Note

10.3inch e-Paper is big size screen, the glass panel and FPC is fragile, please be careful when use it for developing. we recommend you to reinforce the FPC with scotch tape when developing. Please connect all the cables before powering the device, the device cannot support hot-plug.

There are two versions, one is the raw panel and another is the HAT version. The driver board (IT8951) is required for raw panel, if you are the first time to buy this e-paper, recommend you choose HAT version which comes with the driver board.

Introduction

  • This product is a flexible e-Paper HAT (D), 10.3 inches, with a resolution of 1872×1404. It equips with IT8951 as the controller, can be controlled by USB/SPI/I80 interface, and supports partial refresh.
  • Compared with ordinary e-Paper screens, it is thinner and lighter.
  • It has the advantages of low power consumption, wide viewing angle, and clear display after power failure. It is often used in display applications such as e-book readers, ink screen displays, and industrial instruments.

Working principle

This product is an E-paper device adopting the image display technology of Microencapsulated Electrophoretic Display, MED. The initial approach is to create tiny spheres, in which the charged color pigments are suspending in the transparent oil and would move depending on the electronic charge. The E-paper screen display patterns by reflecting the ambient light, so it has no background light requirement. Under ambient light, the E-paper screen still has high visibility with a wide viewing angle of 180 degrees. It is the ideal choice for E-reading.(Note that the e-Paper cannot support updating directly under sunlight)

How to use

Working with Windows PC

  • Connect 10.3inch e-paper to IT8951 driver board as below

1200px-10.3inch-e-Paper-HAT-D-Manual-01.jpg

  • Connect USB interface of IT8951 driver board to PC, then connect PWR ONLY interface of IT8951 to 5V power adapter.
The refresh consumption of e-Paper is high, therefore, external power supply is required. You must first connect data cable then the power, otherwise, e-Paper cannot be recognized properly.

You can also download the newest bcm2835 library from its official website http://www.airspayce.com/mikem/bcm2835/
Copy the library you download to Raspberry Pi and install it withe commands below. You can also following the instruction on its website above
tar zxvf bcm2835-1.xx.tar.gz
cd bcm2835-1.xx
./configure
make
sudo make check
sudo make install
  • Download Demo codes of 10.3inch e-Paper HAT and test
git clone https://github.com/waveshare/IT8951-ePaper.git
cd IT8951-ePaper/Raspberry
sudo make clean
sudo make -j4
  • Check the VCOM data from the FPC
10.3inch-e-Paper-HAT-D-Manual-07.jpg
  • Run the example and use the VCOM value as a parameter as well as number 0
sudo ./epd -2.51 0
  • Expected result
    1. Display 16 gray bars in partial mode
    2. Draw figures and strings
    3. Display pictures in 1bp, 2bp, and 4bp modes
    4. Fast updating in A2 mode
    5. Display a gif
    6. Dispaly a demo for calculating the framerate
    7. Clear the display in Init mode

Working with STM32

Because IT8951 will cost big size of RAM, some of STM32 cannot support without external SDRAM device. So we here use Open429I as test board, Open429I integrates IS42S16400J (64-MBIT) SDRAM,has full memory to drive the 9.7inch e-paper.

Working with STM32, you can use SPI, I80 or I2C interface. SPI is simple and only a few of GPIOs are used, its speed can also meet the requirement of most applications. I80 is also simple and fast, however, it need to use lots of GPIO. I2C is every slow, which we don't recommend.

SPI

1) Hardware connection

Connect to STM32F429IGT6 (SPI)

Display pictures

For easy porting our demo code, we display picture with data matrix instead of file system.

We should first convert BMP picture to data matrix (arrays), and use it in demo code.

1) Prepare a BMP image, resize the picture to 800*600

2) Open BMP convert software, Click File->Open..-> to open the picture as below:

10.3inch-e-Paper-HAT-D-Manual-11.jpg

3) Click Image -> Convert to ->Gray256(8 BPP)

10.3inch-e-Paper-HAT-D-Manual-12.jpg

4) Click File ->Save As... ->Choose "C" bitmap file (*.c) -> input file name and click Save.

5) Choose 8 bit per pixel, click OK. A C file will be saved to your PC

6) Add the C file to keil project, delect unusable information

{
	IT8951LdImgInfo stLdImgInfo;
	IT8951AreaImgInfo stAreaImgInfo;
