# lilybook
Little ePaper reader for ESP32 ### ePaper library for ESP32
---
#### Features
* Support for **GDEH029A1** / **SSD1608** based ePaper modules in 4-wire SPI mode. Support for other controllers will be added later
* **emulated** 4-bit gray scale mode
* **SPI displays oriented SPI driver library** based on *spi-master* driver
* Combined **DMA SPI** transfer mode and **direct SPI** for maximal speed
* **4-bit Grayscale mode** or **1-bit b/w mode** can be selected during runtime
* SPI speeds up to **20 MHz** are tested and works without problems
* **Demo application** included which demonstrates most of the library features
* **Graphics drawing functions**:
* **EPD_drawPixel** Draw pixel at given x,y coordinates
* **EPD_drawLine** Draw line between two points
* **EPD_drawFastVLine**, **EPD_drawFastHLine** Draw vertical or horizontal line of given lenght
* **EPD_drawLineByAngle** Draw line on screen from (x,y) point at given angle
* **EPD_drawRect**, **EPD_fillRect** Draw rectangle on screen or fill given rectangular screen region with color
* **EPD_drawRoundRect**, **EPD_fillRoundRect** Draw rectangle on screen or fill given rectangular screen region with color with rounded corners
* **EPD_drawCircle**, **EPD_fillCircle** Draw or fill circle on screen
* **EPD_drawEllipse**, **EPD_fillEllipse** Draw or fill ellipse on screen
* **EPD_drawTriangel**, **EPD_fillTriangle** Draw or fill triangle on screen
* **EPD_drawArc** Draw circle arc on screen, from ~ to given angles, with given thickness. Can be outlined with different color
* **EPD_drawPolygon** Draw poligon on screen with given number of sides (3~60). Can be outlined with different color and rotated by given angle.
* **Fonts**:
* **fixed** width and proportional fonts are supported; 8 fonts embeded
* unlimited number of **fonts from file**
* **7-segment vector font** with variable width/height is included (only numbers and few characters)
* Proportional fonts can be used in fixed width mode.
* Related functions:
* **EPD_setFont** Set current font from one of embeded fonts or font file
* **EPD_getfontsize** Returns current font height & width in pixels.
* **EPD_getfontheight** Returns current font height in pixels.
* **set_7seg_font_atrib** Set atributes for 7 segment vector font
* **getFontCharacters** Get all font's characters to buffer
* **String write function**:
* **EPD_print** Write text to display.
* Strings can be printed at **any angle**. Rotation of the displayed text depends on *font_ratate* variable (0~360)
* if *font_transparent* variable is set to 1, no background pixels will be printed
* If the text does not fit the screen/window width it will be clipped ( if *text_wrap=0* ), or continued on next line ( if *text_wrap=1* )
* Two special characters are allowed in strings: *\r* CR (0x0D), clears the display to EOL, *\n* LF (ox0A), continues to the new line, x=0
* Special values can be entered for X position:
* *CENTER* centers the text
* *RIGHT* right justifies the text horizontaly
* *LASTX* continues from last X position; offset can be used: *LASTX+n*
* Special values can be entered for Y:
* *CENTER* centers the text verticaly
* *BOTTOM* bottom justifies the text
* *LASTY* continues from last Y position; offset can be used: *LASTY+n*
* **EPD_getStringWidth** Returns the string width in pixels based on current font characteristics. Useful for positioning strings on the screen.
* **EPD_clearStringRect** Fills the rectangle occupied by string with current background color
* **Images**:
* **EPD_jpg_image** Decodes and displays JPG images
* Limits:
* Baseline only. Progressive and Lossless JPEG format are not supported.
* Image size: Up to 65520 x 65520 pixels
* Color space: YCbCr three components only. Gray scale image is not supported.
* Sampling factor: 4:4:4, 4:2:2 or 4:2:0.
* Can display the image **from file** or **memory buffer**
* Image can be **scaled** by factor 0 ~ 3 (1/1, 1/2, 1/4 or 1/8)
* Image is displayed from X,Y position on screen/window:
* X: image left position; constants CENTER & RIGHT can be used; *negative* value is accepted
* Y: image top position; constants CENTER & BOTTOM can be used; *negative* value is accepted
* Image is converted to **4-bit Gray Scale mode**
* **Other display functions**:
* **EPD_fillScreen** Fill the whole screen with black, white or gray scale
* **compile_font_file** Function which compiles font c source file to font file which can be used in *EPD_setFont()* function to select external font. Created file have the same name as source file and extension *.fnt*
* **Global wariables**
* **orientation** current screen orientation
* **font_ratate** current font rotate angle (0~395)
* **font_transparent** if not 0 draw fonts transparent
* **font_forceFixed** if not zero force drawing proportional fonts with fixed width
* **text_wrap** if not 0 wrap long text to the new line, else clip
* **_fg** current foreground color for fonts
* **_bg** current background for non transparent fonts
* **_angleOffset** angle offset for arc, polygon and line by angle functions
* **image_debug** print debug messages during image decode if set to 1
* **cfont** Currently used font structure
* **EPD_X** X position of the next character after EPD_print() function
* **EPD_Y** Y position of the next character after EPD_print() function
* **_gs** use 4-bit Gray scale if set to 1
* **_width** screen width (larger dimension) in pixels
* **_height** screen height (smaller dimension) in pixels
---
Full functions **syntax and descriptions** can be found in *EPD.h* and *EPDspi.h* files.
Full **demo application**, well documented, is included, please **analyze it** to learn how to use the library functions.
---
#### Connecting the display
To run the demo, attach display module to ESP32. Default pins used are:
* mosi: 23
* sck: 18
* CS: 5 (display CS)
* DC: 26 (display DC)
* RST: 27 (display RESET)
* BUSY: 32 (display BUSY output)
The display can be powered from 3.3V or from **GPIO pin**. See *EPDspi.h* for configuration options.
**If you want to use different pins, change them in** *EPDspi.h*
Using *make menuconfig* **select tick rate 1000** ( → Component config → FreeRTOS → Tick rate (Hz) ) to get more accurate timings
---
#### How to build
Configure your esp32 build environment as for **esp-idf examples**
Clone the repository
`git clone https://github.com/loboris/ESP32_ePaper_example.git`
Execute menuconfig and configure your Serial flash config and other settings. Included *sdkconfig.defaults* sets some defaults to be used.
Navigate to **ePaper Display DEMO Configuration** and set **SPIFFS** options.
Select if you want to use **wifi** (recommended) to get the time from **NTP** server and set your WiFi SSID and password.
`make menuconfig`
Make and flash the example.
`make all && make flash`
---
#### Prepare **SPIFFS** image
*The demo uses some image and font files and it is necessary to flash the spiffs image*
**To flash already prepared image** *components/spiffs_image/spiffs_image.img* execute:
`make copyfs`
---
You can also prepare different SFPIFFS **image** and flash it to ESP32.
Files to be included on spiffs are already in **components/spiffs_image/image/** directory. You can add or remove the files you want to include.
Then execute:
`make makefs`
to create **spiffs image** in *build* directory **without flashing** to ESP32
Or execute:
`make flashfs`
to create **spiffs image** in *build* directory and **flash** it to ESP32

