Hello
What oscillator is a default source for system clocks in TI-RTOS for CC2640 ? The only information I have found in configuration file is 48MHz CPU frequency. I need to make HF XTAL (24 MHz) as clock source for my application. How can I do it by means of TI-RTOS ?
Regards
Mikhail,
Which version of TI-RTOS are you using, and which tools (CCS or IAR)?
The default high frequency (HF) clock source is selected via customer configuration setting in a file named ccfg.c. I expect you have a file ccfg.c in your application project. It may have actual content, or it might do a “#include <startup_files/ccfg.c>” to pull in the default configuration structure as defined by the driver library (driverlib). If the later, there are comments in this file about how to copy the default file into your project, and change the settings locally.
In the default ccfg.c there is a #define to define whether the HF source is a 48MHz or 24MHz crystal, for example:
I think the CPU will always run at 48MHz, and this setting just defines the frequency of the HF crystal you are using. Does this answer your question?
Thanks,
Scott
