Firmware for the Sinara 8451 Thermostat

Building

Debian-based systems (tested on Ubuntu 19.10)

install git, clone this repository
install rustup

rustup toolchain install nightly
rustup update
rustup target add thumbv7em-none-eabihf --toolchain nightly
rustup default nightly
cargo build --release

The resulting ELF file will be located under target/thumbv7em-none-eabihf/release/thermostat

Network

Connecting

Ethernet, IP: 192.168.1.26/24

Use netcat to connect to port 23/tcp (telnet)

nc -vv 192.168.1.26 23

telnet clients send binary data after connect. Enter \n once to invalidate the first line of input.

Reading ADC input

Set report mode to on for a continuous stream of input data.

The scope of this setting is per TCP session.
