Added inertia simulation for compass heading:
In previous version calculated compass values were directly used for visualization of the compass. This causes a fast changing (jumping) of values. With the inertia introduction the compass behalfs more like an analog compass. The final value is reached slowly and the displayed values are more stable.
For configuration a new menu item has been added to the compass menu allowing to switch inertia off (default), small and large inertia simulation

This output is an open-drain NMOS device that is rated to 20 V. The open-drain FET connected to the CHG pin will be turned on whenever the output (BAT) of the charger is enabled. As a note, the output of the charger supply will not be enabled if the VRECT-REG does not converge to the no-load target voltage. CHG F4 7 O Open-drain output – active when BAT is enabled. Float if not used. @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2015 heinrichs weikamp</center></h2> * ****************************************************************************** */ /* Includes ------------------------------------------------------------------*/ #include "batteryCharger.h" #include "batteryGasGauge.h" #include "stm32f4xx_hal.h" #include "scheduler.h" #define CHARGE_IN_PIN GPIO_PIN_2 #define CHARGE_IN_GPIO_PORT GPIOC #define CHARGE_IN_GPIO_ENABLE() __GPIOC_CLK_ENABLE() #define CHARGE_OUT_PIN GPIO_PIN_1 #define CHARGE_OUT_GPIO_PORT GPIOC #define CHARGE_OUT_GPIO_ENABLE() __GPIOC_CLK_ENABLE() uint8_t battery_i_charge_status = 0;
