Homestead Client

A device on your homestead.

Known Problems

• Release builds currently don’t seem to make it past displaying the initial startup message. The problem pertains to the EPD sleep or wake_up.

Getting Started

Get ready to build and flash.

1. Install nightly, the device toolchain, and probe-rs.

rustup toolchain install nightly
rustup override set nightly
rustup target add thumbv6m-none-eabi
cargo install probe-run
cargo install --features=cli probe-rs

1. Download the two Wi-Fi binary blobs from this folder for flashing to the board.

https://github.com/embassy-rs/embassy/tree/main/cyw43-firmware Flash them with `probe-rs` as described below.

probe-rs download --format bin --chip RP2040 --base-address 0x101C0000 43439A0.bin
probe-rs download --format bin --chip RP2040 --base-address 0x101f8400 43439A0_clm.bin

1. Set the following environment variables in .cargo/config.toml
   • WIFI_SSID
   • WIFI_PASSWORD
   • URL is that of the homestead-server (https://github.com/avlec/homestead-server)
2. Good to go. Project can now build via `cargo build` and can run with `cargo run` to flash and get logs from the board.

Debugging performed via `cargo embed`. Programming devices via `cargo flash`.
