Added access to logbook marker data:
In previous version event data could only be stored in memory but read back and usage in the OSTC itself was not supported. After the events like a marker set by the diver may be retrieved from the log.
Added visualization of markers to T3_Profile view

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;
