What can You do With the Cypress Bluetooth Mesh Development Kit?Ok, those specs sound great, but what can you actually do with this Cypress Bluetooth SoC (system on a chip)? With the range of maker boards and MCUs available, there's a host of different use cases. The CYW902819EVB-02 posits itself as a board suitable for embedded devices. For instance, it's perfect for wearables like fitness bands. Since mesh networking is incredibly popular in smart home networking, this is a great board for smart home automation and smart home control.
Likewise, with a slew of sensors onboard, it's excellent for proximity sensors, as well as medical applications, a space where IoT has become increasingly popular. For instance, the Cypress Bluetooth development kit functions for medical IoT devices such as blood pressure monitors. Similarly, its extensive Bluetooth offerings mean it's capable of audio applications such as wireless headphones or Bluetooth audio dongles. The possibilities are nearly limitless.
What can you use the CYW902819EVB-02 and CYW20189 for:
- Smart home automation and control i.e. thermostats
- Bluetooth audio i.e. headphones
- IoT medical applications i.e. blood pressure monitors
- Sensor data capture
Getting Started with the CYW20819 and CYW920819EVB-02
How to use the CYW902819EVB-02 is pretty simple. This Bluetooth MCU device is intuitive. You'll need a compatible device, plus the ModusToolbox. First, download and install the ModusToolbox. When that's finished, fire it up. With ModusToolbox installed, you can launch the quick start guide with Help > ModusToolbox IDE DOcumentation > Quick Start Guide or open the user guide for a more comprehensive overview with Help > ModusToolbox IDE Documentation > User Guide.
Based on the Eclipse IDE Oxygen iteration, ModusToolbox iDE features a bevy of plugins such as an Eclipse C/C++ Development Tools (CDT) plugin. In ModusToolbox, you can spin up new apps with starter apps based on devices and kits, plus utilize a conglomeration of online code examples at your fingertips.
To create a new application, first select a new workspace. You can select an existing empty directory with Browse or type a directory name for use. Then, navigate to File > New > ModusToolbox IDE Application to create a new app. Alternatively, under the quick launch menu, click New Application. Then, choose your hardware. For a Cypress board, hit Dev/Eval Kit, in this case the CYW902819EVB-02. Or, if you're using a board based on the CYW20819, pick Custom Hardware, then hit Next and the correct board from the list.
With your board selected, you can select a starter application. There's a list of different apps you can import along with descriptions. For instance, NewPioneer will perform some basic set up for the PSoC 6 kit and configure the likes of clocks and UART. Once you've selected a starter app, hit Next, and then you'll see a synopsis of the app. Click Finish, and the application is created which you'll see in the IDE. This really simplifies development for the CYW902818EVB-02 eval kit.