// Height (height of the visible pixels)
// xOffset (start X of visible pixels)
// xDelta (the distance to move the cursor. Effective width of the character.)
// Data[n]
// NOTE: You can remove any of these characters if they are not needed in
// your application. The first character number in each Glyph indicates

// Any width is fine and does not need to be fixed.
// The data bits are packed to minimize data requirements, but the tradeoff
// is that a header is required per character.

// Any width is fine and does not need to be fixed.
// The data bits are packed to minimize data requirements, but the tradeoff
// is that a header is required per character.

// Any width is fine and does not need to be fixed.

* middle of the file system at block boundary. In addition, it is not checked
* if the page size is actually correct. If it is not, weird file system sizes
* will be returned.
*
* If this function detects a file system it returns the assumed file system
* size, which can be used to set the phys_size.

/*
* spiffs_check.c
*
* Contains functionality for checking file system consistency
* and mending problems.
* Three levels of consistency checks are implemented:
*
* Look up consistency
* Checks if indices in lookup pages are coherent with page headers
* Object index consistency
* Checks if there are any orphaned object indices (missing object index headers).
* If an object index is found but not its header, the object index is deleted.
* This is critical for the following page consistency check.
* Page consistency
* Checks for pages that ought to be indexed, ought not to be indexed, are multiple indexed
*

// on the fd update mechanism. The cache lives in the closed file descriptors.

