atse e5a8f8b1f8 Stop polling drift 
Just waiting for the update_s doesn't take into account the time to
execute update_params, and causes time drift.

atse b39e7dc015 Finish moving over to qasync 
Also:

* Add aioclient

The old client is synchronous and blocking, and the only way to achieve
true asynchronous IO is to create a new client that interfaces with
asyncio.

* Finish Nix Flake description and make the GUI available for `nix run`

atse 069d791802 Rename all Steinhart-Hart references to B-param 
The Steinhart-Hart equation was changed in code long ago to the
B-parameter equation. Rename references to it and the interface
accordingly. The `s-h` command is now `b-p`.

The reason the name "B-Parameter" equation was chosen over
"Beta-Parameter" was due to its easier searchability.

atse 45eb55d36d steinhart_hart: Beta Parameter uom dimensions 
The Beta Parameter is not dimensionless, and has unit kelvin.
Incorporate that into the type system.

atse f68ae12c8d TCP command: Rename `pwm` to `output` 
Current limit pins are driven by PWM inputs to the MAX1968 driver, but
this is an implementation detail, and should not be exposed in the form
of the command interface. Rename "pwm" to "output" in all instances.

See M-Labs/thermostat#62 (comment).

Show in PwmSummary the set value, before all PWM duty calculations
instead of the machine value after the calculations. Also save the set
value into the flash store instead of the machine value.

atse 5c3b759d0c PwmSummary: Don't show max PWM values 
Putting the maximum in PwmSummary has little use - the maximum never
changes throughout the runtime of the firmware and can be replaced by
documentation elsewhere.

atse 6224486662 Show polarity in pwm command 2024-09-30 17:36:50 +08:00
atse 32bd49b258 Add a command to reverse the output polarity 
Effectively flips all values related to the directionality of current
through the TEC, including current maximums. The reversed status is
stored in the flash store and will be loaded on reset once saved.

The command is "pwm <ch> polarity <normal/reversed>", where the "normal"
polarity is indicated by the front panel markings.

This is needed for IDC cable connections to the Sinara 5432 DAC
"Zotino", since the TEC pins of the 10-pin connector on the Thermostat
and Zotino have opposite polarities.

linuswck ad54842c43 Fix wrong current limit duty cycle calculation 
- prev commit assumed setting 3.3V -> 3A current limit which is wrong

calculation equation

atse b336c4f993 Remove report mode 
As the report mode command breaks the send-receive architecture model of
the command interface, and is deemed an anti-feature, making clients
difficult to write, remove it from the firmware entirely.

* Fix bootloop on some boards.

* Adjust watchdog interval accordingly.

atse 44e9130010 Use oxalica's rust-overlay 
Follow ARTIQ, and in this project lets us include the version number
directly in flake.nix instead of linking to the toml file of a specific
release date, as we use stable Rust.

Also, from nixpkgs manual:
    both oxalica's overlay and fenix better integrate with nix and cache
    optimizations. Because of this and ergonomics, either of those
    community projects should be preferred to the Mozilla's Rust overlay
    (nixpkgs-mozilla).
