The Chromatic’s ESP32 as an SDR: ESP-SDR on the radio side, the FPGA and a RISC-V on the console side, and a USB link to SoapySDR. How the samples move, how the tuning was pushed from the Wi-Fi channels to 1775-2890 MHz, the decoding tools running on the softcore, and what the result can and cannot do.
Our own open AD9361 SDR in an M.2 form factor, built on LiteX. Why we kept the ordinary RFIC, the transports (PCIe, Ethernet, SATA), the White Rabbit timing work, and what’s next.
LiteX was always command-line and text first, for cost reasons. It turns out that’s exactly what an AI agent needs to drive an FPGA. Here’s the methodology we use now, with LiteNVMe and M2SDR as real examples.
