# ESP-IDF-InkPlate
# ESP-IDF-InkPlate Version 0.9.0
A porting effort to the ESP-IDF framework for the e-Radionica InkPlate software that can be find [here](https://github.com/e-radionicacom/Inkplate-Arduino-library).
@ -6,7 +6,7 @@ A porting effort to the ESP-IDF framework for the e-Radionica InkPlate software
Beware that these classes are **not** re-entrant. That means that it is not possible to use them in a multi-thread context without proper mutual exclusion access control.
This project is a working example. You can build it using PlatformIO. It will draw a square and a straight line on the device display.

## Modifications done to the Arduino Inkplate Source code
@ -33,11 +33,33 @@ Some of these changes have been done partially and will be completed in subseque
- variables and method names are in lower_case
- all graphical libraries and class remains with their Arduino naming convention
- classes inheritence are reduced to insure independance of usage of the drivers group. By design, the grapphical portion remains as defined for the Arduino framework with some internal transformation to be more inline with C++.
- A TAG is added in the protected/private portion of driver classes in support of the ESP-IDF Logging mechanism (ESP_LOGX defines)
- A TAG is added in the protected/private portion of driver classes in support of the ESP-IDF Logging mechanism (ESP_LOGx defines)
- min() definition replaced with std::min()
- _swap...() definitions replaced with std::swap()
- String replaced with std::string (No PROGMEM support required with the ESP32)
### defines.hpp
The content is now at a bare minimum: DisplayMode enum class that defines both INKPLATE_1BIT and INKPLATE_3BIT modes. Also, BLACK and WHITE values for INKPLATE_1BIT mode.
As the DisplayMode is an enum class, it is then required to access the values as follow:
- DisplayMode::INKPLATE_1BIT
- DisplayMode::INKPLATE_3BIT
### graphics (.hpp, .cpp)
The class is now the owner of the _partial and DMemory4Bit frame buffers. As such, methods that where defined in Inkplate.hpp are relocated into that class, namely:
- clearDisplay()
- display()
- preloadScreen()
- partialUpdate()
They select the appropriate frame buffer and call the e_ink class methods.
This change is mostly transparent for the user application.
### SdCard
- The module is used only to initialize the ESP-IDF drivers (SPI and FAT filesystem are used). The card can then be accessed through the standard C++/C capabilities. All filenames located on the card must be prefixed with `/sdcard/`.
@ -48,6 +70,26 @@ Some of these changes have been done partially and will be completed in subseque
- the `bool drawXXXXFromSd(SdFile *p, ...)` methods are renamed `bool drawXXXXFromFile(FILE *p, ...)`. This allow for accessing files located in a SPIFFS partition (using `/spiffs/` filename prefix) as well as SDCard files (using `/sdcard/` filename prefix) or any other file system integrated with ESP-IDF.
- functions-like related to image / pixel manipulation present in `defines.h` have been migrated here. Namely: RED, BLUE, GREEN, READ32, READ16, ROWSIZE, RGB8BIT, RGB3BIT. They are now inline functions with appropriate types named red, blue, green, read32, read16, rowSize, rgb8Bit, rgb3Bit.
### mcp23017 (.hpp, .cpp)
This class is implementing a generic MCP23017 driver. It is instanciated in the inkplate_platform.hpp, depending on the type of Inkplate device:
- as mcp_int (for all Inkplate devices)
- as mcp_ext (for the Inkplate-10, and Inkplate-6).
### battery, touch_keys (.hpp, .cpp)
Those classes implement basic access to the battery and touch keys state.
### system class renamed InkplatePlatform
This name reflect more what it is. This class will is currently under eavy changes.
### FrameBuffer classes
A hierarchy of frame buffer classes has been added. These allow for flexible adaptation to the different
geometry of devices and pixel sizes.
## ESP-IDF configuration specifics for InkPlate devices
An InkPlate application requires some functionalities to be properly set up within the ESP-IDF. The following elements have been done for this project and can be used as a reference for other projects:
