Wait/Sleep

Other Parts Discussed in Thread: CC1310, SYSBIOS

Hi, I'm working with CCS and I want to know how can I make anything similar to sleep_ms or wait or whatever to stop de program 10seconds with a command.

Thank you!

Pol,

My apologies for the slow reply. We missed this one as it had a reply.

Is your project using TI-RTOS? There is a Task_sleep() function that can be used.

The compiler does have a __delay_cycles intrinsic that could be used.

__delay_cycles()

However this would use CPU cycles for the delay. If you want to really sleep during that time then I would ask in the sub 1-GHz forum what the best approach is.

Regards,

John

Thank you! I'll try with Task_sleep(), is it sleeping in miliseconds?

The input is "ticks" which can be configured. There is some information here: software-dl.ti.com/.../Clock.html

However I will ask someone to post a summary.

Not much to summarize but here goes:

All timeout arguments in SYS/BIOS APIs (ie Task_sleep(), Semaphore_pend(), Even_pend(), Mailbox_pend()) are in units of Clock module 'ticks'.

The default "tick" period for almost all devices is 1000us (ie 1ms).

To configure the tick period within the user's .cfg file:

var Clock = xdc.useModule('ti.sysbios.knl.Clock');

Clock.tickPeriod = 1000; /* units are in microseconds */
