Pico-Backscatter

An educational project on backscatter using Raspberry Pi Pico

Repo Organization

• hardware contains the hardware design with further description and explanation (generating the PIO using the python script).
• project_pico_libs contains the libs for all projects using the RPI Pico (carrier/receiver/baseband).
• baseband contains a 2-FSK baseband code using Pico PIO together with a generator script, its description and some exercise questions.
• carrier-CC2500 contains a carrier generator using the Mikroe-1435 (CC2500) on the Pico.
• receiver-CC2500 contains a receiver using the Mikroe-1435 (CC2500) on the Pico.
• carrier-Firefly contains the configuration guidance for home setup with zolertia firefly as carrier.
• carrier-characteristics contains a measurement to estimate the typical carrier bandwidth.
• carrier_receiver-CC1352 contains the configuration guidance for lab setup with CC1352 as carrier and/or receiver.
• carrier-receiver-baseband integrates all components into one setup: the Pico generates the baseband, uses one Mikroe-1435 (CC2500) to generate a carrier and a second Mikroe-1435 (CC2500) to receive the backscattered signal.
• stats contains the system evaluation script.

Installation

A number of pre-requisites are needed to work with this repo: Raspberry Pi Pico SDK, cmake and arm-none-eabi-gcc have to be installed for building and flashing the application code.
Please follow the installation guidance in Getting started with Rasberry Pi Pico.
Using Visual Studio Code is recommended.
