it possible in FSTN Transflective Positive Mode Graphic LCD(Control IC: ST7565R) ?

7

U8g2 will work with any type of LCD as long as the controller is supported.

Can I interface it with other MCUs like Renesas,PIC.
Please forward 128x64 display(SPI) part number.

Can I interface it with other MCUs like Renesas,PIC.

U8g2 is a Arduino Library. So the answer is yes, if Renesas or PIC include are supported by the Arduino Environment.

Please forward 128x64 display(SPI) part number.

If you need support here, then I would say, it is your duty to provide details regarding the display. I don't know from where we should take the part number.

Is QC12864B support above requirements?
It has ST7920 controller.

11

Displays with both ST7920 and ST7565R with the display size of 128x64 pixel are supported by U8g2.

I am interfacing QC12864B with RL78/G14 using parallel communication.
But display is not responding.
Please comment on below code.

13

My comment is to get an Arduino Board and use the same to interface the LCD together with U8g2.

Hello sir,

I have interface the QC12864B with RL78/G14 using SPI communication protocol.

I have display images and characters on the LCD screen.

Now I need char font library.

  1. Buy an Arduino (compatible) board
  2. Download Arduino IDE
  3. Connect your display
  4. Download U8g2
  5. Select one of the > 1000 fonts from u8g2 or build your own font for u8g2 lib
