* Dual CC1101 sub-GHz lab instrument (fixed carriers + optional capture/replay).
|
|
* ESP32-S3 DevKitC-1: two CC1101 on shared SPI.
|
|
* Radio 1: 315.0 MHz narrow FM + LFSR on GDO0; Radio 2: 433.92 MHz wide FM + LFSR.
|
|
* Intended for authorized RF research (e.g. sealed anechoic / shielded chamber).
|
|
* CC1101 reset and SPI sequencing follow TI SWRS061 (CHIP_RDYn, SRES Fig. 27).
