New Products – Spring 2024
As always, the Crystalfontz team has been working to bring you new and exciting display solutions. This update includes a family of modules designed to integrate with the Raspberry Pi CM4, some transparent LCDs, a family of 2.8″ TFTs, and a few updates to products to ensure long availability with minimal design changes required.
Raspberry Pi CM4 Compatible Modules
New to our product line are two beautiful displays designed to work quickly and easily with the Raspberry Pi Compute Module 4. These displays are crisp 5″ displays with 720×1280 resolution and in-plane switching (IPS). These modules include easy mounting for compute module, and break out a ton of functionality onto a variety of headers.
Features include:
- 5 inch TFT, 1280×720 high pixel density, high-brightness display
- Multi-touch capacitive or non-touchscreen options
- Raspberry Pi CM4 based (quad-core 64bit SoC @ 1.5GHz, 1/2/4/8GB RAM options, microSD or 8/16/32GB eMMC storage options)
- A full Raspberry Pi standard 40 pin IO header
- Compact expansion header access to PCI-E, HDMI, SPI and Ethernet
- An extra six GPIO lines from an on-board I2C IO expander IC
- Battery backed up real time clock
- Flexible power supply options (barrel-jack, Micro USB or PCB header)
Available both as a non-touch module or a capacitive touch module, these display modules are a fantastic choice for your compute module based product!
Transparent LCDs
Also new are our transparent LCDs. We offer these transparent LCDs in two sizes – the 1.1″ transparent LCD and the 2.2″ transparent LCD. These displays hugely outperformed our expectations, so they are back ordered at the time of writing. We hope to be shipping them again in the next month or so!
If you’ve seen our DIY transparent LCD tutorial, these displays are like those, but done for you! These displays work with our graphic LCD adapter board.
2.8″ TFTs
Coming in on the diagonal between our popular 2.4″ and 3″ displays, we are now offering a 2.8″ display family. These displays are IPS, and support SPI interfacing in addition to 18-bit parallel and RGB. Plus, if you’re already using our 2.4″ displays, these displays use the same controller IC and have the same resolution, so it’s easy to migrate to a slightly larger TFT.
This family includes a non-touch version and a resistive touch version as off-the-shelf offerings. If you’re interested in a capacitive touch version, let us know! Minimum order quantities may apply.
Part Number Changes
As much as we try to avoid changing parts, sometimes it’s inevitable. These parts have recently been updated to ensure they are available for the long run.
First up is this little 122×32 pixel graphic LCD. The controller IC went end-of-life forcing us to adopt a different controller IC. This new model is fully compatible with the previous version.
Next is this large 40×4 character display. The bezel on this display was updated to improve manufacturability.

“As a new user to the world of LCD electronics, Kelsey has been a Godsend in providing the hand-holding I needed to get my project up and running despite my own efforts at fouling things up! :-)” – Owen M
“Kelsey got me through changing code for a new LCD in only two short emails.” – Phillip V
“The agent that I talked with (Kelsey), is technically sound and she knows what she is doing. The support is what made my job easier to get started with the different display technologies. Thank you!” – Vatsal S
Custom Images on EVE Displays
A frequent question that is received by our support team is how to load custom images on our EVE lineup of displays. Due to differences in the EVE processors between boards and other factors, depending on the display you have, the process may change. The different processes for the boards have been outlined below. The only software required is the handy EVE Asset Builder (EAB) available on Bridgetek’s website here.
Images from SD Card
The process outlined below is for an SD card loaded with your image. To program an image to the Arduino’s flash memory without the use of an SD card, keep reading!
