EmanuelFeru 083088724e Updated mainboard picture 2020-05-26 22:49:12 +02:00
EmanuelFeru 736f2b9419 Minor updates
- updated ReadMe: added higher resolution mainboard picture, added links with projects, online compiler, Telegram link
- setup.c : fixed the Charger GPIO pin to PULLUP, otherwise the Charger won't be recognized when connected
- config.h : increased the default ADC protection Timeout from 30 to 100 for more robustness.

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 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

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.

EmanuelFeru 9a9eed7d10 Updated current limit
The firmware allows now to set higher currents than 15 A/motor.
NOTE: You can change this limit at your own risk. I do not take any responsability if your boards gets damaged.

EmanuelFeru 62873aad57 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

EmanuelFeru af14b3c4b1 Improved Field Weakening
The performance of the Field Weakening is improved by reducing noise at higher speeds.
