MSP430G2553 Timer Intervals [closed]

Answer 1

it is quite simple,\

You have a 1 second timer, that causes an interrupt every 1 second.

Your other times are multiples of that 1 second.

So, at the start of your program set a 10second counter to 0 and set a 1minute counter to 0.

At each 1 second interrupt, increment both counters.

Each time the 10 second counter steps from 9 to 10

1. reset that counter to 0
2. process the 10 second activity

Each time the 1 minute counter steps from 59 to 60

1. reset that counter to 0
2. process the 1 minute activity