/* SPIFFS layout
*
* spiffs is designed for following spi flash characteristics:
* - only big areas of data (blocks) can be erased
* - erasing resets all bits in a block to ones
* - writing pulls ones to zeroes
* - zeroes cannot be pulled to ones, without erase
* - wear leveling
*
* spiffs is also meant to be run on embedded, memory constraint devices.
*
* Entire area is divided in blocks. Entire area is also divided in pages.
* Each block contains same number of pages. A page cannot be erased, but a
* block can be erased.
*
* Entire area must be block_size * x
* page_size must be block_size / (2^y) where y > 2
*
* ex: area = 1024*1024 bytes, block size = 65536 bytes, page size = 256 bytes
*
* BLOCK 0 PAGE 0 object lookup 1
* PAGE 1 object lookup 2
* ...
* PAGE n-1 object lookup n
* PAGE n object data 1
* PAGE n+1 object data 2
* ...
* PAGE n+m-1 object data m
*
* BLOCK 1 PAGE n+m object lookup 1
* PAGE n+m+1 object lookup 2
* ...
* PAGE 2n+m-1 object lookup n
* PAGE 2n+m object data 1
* PAGE 2n+m object data 2
* ...
* PAGE 2n+2m-1 object data m
* ...
*
* n is number of object lookup pages, which is number of pages needed to index all pages
* in a block by object id
* : block_size / page_size * sizeof(obj_id) / page_size
* m is number data pages, which is number of pages in block minus number of lookup pages
* : block_size / page_size - block_size / page_size * sizeof(obj_id) / page_size
* thus, n+m is total number of pages in a block
* : block_size / page_size
*
* ex: n = 65536/256*2/256 = 2, m = 65536/256 - 2 = 254 => n+m = 65536/256 = 256
*
* Object lookup pages contain object id entries. Each entry represent the corresponding
* data page.
* Assuming a 16 bit object id, an object id being 0xffff represents a free page.
* An object id being 0x0000 represents a deleted page.
*
* ex: page 0 : lookup : 0008 0001 0aaa ffff ffff ffff ffff ffff ..
* page 1 : lookup : ffff ffff ffff ffff ffff ffff ffff ffff ..
* page 2 : data : data for object id 0008
* page 3 : data : data for object id 0001
* page 4 : data : data for object id 0aaa
* ...
*
*
* Object data pages can be either object index pages or object content.
* All object data pages contains a data page header, containing object id and span index.
* The span index denotes the object page ordering amongst data pages with same object id.
* This applies to both object index pages (when index spans more than one page of entries),
* and object data pages.
* An object index page contains page entries pointing to object content page. The entry index
* in a object index page correlates to the span index in the actual object data page.
* The first object index page (span index 0) is called object index header page, and also
* contains object flags (directory/file), size, object name etc.
*
* ex:
* BLOCK 1
* PAGE 256: objectl lookup page 1
* [*123] [ 123] [ 123] [ 123]
* [ 123] [*123] [ 123] [ 123]
* [free] [free] [free] [free] ...
* PAGE 257: objectl lookup page 2
* [free] [free] [free] [free] ...
* PAGE 258: object index page (header)
* obj.id:0123 span.ix:0000 flags:INDEX
* size:1600 name:ex.txt type:file
* [259] [260] [261] [262]
* PAGE 259: object data page
* obj.id:0123 span.ix:0000 flags:DATA
* PAGE 260: object data page

* Look up consistency
* Checks if indices in lookup pages are coherent with page headers
* Object index consistency
* Checks if there are any orphaned object indices (missing object index headers).
* If an object index is found but not its header, the object index is deleted.
* This is critical for the following page consistency check.
* Page consistency
* Checks for pages that ought to be indexed, ought not to be indexed, are multiple indexed

// accessed almost every second time a file is opened. Another example could be
// a log file that is often opened, written, and closed.

