 # Firmware for the Sinara 8451 Thermostat

- [x] [Download latest firmware build](https://nixbld.m-labs.hk/job/stm32/stm32/thermostat/latest/download-by-type/file/binary-dist)
+- [x] [Continuous Integration](https://nixbld.m-labs.hk/job/mcu/thermostat/thermostat)
+- [x] Download latest firmware build: [ELF](https://nixbld.m-labs.hk/job/mcu/thermostat/thermostat/latest/download/1) [BIN](https://nixbld.m-labs.hk/job/mcu/thermostat/thermostat/latest/download/2)


 ## Building

-### Debian-based systems (tested on Ubuntu 19.10)
+### Reproducible build with Nix

- install git, clone this repository
- install [rustup](https://rustup.rs/)
+Thermostat firmware is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2.4+ and enable flakes by adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (e.g. ``~/.config/nix/nix.conf``). 
+
+Once you have Flakes enabled, you can use ``nix build`` to build the firmware.
+
+### Development environment
+
+Clone this repository and with Nix Flakes enabled, use the following commands:

 ```shell
-rustup toolchain install nightly
-rustup update
-rustup target add thumbv7em-none-eabihf --toolchain nightly
-rustup default nightly
+nix develop
 cargo build --release
 ```

-The resulting ELF file will be located under `target/thumbv7em-none-eabihf/release/thermostat`
+The resulting ELF file will be located under `target/thumbv7em-none-eabihf/release/thermostat`.

+Alternatively, you can install the Rust toolchain without Nix using rustup; see the `rust` variable in `flake.nix` to determine which Rust version to use.

-## Network
+## Debugging
+
+Connect SWDIO/SWCLK/RST/GND to a programmer such as ST-Link v2.1. Run OpenOCD:
+```shell
+openocd -f interface/stlink.cfg -f target/stm32f4x.cfg
+```
+
+You may need to power up the programmer before powering the device.
+Leave OpenOCD running. Run the GNU debugger:
+```shell
+gdb target/thumbv7em-none-eabihf/release/thermostat
+
+(gdb) source openocd.gdb
+```
+
+## Flashing
+There are several options for flashing Thermostat. DFU requires only a micro-USB connector, whereas OpenOCD needs a JTAG/SWD adapter.
+
+### dfu-util on Linux
+* Install the DFU USB tool (dfu-util).
+* Convert firmware from ELF to BIN: `llvm-objcopy -O binary target/thumbv7em-none-eabihf/release/thermostat thermostat.bin` (you can skip this step if using the BIN from Hydra)
+* Connect to the Micro USB connector to Thermostat below the RJ45.
+* Add jumper to Thermostat v2.0 across 2-pin jumper adjacent to JTAG connector.
+* Cycle board power to put it in DFU update mode
+* Push firmware to flash: `dfu-util -a 0 -s 0x08000000:leave -D thermostat.bin`
+* Remove jumper
+* Cycle power to leave DFU update mode
+
+### st.com DfuSe tool on Windows
+On a Windows machine install [st.com](https://st.com) DfuSe USB device firmware upgrade (DFU) software. [link](https://www.st.com/en/development-tools/stsw-stm32080.html).
+- add jumper to Thermostat v2.0 across 2-pin jumper adjacent to JTAG connector
+- cycle board power to put it in DFU update mode
+- connect micro-USB to PC
+- use st.com software to upload firmware
+- remove jumper
+- cycle power to leave DFU update mode
+
+### OpenOCD
+```shell
+openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c "program target/thumbv7em-none-eabihf/release/thermostat verify reset;exit"
+```
+
+## GUI Usage
+
+The Thermostat Control Panel is available for easy configuration and plotting of key parameters.
+It is included in the enclosed PyThermostat library, developed based on the Python libraries PyQt and PyQtGraph.
+
+Launch it by either running:
+
+```sh
+nix run git+https://git.m-labs.hk/M-Labs/thermostat#control_panel
+```
+
+Or, without Nix, run it after installing the PyThermostat library:
+
+```sh
+pip install git+https://git.m-labs.hk/M-Labs/thermostat#subdirectory=pythermostat
+thermostat_control_panel
+```

