SSD1306 - Mikroe OLEDW Click (Mikroe)

Summary

This project shows the driver implementation of a SPI OLED using the SSD1306 IC with Silicon Labs Platform.

MikroE OLED W Click is based on the MI9639BO-W OLED module which has a size of 19.3x7.8 mm and resolution of 96x39 pixels. This white light monochrome, passive matrix OLED display is from Multi-Inno Technology. The MI9639BO-W display features an SSD1306 device that is a 128x64 pixel, dot-matrix OLED/PLED segment/common driver with a controller. It can be used for applications where bright and crisp white text or icons are needed.

Required Hardware

• BGM220-EK4314A BGM220 Bluetooth Module Explorer Kit (BRD4314A BGM220 Explorer Kit Board)

• Or SiWx917 Wi-Fi 6 and Bluetooth LE 8 MB Flash SoC Pro Kit (BRD4002 + BRD4338A)

• OLED W Click board based on SSD1306 IC

Hardware Connection

• If the BGM220P Explorer Kit is used:

  The OLEDW Click board supports MikroBus, so it can connect easily to the Explorer Kit via MikroBus header. Assure that the 45-degree corner of Click board matches the 45-degree white line of the Explorer Kit.

  The hardware connection is shown in the image below:

  

• If the SiWx917 Wi-Fi 6 and Bluetooth LE 8 MB Flash SoC Pro Kit is used:

  Description	BRD4338A GPIO	BRD4002 Breakout Pad	OLED W click
  RESET	GPIO_46	P24	RST
  DATA/COMMAND	GPIO_47	P26	D/C
  RTE_GSPI_MASTER_CLK_PIN	GPIO_25	P25	SCK
  RTE_GSPI_MASTER_MOSI_PIN	GPIO_27	P29	SDI
  RTE_GSPI_MASTER_CS0_PIN	GPIO_28	P31	CS

Setup

You can either create a project based on an example project or start with an empty example project.

Create a project based on an example project

1. From the Launcher Home, add your device to My Products, click on it, and click on the EXAMPLE PROJECTS & DEMOS tab. Find the example project filtering by oledw.

2. Click Create button on the Third Party Hardware Drivers - SSD1306 - Mikroe OLEDW Click (Mikroe) example. Example project creation dialog pops up -> click Create and Finish and Project should be generated.

   

3. Build and flash this example to the board.

Start with an empty example project

1. Create an "Empty C Project" for the your board using Simplicity Studio v5. Use the default project settings.

2. Copy the file app/example/mikroe_oledw_ssd1306/app.c into the project root folder (overwriting existing file).

3. Install the software components:

   • Open the .slcp file in the project.

   • Select the SOFTWARE COMPONENTS tab.

   • Install the following components:

     If the BGM220P Explorer Kit is used:

     • [Services] → [Timers] → [Sleep Timer]
     • [Application] → [Utility] → [Assert]
     • [Third Party Hardware Drivers] → [Display & LED] → [SSD1306 - OLED W Click (Mikroe) - SPI] → use default configuration

     If the SiWx917 Wi-Fi 6 and Bluetooth LE 8 MB Flash SoC Pro Kit is used:

     • [WiSeConnect 3 SDK] → [Device] → [Si91x] → [MCU] → [Service] → [Sleep Timer for Si91x]
     • [Application] → [Utility] → [Assert]
     • [Third Party Hardware Drivers] → [Display & LED] → [SSD1306 - OLED W Click (Mikroe) - SPI] → use default configuration

4. Build and flash this example to the board.

Note:

• Make sure that the Third Party Hardware Drivers extension is installed. If not, follow this documentation.

• SDK Extension must be enabled for the project to install "SSD1306 - OLED W Click (Mikroe) - SPI" component.

How It Works

The OLED display will look something like the GIF below.

Report Bugs & Get Support

To report bugs in the Application Examples projects, please create a new "Issue" in the "Issues" section of third_party_hw_drivers_extension repo. Please reference the board, project, and source files associated with the bug, and reference line numbers. If you are proposing a fix, also include information on the proposed fix. Since these examples are provided as-is, there is no guarantee that these examples will be updated to fix these issues.
