# Thermostat v1 prototype firmware
|
|
|
|
## Building
|
|
|
|
### On Debian-based systems
|
|
|
|
- install rustup
|
|
|
|
```shell
|
|
apt install gcc gcc-arm-none-eabi git-core
|
|
rustup toolchain install nightly
|
|
rustup update
|
|
rustup target add thumbv7em-none-eabihf --toolchain nightly
|
|
rustup default nightly
|
|
rustup component add rust-src
|
|
cargo install cargo-xbuild
|
|
git clone https://github.com/llvm/llvm-project.git
|
|
export RUST_COMPILER_RT_ROOT=`pwd`/llvm-project/compiler-rt
|
|
|
|
cd firmware && cargo xbuild --release
|
|
```
|
|
|
|
The built ELF file will be at `target/thumbv7em-none-eabihf/release/ionpak-firmware`
|
|
|
|
### Development build on NixOS
|
|
|
|
Requires NixOS 19.09 or later for cargo-xbuild.
|
|
|
|
```shell
|
|
nix-shell --run "cd firmware && cargo xbuild --release"
|
|
```
|
|
|
|
## Network
|
|
|
|
### Setup
|
|
|
|
Ethernet, IP: 192.168.1.26/24
|
|
|
|
Use telnet or netcat to connect to port 23/tcp (telnet)
|
|
|
|
### Reading ADC input
|
|
|
|
Set report mode to `once` to obtain the single next value. Report mode
|
|
will turn itself off after the next reading.
|
|
|
|
Set report mode to `continuous` for a continuous stream of input data.
|
|
|
|
The scope of this setting is per TCP session.
