# Modifications done to the Arduino Inkplate Source code |
|||
|
|||
As you can expect, the ESP-IDF framework is quit different than the Arduino framework. The porting effort of the Inkplate source code done here is not just a transformation to make it runs, but also getting it inline with the available packages available with the ESP-IDF. Many aspects must be transformed in this regard. |
|||
|
|||
The code is also being transformed to be closer to C++ functionalities, targetting a stronger usage of the language elements that will sustain the author's software developement. A bit less C and more C++... |
|||
|
|||
The source code is divided in two major groups: the low-level device drivers group, under the `inkplate_platform` class, and the *mid-level* graphical group, under the `inkplate` class. The coupling between these groups is minimal: one can take the `inkplate-platform` and build on top of it without the graphical portion. As the graphical group rely on the drivers, it is inline with the Arduino counterpart. The coupling between the two groups is light as it is done through aggregation instead of inheritence. |
|||
|
|||
Here is a list of the changes being done: |
|||
|
|||
## Global changes |
|||
|
|||
Some of these changes have been done partially and will be completed in subsequent versions. |
|||
|
|||
- Give the overall drivers source code a transformation to use what is called *modern C++*, alligned with C++11 and beyond |
|||
- All .h files are renamed .hpp |
|||
- macro definitions (`#define`) are reduced to a bare minimum |
|||
- `enum class` are used everywhere possible in the drivers group. This reinforce source code documentation and compiler support for finding coding errors. |
|||
- source code filenames are all in lower_case. A lot easier visually to digg into the source folder and easier to remember filenames. |
|||
- all driver and support classes are using the following naming conventions: |
|||
- class names are in ChamelCase |
|||
- constants are in UPPER_CASE |
|||
- 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) |
|||
- min() definition replaced with std::min() |
|||
- _swap...() definitions replaced with std::swap() |
|||
- String replaced with std::string (No PROGMEM support required with the ESP32) |
|||
|
|||
## Wire class and multi-threading support |
|||
|
|||
A Wire class that mimics the equivalent Arduino class has been added to the library. |
|||
|
|||
Access control to the I2C interface has been added to allow for interrupt based devices access and multi-threading. In the library, all code sequences that require the use of I2C are calling class methods `Wire::enter()` and `Wire::leave()` to reserve and free the interface. |
|||
|
|||
## 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` color 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 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, as supplied through the ESP-IDF framework. All filenames located on the card must be prefixed with `/sdcard/`. |
|||
|
|||
## Image (image.hpp, image.cpp) |
|||
|
|||
- the `drawXXXXFromWeb(WiFiClient *s, ...)` methods are no longer available. WiFiCLient doesn't exists in an ESP-IDF context. |
|||
- 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-6Plus). |
|||
|
|||
Each class that uses the MCPs are independant from each other in terms of initialzing and accessing the MCP. This is the case for EInk, Battery, TouchKeys, Backlight. They all uses `Wire::enter()` and `Wire::leave()` to reserve access to the I2C bus. |
|||
|
|||
## 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. |

Inkplate_Peripheral_Mode sketch for e-radionica.com Inkplate 6 |
|||
Select "Inkplate 6(ESP32)" from Tools -> Board menu. |
|||
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it: |
|||
https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/
|
|||
|
|||
Using this sketch, you don't have to program and control e-paper using Arduino code. |
|||
Instead, you can send UART command (explained in documentation that can be found inside folder of this sketch). |
|||
This give you flexibility that you can use this Inkplate 6 on any platform! |
|||
|
|||
Because it uses UART, it's little bit slower and it's not recommended to send bunch of |
|||
drawPixel command to draw some image. Instead, load bitmaps and pictures on SD card and load image from SD. |
|||
If we missed some function, you can modify this and make yor own. |
|||
Also, every Inkplate comes with this peripheral mode right from the factory. |
|||
|
|||
Learn more about Peripheral Mode in this update: |
|||
https://www.crowdsupply.com/e-radionica/inkplate-6/updates/successfully-funded-also-third-party-master-controllers-and-partial-updates
|
|||
|
|||
UART settings are: 115200 baud, standard parity, ending with "\n\r" (both) |
|||
You can send commands via USB port or by directly connecting to ESP32 TX and RX pins. |
|||
Don't forget you need to send #L(1)* after each command to show it on the display |
|||
(equal to display.display()). |

Inkplate_VariPass_Graphs example for e-radionica Inkplate6 |
|||
For this example you will need a micro USB cable, Inkplate6, and an available WiFi connection. |
|||
Select "Inkplate 6(ESP32)" from Tools -> Board menu. |
|||
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it: |
|||
https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/
|
|||
|
|||
This example will show you how you can use the API on the VariPass website to download and display |
|||
a sensor graph on the e-paper display. |
|||
|
|||
VariPass is a website which allows you to host various online "variables" which you can write to |
|||
and read from using the VariPass API. This allows you to store sensor logs and later retrieve them |
|||
for graphing, analysis, etc. |
|||
This example uses an already public variable as an example. The graph is fed every minute with data |
|||
from Thorinair's (https://github.com/Thorinair/) geiger counter, so each startup of the Inkplate will
|
|||
display updated values. |
|||
|
|||
To learn more about VariPass and how you can use it for your own projects, please visit: https://varipass.org/
|
|||
If you want to easily integrate the read/write functionality in your project, use the official library: |
|||
