ext_Flash_write_sample erase sector optimization:
The previous function erased a sector while writing sample data causing a delay of up to 200ms. The new implementation checks at the end of a write sample call if we are close to a sector end. In case we are a erase sector command will be send to the flash for the next sector. At the time of the next sample write (2 seconds later) the next sector is already erased and no busy wait of 200ms is needed => max write time for samples is not less than 5ms.

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;
