DPS310 - Pressure 3 click (Mikroe)

Summary

This project shows the implementation of a barometer-sensor driver using Pressure 3 Click (DPS310) from Mikroe integrated with BGM220 Explorer Kit.

Required Hardware

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

• Pressure 3 Click board.

NOTE: Tested boards for working with this example:

Board ID	Description
BRD2703A	EFR32xG24 Explorer Kit - XG24-EK2703A
BRD4314A	BGM220 Bluetooth Module Explorer Kit - BGM220-EK4314A
BRD4108A	EFR32BG22 Explorer Kit Board

Hardware Connection

The Pressure 3 Click board can just be "clicked" into its place. 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 BRD2703A to My Products, click on it, and click on the EXAMPLE PROJECTS & DEMOS tab. Find the example project with filter 'dps310'.

2. Click Create button on the example:

   • Third Party Hardware Drivers - DPS310 - Pressure 3 Click (Mikroe) - I2C if using the I2C interface.

   • Third Party Hardware Drivers - DPS310 - Pressure 3 Click (Mikroe) - SPI if using the SPI interface.

   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_pressure3_dps310/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]
     • [Services] → [IO Stream] → [IO Stream: EUSART] → default instance name: vcom
     • [Application] → [Utility] → [Log]
     • If using the SPI interface:
       • [Third Party Hardware Drivers] → [Sensors] → [DPS310 - Mikroe Pressure 3 Click (SPI)]
       • [Platform] → [Driver] → [SPI] → [SPIDRV] → [mikroe] → change the configuration for [SPI master chip select (CS) control scheme] to "CS controlled by the application"
     • If using the I2C interface:
       • [Third Party Hardware Drivers] → [Sensors] → [DPS310 - Mikroe Pressure 3 Click (I2C)]

4. Install printf float

   • Open Properties of the project.

   • Select C/C++ Build → Settings → Tool Settings → GNU ARM C Linker → General. Check Printf float.

     

5. Build and flash this example to the board.

Note:

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

How It Works

This is an example that demonstrates the use of the Pressure 3 Click board. Measured pressure and temperature data from the DPS310 sensor on the Pressure 3 Click board. Results are being sent to the USART Terminal where you can track their changes. You can launch Console that's integrated into Simplicity Studio or use a third-party terminal tool like TeraTerm to receive the data from the USB. A screenshot of the console output is shown as the figure below.

Report Bugs & Get Support
