Relevant Displays and Kits

Do you need help getting started with your graphic LCD and CFA10110 adapter board? This getting started guide helps bring up any of the following displays or kits:

If you need a guide for the CFAG12864T3 or CFAG12864U3 using a generic breakout board, check out this getting started guide or our DIY transparent display video. Speaking of videos, click here if you’d prefer this bring up guide as a video.

Quick comparison of different options

Why are these Graphic LCDs good?

The family of U3 and T3 monochrome graphic LCD displays are great because they’re low power, thin, easily readable, and quick to develop with. The U3 family is 2.2″ on the diagonal, while the T3s are 1.1″. Versions with “TFH” in the part number include a frame backlight that makes these displays readable in dark environments while the “NFH” displays are reflective and rely on external light sources.

These graphic LCDs are a great way to provide low-fuss information in a project. They can display any shape you want, so no worrying about an included font table not including necessary characters. Plus, they’re quicker to develop for than a full color TFT display. They have extremely low power requirements, especially if the backlight is selectively used. They can even be converted to create a DIY transparent display.

We designed the CFA10110 adapter board for these displays to further simplify incorporating these displays. The board breaks the tail out to a 16-pin 0.1″ header, so no soldering is necessary to connect to the display. Further, 2 x 2-56 threaded mounting standoffs make securing this display module a breeze. And jumpers on the board handle switching between SPI and parallel interfaces.

Getting Started

This guide will walk through setting up the display with a CFA10110 in SPI mode. Wiring information for the parallel modes can be found in the datasheets available in the righthand sidebar of the product pages or in the demo code.

• A display with CFA10110 adapter board (see list above)
• 3.3v microcontroller (e.g., Seeeduino v4.2)
• USB cable (e.g., WR-USB-27)
• Jumper cables (e.g., 6″ WR-JMP-Y40 or 3″ WR-JMP-41)
• Headers (e.g., CFAPN01855)
• A sketch

Wire the Board to your Microcontroller:

Using the jumper wires, connect the CFA10110 board to the microcontroller. We’re using an Arduino clone, thus “ARD”.

// ARD    | LCD  | Color
// ---------+--------+-------
// 3v3    | 3v3  |  Red
// GND    | GND  |  Black
// D8     | DC   |  Green
// D9     | RES  |  Blue
// D10    | CS   |  Purple
// D11    | D7   |  Gray
// D13    | D6   |  Orange

Connect the Display to the Adapter Board

If you ordered a kit or display module ending in E1-1 or E1-2, you can skip this step. We did this for you.

If you ordered the CFA10110 separately from the display, insert the tail of the display shiny pins down into the ZIF connector. You shouldn’t need a lot of force to insert the tail into the connector (thus “Zero Insertion Force”).

Once the tail is firmly seated into the connector, close the connector by pushing down on the black tab.

Run A Sketch

The final step is to run a sketch. Connect your controller to your computer with the USB cable and upload your sketch. If you’re using our sketch, check that the display defined in LCD_low.h is the same as the display you just wired up. It changes the contrast and a few other settings and can make the display difficult to read if the wrong one is defined. The section that needs to be checked looks like this:

#define CFAG12864T3 (1)
#define CFAG12864U3 (0)

// Define the display type.
#define display_type CFAG12864T3

To use a U3 display, simply switch the 1 and 0 and change “#define display_type CFAG12864T3” to “#define display_type CFAG12864U3”

The code uses some different names for the pins than are written on the board. Here’s a copy the table from the code with a column listing the names from the code and the pin names from the CFA10110:

Use the Backlight

For the modules that include a backlight, connect a power source to the A and K tabs on the backlight frame. Check the datasheet of the module to ensure you provide the correct backlight voltage and current. The T3 module requires less power than the U3 module.
