How to set Tick to 1ms in FreeRTOS

6 months ago

Hi xuguodong,

Why do you need to change the OS tick?

The chip is running with the 16MHz in active mode and with the 32.768MHz ins sleep mode, which is the Low Power Clock.

Thanks, PM_Dialog

Hi Dialog,

I know that 6MHz and 32.768MHz are external active oscillators.

My issue is as follow:

What is the actual working clock frequency of DA14683 in software code?

Hi Dialog,

Our external oscillators are 32.768MHz and 16MHz. How to enable the maximum frequency(96MHz) of DA14683?

Hi xuguodong,

The cm_sys_clk_init() should be used in order to initialize clocks after power-up. It takes as an input parameter the clock source to be used as the system clock.

Hi Dialog,

Only the declaration of this function was found, no implementation.

Hi xuguodong,

It can be found in sys_clock_mgr.c of the SDK. I’d recommend just using the cm_sys_clk_init() and prevent modifying the source code.

Hi Dialog，

How to use cm_sys_clk_init? can you give me example code?

I only set working frequency of cpu to 96MHz.

Thanks.

Hi xuguodong,

Please take a look at any of the SDK1 examples : in the system_init() there is the clock initialization.

Thanks, PM_Dialog
