# Title: OLED B Click Board™ ## Description: How Does The OLED B Click Board™ Work? The OLED B Click Board™ as its foundation uses the MI9639BO-B2, a 19.3x7.8mm 96x39px light blue monochrome passive matrix OLED display from Multi-Inno Technology. The MI9639BO-B2 display features an SSD1306, a 128x64 dot-matrix OLED/PLED segment/common driver with a controller. The controller has built-in functionalities like contrast control (256-step brightness control), normal or inverse image display, vertical and horizontal scrolling functions, and much more accessible through the I2C serial interface. OLEDs are emissive and don't require a separate backlight as LCD technology does, reducing the OLED display's overall power consumption compared to LCDs. It also does not suffer from loss of contrast due to bleed-through of the backlight in the "off" pixels. OLEDs, being emissive, have a consistent contrast ratio greater than 100:1 with no limitation in viewing angle. In addition, they don't suffer from temperature-related response time delays and contrast changes. Like any OLED display, the MI9639BO-B2 is made from a thin film of an organic compound that emits light when exposed to a current. A small monochrome display like this one represents an ideal solution for displaying text or icons. The MI9639BO-B2 display is bright, has a wide viewing angle, and low power consumption. In addition to the display's main power supply, taken from the +3.3V microBUS™ power rail, the MI9639BO-B2 has another power pin, more precisely the power supply for DC/DC converter circuit. This pin is the power supply pin for the internal buffer of the DC/DC voltage converter. Therefore, for this pin, the Click board™ uses a low dropout linear regulator AP7331 from Diodes Incorporated, providing a 3.6V power supply out of 5V mikroBUS™ rail. The OLED B Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings. It provides the possibility of the communication-enable feature routed to the CS pin of the mikroBUS™ socket, enabling the OLED B Click for MCU communication only when the CS pin is pulled to a low logic state. In addition, it has two more pins. First is related to the reset function, routed to the RST pin on the mikroBUS™ socket (when the pin is in a low logic state, the initialization of the chip is executed), and the second labelled as D/C and routed to the PWM pin on the mikroBUS™ socket is I2C slave address selection pin. NOTE: If the noise accidentally occurs at the displaying window during the operation, please reset the display to recover the display function. The OLED B Click Board™ is designed to be operated only with a 3.3V logic voltage level, while 5V is used as a supply voltage of the AP7331 LDO. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Small but Bright and Crisp Display

The OLED B Click Board™ features a passive matrix monochrome OLED display featuring small (19.3 x 7.8mm) active display area with a bright and crisp 96 x 39px resolution. The wide viewing angle allows the user to watch your display from any position without losing sight .


.

on-board SSD1306 Controller

SSD1306 is a single-chip CMOS OLED driver that embeds with contrast control, display RAM and oscillator, which reduces the number of external components and power consumption. The controller provides horizontal and vertical scrolling functions, contrast control, normal or inverse image display, and more.

Other OLED Displays

Just like OLED B Click (for blue text), OLED W Click (for white text) is also a member of the monochrome OLED display family. The only difference between these two OLED displays is the colour in which the text is displayed.

Additional Notes and Information

Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

MIKROSDK

The OLED B Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
