# Firmware for the Sinara 8451 Thermostat
|
|
|
|
- [x] [Continuous Integration](https://nixbld.m-labs.hk/job/stm32/stm32/thermostat)
|
|
- [x] [Download latest firmware build](https://nixbld.m-labs.hk/job/stm32/stm32/thermostat/latest/download-by-type/file/binary-dist)
|
|
|
|
|
|
## Building
|
|
|
|
### Debian-based systems (tested on Ubuntu 19.10)
|
|
|
|
- install git, clone this repository
|
|
- install [rustup](https://rustup.rs/)
|
|
|
|
```shell
|
|
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)
|
|
```sh
|
|
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.
|
|
|
|
|
|
