LD2410S: investigating radar buses and firmware

The LD2410S investigation documents the I2C and SPI traffic between a Hi-Link FMCW radar board's components and examines its Puya controller firmware. It includes Saleae captures, oscilloscope images, an interpreted Range FFT frame, firmware strings and an interrupt vector map. The author labels the investigation as work in progress.
