/* GENERAL NOTES:
* 1. The parameters are over-writing the default motor parameters. For all the available parameters check BLDC_controller_data.c
* 2. The parameters are represented in fixed point data type for a more efficient code execution
* 3. For calibrating the fixed-point parameters use the Fixed-Point Viewer tool (see <https://github.com/EmanuelFeru/FixedPointViewer>)
* 4. For more details regarding the parameters and the working principle of the controller please consult the Simulink model
* 5. A webview was created, so Matlab/Simulink installation is not needed, unless you want to regenerate the code.
* The webview is an html page that can be opened with browsers like: Microsoft Internet Explorer or Microsoft Edge
*
* NOTES Field Weakening / Phase Advance:
* 1. The Field Weakening is a linear interpolation from 0 to FIELD_WEAK_MAX or PHASE_ADV_MAX (depeding if FOC or SIN is selected, respectively)
* 2. The Field Weakening starts engaging at FIELD_WEAK_LO and reaches the maximum value at FIELD_WEAK_HI
* 3. If you re-calibrate the Field Weakening please take all the safety measures! The motors can spin very fast!
Inputs:
- cmd1 and cmd2: analog normalized input values. INPUT_MIN to INPUT_MAX
- button1 and button2: digital input values. 0 or 1
- adc_buffer.l_tx2 and adc_buffer.l_rx2: unfiltered ADC values (you do not need them). 0 to 4095
Outputs:
- speedR and speedL: normal driving INPUT_MIN to INPUT_MAX
