SysBios - ClkCountSpms Is Missing

Other Parts Discussed in Thread: SYSBIOS

Hi,

In DSP/BIOS, I used the CLK_countspms function to get number of hardware timer register ticks per millisecond.

Now that I moved to Sys/Bios, this function is no longer supported.

How can I retrieve this value in Sys/Bios?

Thanks,

Hi Gilad,

What version of SYS/BIOS are you using? What device are you developing on?

Thanks,

Hi Emmanuel,

Sys/Bios version is 6.33.05.46, I'm developing on DM8148's C674x dsp.

Same question for Dsp/Bios "CLK_gethtime" function, what function replace it in Sys/Bios?

Thank you,

Gilad

Hi Gilad,

The Clock module within SYS/BIOS has a family-dependent constant called Clock_tickPeriod which has period in microseconds. TI platforms have a default of 1000 microseconds. The Clock_getTicks() function provides the time (the system has been running) in clock ticks.

The Clock API can be found in:

<BIOS install dir>\docs\Bios_APIs.html -> ti.sysbios.knl.Clock

Thanks,
