CC1352R: Execute task every few hours

user5943842

Part Number: CC1352R

Hi,

I would like to execute a task once every few hours. However, if I am not mistaken, the uint width of the parameters for Task_sleep and the Clock library do not allow for such long periods of time.

((2^31 * Clock_tickPeriod) / 1000000 / 3600 = 5.9 hours), meaning that that is the limit?

What is the usual way to tackle this?

Hi,

I sent it to a concerned engineer. We will get back to you ASAP. Please bear with us.

Thanks,

Hello,

The argument for Task_sleep() is a number of system Clock ticks. By default the Clock tick period for CC26xx and CC13xx devices is configured at 10 microseconds. So this means, with a 32-bit tick counter, the default maximum duration for Task_sleep() is 11.93 hours.

I would suggest you to use a scheduled timer event which might be easier.
