EmanuelFeru 9d6cec8889 Hovercar minor update
- put by default TORQUE mode. Hovercar works best in Torque mode
- made the brake pedal more aggressive. Gives a better braking feel.

EmanuelFeru 72e6b30033 UART with sideboards works + major refactoring
► the mainboard can now send and receive Serial data from the sideboards
► heavy refactored the `main.c`. It was becoming too large to manage... Therefore, `util.c` and `util.h` was created
► added new functionality for `VARIANT_HOVERCAR` and variants with `CONTROL_ADC` in general:
- ADC limits auto-calibration mode (long press of the power button) - calibration will not be lost at power-off
- Max Current and Max Speed adjustment mode (long press followed by a short press of the power button) - calibration will not be lost at power-off
- added one sideboard functionality:
         - LEDs are used to display battery level,  Motor Enable, Errors, Reverse driving, Braking.
         - Photo sensors are used as push buttons: One for changing Control Mode, One for Activating/Deactivating the Field Weakening on the fly

EmanuelFeru b4b23bbe9b Implemented HOVERCAR variant
Major:
- created HOVERCAR variant (selectable via platformio.ini) for driving via 2 pedals: Brake (on cmd1) and Throttle (on cmd2)
- implemented "Double tapping" on Brake pedal to engage Reverse driving
- implemented that Brake pedal stops the vehicle but does not go to Reverse, to prevend unintended Reverse driving
- implemented ADC Protection when GND and Vcc wire are disconnected. The functionality can be enabled/disabled via #define ADC_PROTECT_ENA
- updated error handling: in case of major error the motors will be disabled for improved safety

Minor:
- fixed bug on low-pass filter for not reaching exact "0" value
- calibrated the ADC Battery voltage reading
- other minor visual updates

EmanuelFeru 72d2aae4d7 Made Variant selection easy via platformio.ini
Now it is easy to select between different variant builds via platformio.ini. Currently, 3 variants can be selected:
VARIANT_ADC
VARIANT_USART3
TRANSPOTTER

Note: For any particular needs, you can still change config.h according to your needs.
2019-12-23 12:12:01 +01:00
EmanuelFeru 814af15adc Made beep functions available also for other variants
Beep function "short" and "long" can be used also for other variants than TRASNPOTTER
2019-12-23 10:11:48 +01:00
EmanuelFeru 4c5842915d I prefer that we keep the DEFAULT behavior
Take TRASPOTTER as a firmware variant

EmanuelFeru 0344a9c225 Merge branch 'master' into pr/9 2019-12-14 13:51:37 +01:00
EmanuelFeru 31d42b4a17 Major improvements
- reduced FOC computational complexity by up to 20%, from 85% (old) to 65% (new)
- updated Field Weakening by allowing more freedom set-up: field weakening blended in the input fully, partially blended, or fully outside the input range
- major improvemets on current and speed limitations. It allows seemless limitation protection -> very happy with the result
2019-12-12 23:44:33 +01:00
EmanuelFeru 6c8b7f001d Added Sinusoidal Control Type
Sinusoidal Control Type is now available is this branch. To select it go in config.h and change CTRL_TYP_SEL to 1. By default FOC control type is selcted.
Note: SPEED and TORQUE modes are not available for Sinusoidal control type.
