MAX6969 - UT-M 7-SEG R Click (Mikroe)

Summary

This project aims to show the hardware driver that is used to interface with the MAX6969 constant-current LED driver via APIs of GSDK.

UT-M 7-SEG R click carries two SMD ultra-thin LED 7-SEG displays and the MAX6969 constant-current LED driver from Analog Devices. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over SPI interface.

Required Hardware

• A BGM220 Explorer Kit board.

• UT-M 7-SEG R Click.

Hardware Connection

The UT-M 7-SEG R Click board supports MikroBus, so it can connect easily to BGM220P Explorer Kit's MikroBus header. Be sure that the board's 45-degree corner matches the Explorer Kit's 45-degree white line.

The hardware connection is shown in the image below:

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 the BRD4314A to My Products, click on it, and click on the EXAMPLE PROJECTS & DEMOS tab. Find the example project with filter max6969

2. Click Create button on the Third Party Hardware Drivers - MAX6969 - UT-M 7-SEG R 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 "BGM220 Explorer Kit Board" using Simplicity Studio v5. Use the default project settings.

2. Copy the file app/example/mikroe_utm7segr_max6969/app.c into the project root folder (overwriting the existing file).

3. Install the software components:

   • Open the .slcp file in the project.

   • Select the SOFTWARE COMPONENTS tab.

   • Install the following components:

     • [Services] → [Timers] → [Sleep Timer]
     • [Third Party Hardware Drivers] → [Display & LED] → [MAX6969 - UT-M 7-SEG R Click (Mikroe)]

4. Build and flash this example to the board.

Note:

• Make sure that the SDK extension already be installed. If not please follow this documentation.

• SDK Extension must be enabled for the project to install "MAX6969 - UT-M 7-SEG R Click (Mikroe)" component.

How It Works

This example demonstrates some of the available features of the 7-Segment LED module. After initialization, the application draws numbers from 0 to 99 on the screen.

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.
