使用eINK显示屏和STM32F031K6创造、指挥和创新如从未有过

 * \brief Eink Click example
 * 
 * # Description
 * This application demonstrates the use of eINK Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and configures the Click board for 2.00 inch eINK display.
 * After that, if the TEXT mode is supported, shows a desired text messages on the display.
 * 
 * ## Application Task  
 * Draws two demo images to the display with a one-second delay between each drawing.
 *  
 * @note 
 * Due to insuficient RAM memory, only the IMAGE mode is supported with 8-bit PIC microcontrollers.
 * 
 * Here is the procedure for creating an Image or Font arrays:
 * 
 * - Create Image:
 *    Save the image in resolution of 172x72 px with the extension (jpg) ...
 *    Upload the image to Image2Lcd program
 *    Set parameters to:
 *           1. Output file type : C array
 *           2. Scan Mode : Vertical scan
 *           3. Bits Pixel : 4 Color
 *           4. Max Width and Height : 172x72
 *           5. Select only MSB first checkmark
 *           6. Check Reverse color and adjust Normal type
 *    The image to be generated should contain exact 3096 bytes ...
 *    Insert the image into the file eink_display_image.h
 * 
 * - Create Font:
 *    Create a new VisualTFT project
 *    Add label and adjust text font
 *    Generate source code
 *    Copy the font array from resource.c file and paste it to eink200inch_font.h file
 * 
 * *** Changing the LUT table can lead to loss of display performance ....
