# Thermostat v1 prototype firmware
## Building
### On Debian-based systems
- install [rustup](https://rustup.rs/)
```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.
### Commands
| Syntax | Function |
| --- | --- |
| `report` | Show current input |
| `report mode` | Show current report mode |
| `report mode <off/on>` | Set report mode |
| `pwm <0/1> max_i_pos <width> <total>` | Set PWM duty cycle for **max_i_pos** to *width / total* |
| `pwm <0/1> max_i_neg <width> <total>` | Set PWM duty cycle for **max_i_neg** to *width / total* |
| `pwm <0/1> max_v <width> <total>` | Set PWM duty cycle for **max_v** to *width / total* |
| `pwm <0/1> <width> <total>` | Set PWM duty cycle for **i_set** to manual *width / total* |
| `pwm <0/1> pid` | Set PWM to be controlled by PID |
| `pid` | Show PID configuration |
| `pid <0/1> target <value>` | Set the PID controller target |
| `pid <0/1> kp <value>` | Set proportional gain |
| `pid <0/1> ki <value>` | Set integral gain |
| `pid <0/1> kd <value>` | Set differential gain |
| `pid <0/1> output_min <value>` | Set mininum output |
| `pid <0/1> output_max <value>` | Set maximum output |
| `pid <0/1> integral_min <value>` | Set integral lower bound |
| `pid <0/1> integral_max <value>` | Set integral upper bound |
| `s-h` | Show Steinhart-Hart equation parameters |
| `s-h <0/1> <a/b/c> <value>` | Set Steinhart-Hart parameter for a channel |
| `s-h <0/1> parallel_r <value>` | Set parallel resistance of the ADC |
| `postfilter <0/1> rate <rate>` | Set postfilter output data rate |