// on the fd update mechanism. The cache lives in the closed file descriptors.
// When closed, the fd know the whereabouts of the file. Instead of forgetting

* Created on: Jun 15, 2013
* Author: petera

/* SPIFFS layout
*
* spiffs is designed for following spi flash characteristics:
* - only big areas of data (blocks) can be erased
* - erasing resets all bits in a block to ones
* - writing pulls ones to zeroes
* - zeroes cannot be pulled to ones, without erase
* - wear leveling
*
* spiffs is also meant to be run on embedded, memory constraint devices.
*
* Entire area is divided in blocks. Entire area is also divided in pages.
* Each block contains same number of pages. A page cannot be erased, but a
* block can be erased.
*
* Entire area must be block_size * x
* page_size must be block_size / (2^y) where y > 2
*
* ex: area = 1024*1024 bytes, block size = 65536 bytes, page size = 256 bytes
*
* BLOCK 0 PAGE 0 object lookup 1
* PAGE 1 object lookup 2
* ...
* PAGE n-1 object lookup n
* PAGE n object data 1
* PAGE n+1 object data 2
* ...
* PAGE n+m-1 object data m
*
* BLOCK 1 PAGE n+m object lookup 1
* PAGE n+m+1 object lookup 2
* ...
* PAGE 2n+m-1 object lookup n
* PAGE 2n+m object data 1
* PAGE 2n+m object data 2
* ...
* PAGE 2n+2m-1 object data m
* ...
*
* n is number of object lookup pages, which is number of pages needed to index all pages
* in a block by object id
* : block_size / page_size * sizeof(obj_id) / page_size
* m is number data pages, which is number of pages in block minus number of lookup pages
* : block_size / page_size - block_size / page_size * sizeof(obj_id) / page_size
* thus, n+m is total number of pages in a block
* : block_size / page_size
*
* ex: n = 65536/256*2/256 = 2, m = 65536/256 - 2 = 254 => n+m = 65536/256 = 256
*
* Object lookup pages contain object id entries. Each entry represent the corresponding
* data page.
* Assuming a 16 bit object id, an object id being 0xffff represents a free page.
* An object id being 0x0000 represents a deleted page.
*
* ex: page 0 : lookup : 0008 0001 0aaa ffff ffff ffff ffff ffff ..
* page 1 : lookup : ffff ffff ffff ffff ffff ffff ffff ffff ..
* page 2 : data : data for object id 0008
* page 3 : data : data for object id 0001
* page 4 : data : data for object id 0aaa
* ...
*
*
* Object data pages can be either object index pages or object content.
* All object data pages contains a data page header, containing object id and span index.
* The span index denotes the object page ordering amongst data pages with same object id.
* This applies to both object index pages (when index spans more than one page of entries),
* and object data pages.
* An object index page contains page entries pointing to object content page. The entry index
* in a object index page correlates to the span index in the actual object data page.
* The first object index page (span index 0) is called object index header page, and also
* contains object flags (directory/file), size, object name etc.
*
* ex:
* BLOCK 1
* PAGE 256: objectl lookup page 1
* [*123] [ 123] [ 123] [ 123]
* [ 123] [*123] [ 123] [ 123]
* [free] [free] [free] [free] ...
* PAGE 257: objectl lookup page 2
* [free] [free] [free] [free] ...
* PAGE 258: object index page (header)
* obj.id:0123 span.ix:0000 flags:INDEX
* size:1600 name:ex.txt type:file
* [259] [260] [261] [262]
* PAGE 259: object data page
* obj.id:0123 span.ix:0000 flags:DATA
* PAGE 260: object data page
* obj.id:0123 span.ix:0001 flags:DATA
* PAGE 261: object data page
* obj.id:0123 span.ix:0002 flags:DATA
* PAGE 262: object data page
* obj.id:0123 span.ix:0003 flags:DATA
* PAGE 263: object index page
* obj.id:0123 span.ix:0001 flags:INDEX
* [264] [265] [fre] [fre]
* [fre] [fre] [fre] [fre]
* PAGE 264: object data page
* obj.id:0123 span.ix:0004 flags:DATA
* PAGE 265: object data page
* obj.id:0123 span.ix:0005 flags:DATA

INTRODUCTION
Spiffs is a file system intended for SPI NOR flash devices on embedded targets.
Spiffs is designed with following characteristics in mind:
* Small (embedded) targets, sparse RAM without heap
* Only big areas of data (blocks) can be erased
* An erase will reset all bits in block to ones
* Writing pulls one to zeroes
* Zeroes can only be pulled to ones by erase
* Wear leveling
