| ==== Serial Terminal Output ==== | {{page>/wiki/common#serial_terminal_setup&nofooter&noheader}} |
| | |
| The program outputs data and **CLI** interface to a serial terminal through **UART**. | |
| | |
| - In order to view the data, you must flash the program to the EVAL-ADICUP3029. | |
| - Then follow the UART settings below with the serial terminal program. | |
| | |
| Following is the UART configuration. | |
| Select COM Port | |
| Baud rate: 115200 | |
| Data: 8 bit | |
| Parity: none | |
| Stop: 1 bit | |
| Flow Control: none | |
| \\ | |
| The terminal program must interpret new line as **LF** and **local echo** must be enabled. | |

| ===== Obtaining the Source Code ===== | ===== Obtaining the Software ===== |
| |
| We recommend not opening the project directly, but rather import it into CrossCore Embedded Studios and make a local copy in your workspace. | There are two basic ways to program the ADICUP3029 with the software for the CN0415. |
| | - Dragging and Dropping the .Hex to the Daplink drive |
| | - Building, Compiling, and Debugging using CCES |
| |
| The source code and include files of the **ADuCM3029_demo_cn0415** can be found here: | Using the drag and drop method, the software is going to be a version that Analog Devices creates for testing and evaluation purposes. This is the EASIEST way to get started with the reference design |
| |
| <WRAP round 80% download> | Importing the project into CrossCore is going to allow you to change parameters and customize the software to fit your needs, but will be a bit more advanced and will require you to download the CrossCore toolchain. |
