PI controller update and fixes Major: • all PI controllers with Back-calculation replaced with PI controllers with Clamping to reduce the number of parameters and simplify calculations Minor: • fixed the ADC calibration for potetiometer input when ADCx_MIN > 0 • fixed bug: small shock at initialization when current limit I_MOT_MAX is set very small e.g. 1 A

Floating-point converted to fixed-point The follwing were converted to fixed-point - battery voltage - board temperature - filters for steer and speed - mixer calculation Starting from this moment, the firmware is floating point free, meaning it runs more efficiently.
2019-10-20 11:31:47 +00:00
/* GENERAL NOTES:
* 1. The above 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

* 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!

Improvements and Issues implementation Major: - Issue #3: added raw ADC1, ADC2 values to the setScopeChannel - Issue #4: added functionality for joystick control. Middle resting potis are now supported (by default it is enabled) - Issue #6: implemented that board does not power-off after a software reset due to flashing - added Rate constraints for Input target for smoother response Minor: - added 2 beep sound when motors get enabled - minor bugfixes
