// Triggered by host opcode 0x30. Exercises each subsystem independently:
|
||||
// Test 0: BRAM write/read pattern (walking 1s)
|
||||
// Test 1: CIC impulse response check (known input → expected output)
|
||||
// Test 2: FFT known-input test (DC input → bin 0 peak)
|
||||
// Test 3: Arithmetic / saturating-add check
|
||||
// Test 4: ADC raw data capture (dump N samples to host)
|
||||
//
|
||||
// Results reported back via a status register readable by host (opcode 0x31).
|
||||
// Each test produces a PASS/FAIL bit in result_flags[4:0].

//
|
||||
// Integration: radar_system_top.v wires host_self_test_trigger (from opcode 0x30)

// to this module's `trigger` input, and reads `result_flags` / `result_valid`
|

// via opcode 0x31.

AERIS-10 Radar Dashboard — Board Bring-Up Edition
|
||||
===================================================
|
||||
Real-time visualization and control for the AERIS-10 phased-array radar
|
||||
via FT601 USB 3.0 interface.
|
||||
|
||||
Features:
|
||||
- FT601 USB reader with packet parsing (matches usb_data_interface.v)
|
||||
- Real-time range-Doppler magnitude heatmap (64x32)
|
||||
- CFAR detection overlay (flagged cells highlighted)
|
||||
- Range profile waterfall plot (range vs. time)
|
||||
- Host command sender (opcodes 0x01-0x27, 0x30, 0xFF)
|
||||
- Configuration panel for all radar parameters
|
||||
- HDF5 data recording for offline analysis
|
||||
- Mock mode for development/testing without hardware
|
||||
|
||||
Usage:
|
||||
python radar_dashboard.py # Launch with mock data
|
||||
python radar_dashboard.py --live # Launch with FT601 hardware
|
