I'm using STM32F103 with CubeMX.
I enabled the RTC Global Interrupt but I don't know how to configure it to generate a 1/4 second interrupt?
Because the Reference Manual says:
Three dedicated maskable interrupt lines:
– Alarm interrupt, for generating a software programmable alarm interrupt.
– Seconds interrupt, for generating a periodic interrupt signal with a programmable
period length (up to 1 second).
– Overflow interrupt, to detect when the internal programmable counter rolls over to
Could anybody show me how to configure this with HAL Library?
