hi geeks,thank you in advance i have doubt in lm3s6965 evaluation kit. can i change the freqency and voltage of the processor and peripheral dynamically in run time.
Do you care to - perhaps - "lift the curtain" a bit so that, "change the voltage of the processor" is made somewhat clear?
Suspect that, "System Frequency" change is possible - provided that you obey the crucial linkage to MCU on-board xtal matching its mated parameter w/in "SysCtlClockSet()." We have - 3-4 years past - employed this in the attempt to reduce power draw and/or achieve slight "performance tweaks" during mission-critical code segments. (Very briefly) This may be Stellaris device sensitive - suggest that you not try this on an, "unrecoverable Stellaris MCU." (i.e. Sandstorm)
cb1_mobile thank you for reply. i am beginner of TI microcontroller. so please can you give me detail information about my question and your reply
dinesh arunachalam i am beginner of TI microcontroller
Both questions you ask seem very unusual for a "beginner" - unless you're migrating from another MCU - and have encountered just such issues. Should that be the case - one suspects that you've developed test/verify protocols - and should be able to adapt these for use w/Stellaris.
Remains unclear to myself/others as to "why" you've chosen those specific questions...

cb1_mobile thank you. i am migrating from NXP to TI MCU. i am going to do my Post graduate project in power efficient embedded web server. for saving the power consumption i should use DVFS algorithm. Could it be posibble?? help me!!
Aha - curtain at last opened - now some, "reachable target" revealed! Might it make sense to include such detail - from your very first post? Vagueness and nature of 1st post drew me in - but I am, "out of my league" re: your issue. At least - with new detail provided - others should be better able to assist. Good luck...
cb1_mobile :) :)!!!... i have this idea to do and i also do not have comlpete figure. now only i started with lm3s6965 ADC peripheral.
Forgive me - your task appears large - very ambitious - and much outside my limited expertise/competence. (if any) Myself/others here may be able to guide you w/basics of Stellaris set-up/operation - but detailed help you likely require - beyond my pay-grade.
Do suggest that you allow plenty of time to explore w/your Stellaris - rush most always leads to unpleasant results - will set you back in the long run. ADC peripheral you mention is one of the more complex ones - I'd suggest that you start w/simple GPIO and then progress to simple Timer, then perhaps UART. After mastering those - believe you'll be stronger/more confident with your MCU and IDE - thus better able to do battle w/ Stellaris ADC. ADC is powerful - but trades performance for quick understanding/mastery - really not an ideal "first learning" choice.
Wish you well - you may wish to follow my guide and then prepare fresh post - with much more focused/clear topic - to receive further assistance. Bon chance mon ami...
cb1_mobile :) :) thank you :)... i do hope for improvement
