It can be used in designing a control panel for an industrial machine… or a DIY arcade. Features and usage notes Hardware: a full color OLED built in a button This board has a module that combines a button and a full color organic LED display, plus input/output screw terminals for connecting external electronics. The mechanical button itself is nicely built, with a translucent black housing. When pressed, it gives satisfying tactile feedback. The display, built in the button itself, can show 64 by 48 pixel images with up to 65k colors (16-bit depth). With the screw terminals, you can toggle an external circuit on and off. The display is big enough to display simple information, whether as icons or words. Small characters are legible and clear. The most interesting feature is that the display can be programmed to change the picture when needed (for example, you can design a reprogrammable keypad that would allow users to switch from latin to cyrillic script or to chinese characters). VisualTFT can be used to prepare the bmp images. There is a learn.mikroe.com article that explains how to to take 16 or 24 bit bmp pictures and create C arrays. OLED Switch click 2 The board communicates with the target MCU through the mikroBUS™ SPI interface. It uses a 3.3V power supply only. Software: frame buffering The internal frame buffer on the OLED display holds 96x64 pixels with 2 bytes of 565 formatted color information for each. When displaying an image the size of the display, (64x48) the image will be displayed well, unless scrolled. To scroll an image without having random pixels from unused space in the internal frame buffer, load a 96x64 image onto the OLED Switch click with your desired image centered like the blue colored area in the picture below. Programming This code snippet takes a 565 formatted 16-bit bitmap and displays it on the OLED display, and then scrolls the image across the display. #define BIG_IMG_SIZE 12288 void main() { //Local Declarations scroll_t scroll; scroll.col_horiz_shift scroll.row_offset scroll.row_horiz_shift doesn't work well, because scroll.row_vert_shift scroll.interval //Used for scroll settings = 0x01; //Shift left to right = 0; //No offset of rows = 64; //64: BIG IMAGE, 47:SMALL ( SMALL of firmware on click side ) = 0; //No vertical shifting = 1; //1: 10 frames between each shift //Setup system_setup( BIG ); //Provide size of allocated space for images ( 64x48 or 96x64 ) OLED Switch click 3 oled_switch_deactivate_scrolling(); //Scrolling must be absolutely deactivated first oled_switch_scrolling_setup( scroll ); //Next, setup scroll settings oled_switch_draw_565_img( oled_switch_logo_big_bmp, BIG_IMG_SIZE ); //Draw the image to scroll oled_switch_activate_scrolling(); //Activate scrolling on screen while( 1 )//Forever { } } Code examples for OLED Switch click, written for MikroElektronika hardware and compilers are available on Libstock [4].
