DanNduati / igh_rtc

RTC driver for Farmshield IoT Devices

Igh system RTC HAL driver

Module name: igh_time

The module has the following public APIs:

void igh_time_init(void); //initializes the rtc module
bool igh_time_is_valid( void ); // returns true if current time is after January 1st 2021
uint32_t igh_time_now( void ); // returns the current unix time
bool igh_time_set( uint32_t unix_time ); // sets the current RTC time and returns true if 
successful
DateTime igh_datetime(void);//returns a DateTime object of the current time

Flashing to device over serial

$ make flash

This will build the firmware and put the device in dfu mode ready to be flashed with the firmware binary via usb.

Expected output

daniel@dan:~/Desktop/synnefa/firmware/rtc_test$ make flash
