- 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.
Put SocketState initialisation logic in new. This avoids using an unsafe
and unnerving MaybeUninit::uninit().assume_init() to initialise an
array, which the compiler yells at since it causes undefined behavior.
Since VREF is an implementation detail, there shouldn't be a need to
include it in reports.
The ChannelState vref is removed along with it as its only use was to
save VREF measurements for later reporting.
Change the behaviour of LED L3 to turn off only when all channels have
PID disengaged, as opposed to when any channel disengages PID.
Otherwise, when disengaging PID on a Thermostat that has had both
channels engaged in PID, the LED would turn off, even when PID is still
engaged on the other channel.
This lets the LED better reflect the status of the Thermostat as a
whole, as it would stay on as long as PID is engaged on at least one
channel.
