E-book with Ameba (AMB23)

Details

Getting started with Ameba E-Book Project

The goal of this project is to build an E-book with AMB23.

1. Contents will be written into a text file and save in a SD Card.

2. The content in the text file will be read and display on to the E-paper display.

3. The contents will be split into pages based on the height and width of the E-paper display dimension.

4. Changing of pages can be done by pressing a button.

---

My plan is to add in the following functions to this project:

1. Long Text Wrap

2. User to be able to choose the orientation

3. Drawing of shapes

4. Add in page number as user flip the pages using button

5. Flip pages using button

The text in the text file is read from an SD card using the onboard micro SD card reader. A long text wrap function is implemented to change the line whenever the sentence approaches the limit of the E-paper width or height without a word being split. A shape drawing function is also implemented to allow users to draw shapes such as rectangle, circle, lines, etc.

Added a simple cover page for E-book.

Added button to change pages and text wrap

Long text are split into many pages and pages can be changed using a button. Page numbers are also added at the bottom right hand corner. The texts are being wrapped according to the size of the E-paper display so that sentence or word will not be cut off. Users can choose and set their preferred font size in the ino. file. Font Size choices: 16, 20, 24. Orientation of the E-book can also be chosen by the user. Orientation choices: 0^o, 90^o, 180^o, 270^o. When the last page is reached, it will return to page 1 after the button is pressed again.

Connection between AMB23 and E-paper Display

Take a look at the pin diagram for AMB23

get-start-3 and connect accordingly.

Busy - D21

Reset - D20

DC - D19

CS - D12

CLK - D11

DIN - D9

The pin numbers definition can be found in epdif.h .

#define RST_PIN 20
#define DC_PIN 19
#define CS_PIN 12
#define BUSY_PIN 21

Do note that Display Config should be set to B and Interface Config should be set to 0.

Connection between button and AMB23

Button pin is defined to be D2.

Button setting can be found in ino file.
int button = 2;
int buttonState = 1;

Really cool idea. When I was at university, I had a guy in my group who had an idea to pull this off. But he didn't make it. I studied at the university of pennsylvania, use https://studymoose.com/university/university-of-pennsylvania to learn more. The university really allows you to create something unique. There is everything for this condition, there would be only a desire.

Are you sure? yes | no
