Hallo,
I need to put the MC13224 in low power mode. The problem is that this node is a coordinator that works as a remote and portable controller. The beekit permits the low power mode only for an end device. In my case I have a network where the coordinator asks and the others answer so I can decide when weak-up. Can some one give me info about how to configure or change the beekit generation tu put a coordinator in low power?
Thank you.
Regards
hello,
i'm testing low power mode on mc13224v, in hibernate mode i use 2KHz internal oscillator. This can change from 1KHz to 4KHz, but i see a frequence of 20KHz! It's too differente!
Only changing Ftune and Ctune of RING_OSCILLATOR_REGISTER i have 2KHz.
Can someone help me?
bye

Giada,
When I use the "2kHz" internal oscillator I first run the calibration sequence using CAL_CNTL to determine exactly was speed it is running at. I then use this calibrated clock to determine how many cycles to sleep for.
You can find an example of this here:
