Ok, I am working on a new, and eventually freeware utility that will allow better control and more visible stepping of the PXA27x cpu to it's other frequencies. Standard Frequencies that is.
I am not sure if this is the right forum for this, but if there are any developers out there my question is:
I need to be able to set the clock frequency for the Intel XScale PXA27X dynamically from within Win CE. I looked to see if the Win CE Power Manager libraries (and other libraries in coredll lib) contain any functions to set the clock or least the IPM parameters but they do not. Just contain sleep modes, battery status, etc.
So, before I develop a driver which will communicate to the Intel SpeedStep Power Manager (via I2c) I would like to know if there is either another built in driver lib. or a 3rd party driver that would allow the integration to this app.
I wonder what XCPUScaler and Power Hack Master is using. And whatever method the HTC Performance Utility uses, I would love to get my hands on because there is no running applications or processes. I am thinking it is storing the new freq's directly to the IPM EEPROM or could use another HTC OEM driver...
If someone can help me with this one thing; I promise I will get you this util made fast.

Thanks a mil!