+
+## USB
+
+The firmware includes experimental support for acting as a USB-Serial
+peripheral. Debug logging will be sent there by default (unless build
+with logging via semihosting.)
+
+**Caveat:** This logging does not flush its output. Doing so would
+hang indefinitely if the output is not read by the USB host. Therefore
+output will be truncated when USB buffers are full.
+
+
+## Temperature measurement
+
+Connect the thermistor with the SENS pins of the
+device. Temperature-depending resistance is measured by the AD7172
+ADC. To prepare conversion to a temperature, set the parameters
+for the B-Parameter equation.
+
+Set the base temperature in degrees celsius for the channel 0 thermistor:
+```
+b-p 0 t0 20
+```
+
+Set the resistance in Ohms measured at the base temperature t0:
+```
+b-p 0 r0 10000
+```
+
+Set the Beta parameter:
+```
+b-p 0 b 3800
+```
+
+### 50/60 Hz filtering
+
+The AD7172-2 ADC on the SENS inputs supports simultaneous rejection of
+50 Hz ± 1 Hz and 60 Hz ± 1 Hz (dB). Affecting sampling rate, the
+postfilter rate can be tuned with the `postfilter` command.
+
+| Postfilter rate | Rejection | Effective sampling rate |
+| ---             | :---:     | ---                     |
+| 16.667 Hz       | 90 dB     | 8.4 Hz                  |
+| 20 Hz           | 85 dB     | 9.1 Hz                  |
+| 25 Hz           | 62 dB     | 10 Hz                   |
+| 27.27 Hz        | 47 dB     | 10.41 Hz                |
+
+## Thermo-Electric Cooling (TEC)
+
+- Connect TEC module device 0 to TEC0- and TEC0+.
+- Connect TEC module device 1 to TEC1- and TEC1+.
+- The GND pin is for shielding not for sinking TEC module currents.
+
+When using a TEC module with the Thermostat, the Thermostat expects the thermal load (where the thermistor is located) to cool down with a positive software current set point, and heat up with a negative current set point.
+
+If the Thermostat is used for temperature control with the Sinara 5432 DAC "Zotino", and is connected via an IDC cable, the TEC polarity may need to be reversed with the `output <ch> polarity reversed` TCP command.
+
+Testing heat flow direction with a low set current is recommended before installation of the TEC module.
+
+### Limits
+
+Each channel has maximum value settings, for setting
+output limits.
+
+Use the `output` command to see them.
+
+| Limit       | Unit    | Description                   |
+| ---         | :---:   | ---                           |
+| `max_v`     | Volts   | Maximum voltage               |
+| `max_i_pos` | Amperes | Maximum positive current      |
+| `max_i_neg` | Amperes | Maximum negative current      |
+
+Example: set the maximum voltage of channel 0 to 1.5 V.
+```
+output 0 max_v 1.5
+```
+
+Example: set the maximum negative current of channel 0 to -2 A.
+```
+output 0 max_i_neg 2
+```
+
+Example: set the maximum positive current of channel 1 to 2 A.
+```
+output 1 max_i_pos 2
+```
+
+### Open-loop mode
+
+To manually control TEC output current, set a fixed output current with
+the `output` command. Doing so will disengage the PID control for that
+channel.
+
+Example: set output current of channel 0 to 0 A.
+```
+output 0 i_set 0
+```
+
+## PID-stabilized temperature control
+
+Set the target temperature of channel 0 to 20 degrees celsius:
+```
+pid 0 target 20
+```
+
+Enter closed-loop mode by switching control of the TEC output current
+of channel 0 to the PID algorithm:
+```
+output 0 pid
+```
+
+### PID output clamping
+
+It is possible to clamp the PID algorithm output independently of channel output limits. This is desirable when e.g. there is a need to keep the current value above a certain threshold in closed-loop mode.
+
+Note that the actual output will still ultimately be limited by the `max_i_pos` and `max_i_neg` values.
+
+Set PID maximum output of channel 0 to 1.5 A.
+```
+pid 0 output_max 1.5
+```
+
+Set PID minimum output of channel 0 to 0.1 A.
+```
+pid 0 output_min 0.1
+```
+

