Bugfix: make date/time setting work over reboots
Setting the time/date over the UART interface or by the menu, seems
to work, but a reboot of the RTE brings back strange, seemingly
random, time.
The reason for this is rather simple. In the settings, a time
is stored, based on some flawed logic, and that time was restored
on reboot. There is no reason to store any time, when the moment of
restoring it is unrelated in time. So, the fix is simple: do not
set time (in the RTC) based on some time from the past. The whole idea
of a RTC is that it does preserve the time for you, as long its
powered. Any attempt to do things better using stored time data is
futile (and nonsense).
And while working on his, also kick out some useless code from the RTE.
There is no reason to initialize the time on the RTC to some random
time/date in the past. A zero data/time is as good and any random
date.

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;