EVE BT817 Boards
Our displays that use this processor on their EVE carrier board are as below:
- 5″ displays: CFA800480E3-050SC, CFA800480E3-050SN, CFA800480E3-050SR, CFA800480E3-050SW
- 7″ displays: CFAF1024600B0-070SC-A1
- Select the image you would like to display (perhaps the most important step!), in this example, I will be using a Crystalfontz splash screen for our 5″ lineup
- Open EAB and load the image selected. Specify the output folder and select BT81x as the EVE product range. Set the output format to “COMPRESSED_RGBA_ASTC_8x8_KHR”, check compressed, and set the ASTC Preset to thorough
- Press convert and open the output directory. Rename the resulting ***.bin file to “splash.a8z” (the extension must be changed)
- Copy the renamed file to the SD card
- In our demo code, for the display you have, set “PROGRAM_FLASH_FROM_USD” to 1. This line is located in the CFA10XXX_defines.h file. Once changed, upload the sketch to the Arduino/Seeeduino
- Open the serial monitor at 115200 baud and copy the output lines corresponding to lines 92-101 of CFA10100_defines.h or 96-105 of CFA10108_defines.h Not getting an output? Perhaps “DEBUG_LEVEL” in CFA10XXX_defines.h is set to “DEBUG_NONE”. Please try again with it set to “DEBUG_STATUS” or “DEBUG_GEEK”
- Paste the lines in CFA10XXX_defines.h overwriting the existing data
- Set “PROGRAM_FLASH_FROM_USD” to 0 and set “BMP_DEMO” to 1 and upload the sketch
- Your image should now be displayed
EVE FT811 Boards
Our displays that use this processor on their EVE carrier board are as below:
- 2.4″ displays: CFA240320E0-024SC, CFA240320E0-024SN
- 3″ displays: CFA240400E1-030TC, CFAF240400E1-030TN
- 3.9″ displays: CFA480128E0-039TC, CFAF480128A0-039TN-A1-1
- Select the image you would like to display. Like with the case of the previous example, I will be using a Crystalfontz splash screen
- Open EAB and load the image selected. Specify the output folder and select FT81x as the EVE product range. Set the output format to “RGB565” and uncheck compressed
- Press convert and open the output directory. Rename the resulting ***.raw file to “SPLASH.RAW” (the extension must be changed and the name is case sensitive)
- Copy the renamed file to the root of the SD card, set “BMP_DEMO” to 1 in “CFA10XXX_defines.h” and upload the sketch
- Your image should now be displayed
Images from Flash
What if you need to change the images written to the Arduino’s flash memory (when “LOGO_DEMO” or “LOGO_PNG_0_ARGB2_1” is set to 1)? Well look no further, the process is outlined below.
PNG Logos
- Select the image you would like to display. Preferably a small 300×300 (or similar) image
- Provide the image as an input to the following website: https://lvgl.io/tools/imageconverter
- Set the color format to “CF_RAW” and the output format to “C array”. Uncheck dithering and click convert
- Open the resulting file (in .c format). Copy the array of data to the location where the PNG file is stored, “Round_Logos.cpp”, “CFA240320E0_024Sx_Splash_PNG.cpp”, etc.
- At the bottom of the .c file generated previously, copy the size to the corresponding header file (of the previous cpp that the array was copied to)
- Set “LOGO_DEMO” to 1 (“LOGO_PNG_0_ARGB2_1” should be set to 0) and upload the sketch
- Your image should now be displayed
ARGB2 Logos
- Select the image you would like to display, preferably a small 300×300 (or similar) image
- Index the image to 4 colors (this can be done using the editing software GIMP). This is done to reduce the size of the image
- Once indexed, load the image to EAB. Select FT81x as the EVE product range and the output format as ARGB2. Check compressed
- Select convert and open the output directory. Provide the ***.bin file as an input to the following website: https://lvgl.io/tools/imageconverter
- Set the color format to “CF_RAW” and the output format to “C array”. Uncheck dithering and click convert
- Open the resulting file (in .c format). Copy the array of data to the location where the ARGB2 file is stored, “Round_Logos.cpp”, “CFA240320E0_024Sx_Splash_ARGB2.cpp”, etc.
- At the bottom of the .c file generated previously, copy the size to the corresponding header file (of the previous cpp that the array was copied to)
- Set “LOGO_DEMO” and “LOGO_PNG_0_ARGB2_1” to 1 and upload the sketch
- Your image should now be displayed
