|

|

### dfu-util on Linux
|
||||
* Install the DFU USB tool (dfu-util).
|
||||
* Convert firmware from ELF to BIN: `arm-none-eabi-objcopy -O binary target/thumbv7em-none-eabihf/release/thermostat thermostat.bin` (you can skip this step if using the BIN from Hydra)
|
||||
* Convert firmware from ELF to BIN: `arm-none-eabi-objcopy -O binary 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

## Fan control
|
||||
|
||||
Fan control commands are available for thermostat revisions with an integrated fan system:
|
||||
1. `fan` - show fan stats: `fan_pwm`, `max_abs_i_measured`, `auto_mode`, `k_a`, `k_b`, `k_c`.
|
||||
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 `max_abs_i_measured/MAX_I`, a normalized value in range [0,1],
|
||||
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`.
