Getting Started with the iCEBreaker

To start working with the iCEBreaker FPGA board, follow these steps:

1. Install Open Source Toolchain: Download and set up tools like Yosys, nextpnr, and IceStorm, which are compatible with the iCE40 FPGA.
2. Create a Simple Design: Begin with a basic Verilog or VHDL design. You can start with a simple LED blink example to ensure your setup is working.
3. Synthesize and Place & Route: Use Yosys for synthesis and nextpnr for place and route to convert your code into a design ready to be flashed.
4. Program the FPGA: Use IceStorm or the iCEBreaker’s built-in USB interface to load your bitstream onto the FPGA.
5. Test Your Design: Test the functionality of your design on the board and iterate as needed.

Example Project: Custom Protocol Analyzer

One of the interesting applications of the iCEBreaker is as a protocol analyzer. In this project, the iCEBreaker FPGA can be used to capture and analyze a custom communication protocol:

1. Define Protocol Requirements: Identify the protocol specifications, including clock rate, data format, and timing requirements.
2. Implement the Protocol in Verilog: Write Verilog code to sample and interpret incoming signals according to the protocol’s specifications.
3. Test with Known Signals: Use a signal generator or another device to send signals to the FPGA and verify that your analyzer interprets the protocol correctly.
4. Use Logic Analyzer Software: Connect the output to software tools for visualizing data, aiding in debugging and verifying the protocol’s operation.
