/* A basic starting point in main.c */
#include <sys/platform.h>
#include "adi_initialize.h"

int main(int argc, char *argv[])
{
	/**
	 * Initialize managed drivers and applications components.
	 */
	adi_initComponents();
	
	/* Begin adding your custom code here */

	return 0;
}

This simple framework allows developers to immediately begin programming the processor.

Practical Code Examples and Applications

2. Open CCES and navigate to File > Import.
3. Select General > Existing Projects into Workspace and click Next.
4. Browse to the directory where the example projects are located.
5. Select the desired project from the list and click Finish.

The project will now appear in the Project Explorer, ready to be built and debugged.

Running a Basic Demo

Running a pre-built demo is an excellent first step. The Audio Loopback TDM example is a perfect choice. After importing and building the project, developers can run it on the hardware. This test confirms that the audio codecs, serial ports, and core processor are functioning correctly. A successful run involves playing audio into the board's input jack and hearing it on the output.

More advanced examples showcase the processor's true power. The FIR Multi Channel Processing demo highlights the dedicated filter accelerator. Recent library optimizations for the SHARC+ core have significantly increased efficiency. Benchmarks show that designs using FIR filters can gain more than 13% processing headroom, freeing the core for other tasks. Running these demos gives developers direct insight into the performance they can expect for demanding DSP applications.

Debugging and Programming the Processor

A robust debugging process is essential for efficient development. It allows developers to find and fix issues within their code. CrossCore® Embedded Studio (CCES) integrates powerful debugging tools. These tools work directly with the EZ-KIT hardware. This enables a seamless workflow from writing code to testing it on the processor. Mastering these tools saves significant time and effort.

Using the On-Board Debug Agent

The EZ-KIT includes an on-board debug agent. This agent acts as the bridge between the developer's PC and the ADSP-21569 processor. CCES communicates through this agent to control code execution and inspect the system. To start a debug session, developers create a launch configuration in the IDE. This configuration tells CCES how to connect to the target board.

Occasionally, CCES may fail to connect. The manual provides troubleshooting steps for these situations. Developers should investigate the following common issues:

1. Check Jumper Settings: Verify the configuration of jumpers like JP1-JP5. Incorrect settings can prevent a connection.
2. Power Cycle the Board: Unplug and replug the power cable after flashing a new program. This resets the board and loads the new image.
3. Try Different RS232 Hardware: Some serial adapters cause issues. An adapter with a reliable FTDI chipset is a good alternative.
4. Verify Port Settings: Ensure the computer's COM port settings match the required configuration.
5. Check for COM Port Interference: Other software can sometimes block the COM port.
6. Inspect Physical Connection: Examine the board's connectors for any physical damage.

Setting Breakpoints and Inspecting Memory

Once connected, developers can use core debugging features. Setting a breakpoint is a fundamental technique. A breakpoint pauses program execution at a specific line of code. In CCES, developers set a breakpoint by clicking in the margin next to a line number.

When the processor hits a breakpoint, the developer can inspect the complete state of the system. This is the most powerful part of the debugging process.

Debugging in Action 🔍: A common task is to inspect an audio buffer in memory. A developer can set a breakpoint after the buffer is filled. They can then open a memory view in CCES to see the raw sample data. This helps verify that the ADC is working and that the data format is correct before it gets processed further.

This capability allows developers to step through code line-by-line, watch variable values change, and pinpoint the exact source of any bugs.