+| L4   | Green | Firmware busy                  |
+
+## Reports
+
+Use the bare `report` command to obtain a single report. Reports are JSON objects
+with the following keys.
+
+| Key            | Unit            | Description                                          |
+| ---            | :---:           | ---                                                  |
+| `channel`      | Integer         | Channel `0`, or `1`                                  |
+| `time`         | Seconds         | Temperature measurement time                         |
+| `interval`     | Seconds         | Time elapsed since last report update on channel     |
+| `adc`          | Volts           | AD7172 input                                         |
+| `sens`         | Ohms            | Thermistor resistance derived from `adc`             |
+| `temperature`  | Degrees Celsius | B-Parameter conversion result derived from `sens`    |
+| `pid_engaged`  | Boolean         | `true` if in closed-loop mode                        |
+| `i_set`        | Amperes         | TEC output current                                   |
+| `dac_value`    | Volts           | AD5680 output derived from `i_set`                   |
+| `dac_feedback` | Volts           | ADC measurement of the AD5680 output                 |
+| `i_tec`        | Volts           | MAX1968 TEC current monitor                          |
+| `tec_i`        | Amperes         | TEC output current feedback derived from `i_tec`     |
+| `tec_u_meas`   | Volts           | Measurement of the voltage across the TEC            |
+| `pid_output`   | Amperes         | PID control output                                   |
+
+Note: Prior to Thermostat hardware revision v2.2.4, the voltage and current readouts `i_tec` and `tec_i` are noisy without the hardware fix shown in [this PR](https://git.m-labs.hk/M-Labs/thermostat/pulls/105).
+
+## PID Tuning
+
+The thermostat implements a PID control loop for each of the TEC channels, more details on setting up the PID control loop can be found [here](./doc/PID%20tuning.md).
+
+## Fan control
+
+Fan control commands are available for thermostat revisions with an integrated fan system:
+1. `fan` - show fan stats: `fan_pwm`, `abs_max_tec_i`, `auto_mode`, `k_a`, `k_b`, `k_c`.
+2. `fan auto` - enable auto speed controller mode, where fan speed is controlled by the fan curve `fcurve`.
+3. `fan <value>` - set the fan power with the value from `1` to `100` and disable auto mode. There is no way to completely disable the fan.
+Please note that power doesn't correlate with the actual speed linearly.
+4. `fcurve <a> <b> <c>` - set coefficients of the controlling curve `a*x^2 + b*x + c`, where `x` is `abs_max_tec_i/MAX_TEC_I`, a normalized value in range [0,1],
+i.e. the (linear) proportion of current output capacity used, on the channel with the largest current flow. The controlling curve is also clamped to [0,1].
+5. `fcurve default` - restore fan curve coefficients to defaults: `a = 1.0, b = 0.0, c = 0.0`.

+# PID Tuning
+
+## Note on hardware setup
+
+The heat sinking side of the TEC module should be thermally bonded to a large heat-sinking thermal mass to ensure maximum temperature stability, a large optical table had provided good results in tests.
+
+The thermal load under control should be well insulated from the surrounding for maximum stability, closed cell foam had been tested showing good results.
+
+## Real time plot
+
+When tuning Thermostat PID parameters, it is helpful to view the temperature, PID output and other data in the form of a real time graph.
+
+To use the Python real-time plotting utility, run
+
+```shell
+python pythermostat/pythermostat/plot.py
+```
+
+![default view](./assets/default%20view.png)
+
+## Temperature Setpoints and Thermal Load
+
+A PID controller with the same set of PID parameters may not work identically across all temperatures, especially when comparing the performance of a TEC module cooling a load versus heating a load. This is due to self ohmic heating of the TEC module aiding efficiency when  heating, but harming efficiency when cooling.
+
+When a PID loop is expected to operate the TEC in both heating and cooling modes, it is important to verify the loop performance in both modes.
+
+For systems expected to operate at a narrow range of temperatures, it is a good idea to tune the PID loop at the temperature region of interest.
+
+The same is also true for controlling loads that are expected to produce heat, e.g. laser cooling blocks. Testing the loop performance across varying amount of thermal load is needed to ensure stability in operation.
+
+## Manual Tuning
+
+Below are some general guidelines for manually tuning PID loops. Note that every system is different, and some of the values mentioned below may not apply to all systems.
+
+1. To start the manual tuning process, set the kp, ki and kd parameters to 0.
+
+2. Begin by increasing kp until the temperature begins to oscillate. Offset between the target temperature and the actual temperature can be ignored for now.
+
+3. Reduce kp by 30%, increase ki until the offset between target and actual temperature is eliminated.
+
+4. Increase kd until the maximum allowable amount of overshoot is observed.
+
+5. Some tweaking will be needed to obtain the desired result, especially when trying to balance between minimizing overshoot and maximizing response speed.
+
+## Auto Tuning
+
+A PID auto tuning utility is provided in the PyThermostat library. The auto tuning utility drives the the load to a controlled oscillation, observes the ultimate gain and oscillation period and calculates a set of PID parameters.
+
+To run the auto tuning utility, run
+
+```shell
+python pythermostat/pythermostat/autotune.py
+```
+
+After some time, the auto tuning utility will output the auto tuning results, below is a sample output
+
+```shell
+Ku: 0.7553203471147422
+Pu: 75.93899999999977
+rule: ziegler-nichols
+kp: 0.45319220826884526
+Ki: 0.011935690706194357
+Kd: 4.301870387965967
+rule: tyreus-luyben
+kp: 0.3432930977636503
+Ki: 0.0020549280832497956
+Kd: 4.137825730504864
+        .
+        .   
+        .
+```
+
+At the end of the test, the ultimate gain `Ku`, oscillation period `Pu` and a few sets of recommended PID parameters are calculated and displayed.  
+
+Multiple suggested sets of PID parameters based on different calculation rules are displayed. While all sets are expected to work, the different sets trade off response time with overshoot differently, and testing is needed to see which set works best for the system on hand.
+
+With a well designed and constructed setup, the PID parameters calculated by the auto tune utility together with some manual tweaking can yield sub-mK control stability.
+
+Below shows data captured on an experiment setup, with 300uK stability over 12 hours.
