* Remove unnecessary duplication of `THERMOSTAT_PARAMETERS`
* i -> ch
* Separate ParameterTree and Parameter initiation
* Remove extra "channel" option to root parameters, as the "value"
option is already the channel number
User input always has the same order of magnitude, so allowing multiple
siPrefixes would be unwanted complexity. Don't allow them to be changed.
The Parameter option "noUnitEditing" is added to do so by the following
measures:
1. Don't validate for changed siPrefix (if pinned) and suffix, which
avoids their removal.
2. Avoid getting the cursor embedded within the unit.
Remove all instances of mA scaling scattered all around the code and
specify it in the parameter tree with a single source of truth.
Done by adding the option "pinSiPrefix" for all Parameters of type `int`
or `float`, and using it for current Parameters with unit "mA".
- Bugs fix:
1. Params Tree user input will not get overwritten
by incoming report thermostat_data_model.
2. PID Autotune Sampling Period is now set according to Thermostat sampling interval
3. PID Autotune won't get stuck in Fail State
4. Various types disconnection related Bugs
5. Number of Samples stored in the plot cannot be set
6. Limit the max settable output current to be 2000mA
- Improvement:
1. Params Tree settings can be changed with external json
2. Use a Tab system to show a single channel of config instead of two
3. Expose PID Autotune lookback params
4. Icon is changed to Artiq logo
- Restructure:
1. Restructure the code to follow Model-View-Delegate Design Pattern
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`
The REF pin of the MAX1968 on hardware revisions v2.x is missing a
buffer, loading the pin on every CPU ADC read. Avoid reading from it and
leave the pin floating on affected hardware revisions, and return the
nominal 1.5V instead.
Thermostats v2.2 and below have a noisy and offset feedback current
`tec_i` caused by missing hardware on 2 MAX1968 TEC driver pins:
1. A missing RC filter on the ITEC pin that would have isolated CPU
sampling pulses from the signal; and
2. Some missing buffering on the VREF pin that would have avoided
loading the VREF signal, preventing voltage drops from the nominal 1.5V.
Since the resulting signal `tec_i` derived from these two signals can
have an error of around +/- 100mA, and readback may affect the stability
performance of the Thermostat, disable current readback entirely on
affected hardware revisions for now.
See https://github.com/sinara-hw/Thermostat/issues/117 and
https://github.com/sinara-hw/Thermostat/issues/120.
On hardware revisions v3.x and above, this would be fixed.
