The RTC is configured to generate an interrupt every second and also when the alarmtime is reached. Note: This is the latest in a series of beginner level tutorials for Arduino, the open source electronics The Arduino uses Timer 0 internally for the millis() and delay() functions, so be warned that changing the frequency of this timer will cause those functions to be erroneous. ” Often users go throwing it into programs without fully understanding what it does. It doesn’t help that it’s functionality changed when version 1. So I would set up a seconds interrupt from the RTC and snapshot the current Systick. We use cookies for various purposes including analytics. Up to now we have carefully avoided any serious handling of one of the most important system concepts: the passage of time. This fix works because each time the interrupt handler is executed, it compares the current time retrieved by the function millis() with the time the handler was last called. 2V. It was made using CCS V6 with TI compiler. c Used on an STM32F103 in a wireless remote control (C) 2010 Christoph Gommel <[email protected] Maple was one of the first ARM Cortex-M3 microcontroller boards, all designed and built by LeafLabs.
