Multiple(five) alarm time setting in stm32f0 mcu












3















I am working on my hobbyist project and need to develop the alarm timings.
And RTC and Timer are new for me and I am confused in RTC Alarm time setting.
I need to make alarm with RTC for five different times(as we are doing in the mobile).
So, I am looking for the same thing with my mcu.
Looking forward for the kind support ...
(I am using STM32 Nucleo Board, KEIL-IDE, CubeMX)



Thanks

            There are only two Alarms but you can always make a software alarm and implement that (different discussion on the details of that)



            I got this on the keil website and it helped me to understand the RTC functionality a bit better: http://www.keil.com/download/docs/356.asp



            I know it is not for the STM32F0 but I had to modify only a little bit of code in order to get it going

                              Is this a new Fibonacci Identity?

                              6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
