nRF51822 Development Tutorial: Getting Started with Bluetooth LE220

Introduction

The nRF51822 is a popular Bluetooth Low Energy (BLE) chip from Nordic Semiconductor. It is designed for low-power applications, such as fitness trackers, medical devices, and smart home devices. This tutorial will provide a step-by-step guide on how to get started with nRF51822 development.

Prerequisites

To follow this tutorial, you will need the following:

* nRF51822 development kit (such as the nRF51 DK)

* Keil µVision IDE (available free from Keil)

* SEGGER J-Link debugger (available free from SEGGER)

Installing Keil µVision and SEGGER J-Link

1. Download and install Keil µVision from the Keil website.

2. Download and install SEGGER J-Link from the SEGGER website.

3. Connect the nRF51 DK to your computer using the USB cable.

Creating a New Project

1. Open Keil µVision.

2. Click on the "File" menu and select "New Project".

3. In the "New Project Wizard", select the "Device" tab.

4. Select "nRF51822" from the list of devices and click "OK".

5. Enter a name for your project and click "Save".

Adding the SEGGER J-Link Debugger

1. Click on the "Project" menu and select "Options for Target".

2. In the "Debugger" tab, select "SEGGER J-Link" from the list of debuggers.

3. Click on the "Settings" button and configure the J-Link settings.

4. Click "OK" to save the settings.

Building and Debugging Your Project

1. Click on the "Build" menu and select "Build Target".

2. If the build is successful, click on the "Debug" menu and select "Start/Stop Debug Session".

3. The J-Link debugger will connect to the nRF51 DK and the Keil µVision IDE will start debugging your code.

Running the Program

1. Click on the "Run" menu and select "Run".

2. The program will start running on the nRF51 DK.

3. You can use the debugger to step through the code and inspect the variables.

Troubleshooting Tips

If you encounter any problems during the development process, here are some troubleshooting tips:

* Make sure that the nRF51 DK is properly connected to your computer.

* Check that the SEGGER J-Link debugger is properly configured.

* Make sure that the Keil µVision IDE is using the correct project settings.

* If you are still having problems, consult the Nordic Semiconductor website for support.

Conclusion

This tutorial has provided a step-by-step guide on how to get started with nRF51822 development. By following these steps, you can create and debug your own BLE applications.
