atse adc25c9b2a pytec: Add hardware testing script 
Eases the process of testing the hardware.

See #143.

atse 9af86be674 pytec: Remove artificial report mode in client 
Encourage polling usage instead, as shown in example.

atse f1da910c11 pytec: Complete client 
Expose all available Thermostat commands to the pytec client, and add
disconnect functionality.

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 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).

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 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.

topquark12 26ad2f0119 rewrite PID 
Rewrite of PID according to https://hackmd.io/IACbwcOTSt6Adj3_F9bKuw PID implementation.

To migrate:
- TEC+/- pin polarity has to be reversed.
- Some saved settings might be wiped upon flashing of new firmware, back up settings before upgrade
- Min / Max integral parameters no longer exist
- kp, ki, kd will likely need to be retuned

The software has been tested on hardware with good temperature control stability.
