Realtime Clock or just a "seconds counter"?

[eelcor 18]

Hi everybody,

 

I'm tinkering with my launchpad and was looking at the RTC functionality. As I posted in a different post, I am trying a symbiosis with the Raspberry Pi. It would be great to use the launchpad to switch on the Raspberry Pi and functioning as a very advanced intelligent peripheral.

 

However, the RTC confuses me. I am used to have several registers to store the date, time and alarms. The RTC of the launchpad just seems to be a timer counting seconds, nothing more. Is this correct? So if I want to make an alarm I should calculate the amount of seconds in the timer register?

 

Or am I missing something?

 

Kind regards, Eelco

It is just a counter. You will have to convert it into date-time. There is a function readily available for this in the /utils directory in Stellarisware

Okay, that's what I expected, not really a RTC, but very usable,

 

Thanks for the swift reply! Did you buy the J-link debugger, you mentioned in another thread or did you skip it?

 

Kind regards, Eelco

If you can some how set it to a set time you could just use it as
