AWR1642BOOST: set framePeriodicity

user5153216

Part Number: AWR1642BOOST

hello，How much the Maximum of the framePeriodicity can be set in frameCfg ?the variable framePeriodicity is rlUInt32_t type.iie,2^32*5/1000000=21474.83648ms=21.474.83648s.when I set it as the values ( 21000,15000,10000,5000,1000)，it all appear errors!when I set it as 800, it is correct！

Where are you pulling your calculation from? Where does this formula come from: 2^32*5/1000000=21474.83648ms.

A typical range for range periodicity is from 1 ms to 1000 ms.

Please reply if you have any additional questions.

Regards,
Kyle

rlUInt32_t framePeriodicity;The variable framePeriodicity is defined as rlUInt32_t,therefore I think so.

Yes, I can see the variable you are referring to.

Variable: rlUInt32_t framePeriodicity
Location: rl_sensor.h

In the comments for this variable, it states that this variable is the frame repetition period with an LSB of 5 ns and typical range of 1 ms to 1000 ms.

It is not clear from any of your previous posts where you are pulling the equation you are referencing from, as it is not mentioned in any of the header files.

Perhaps there may be some confusion about how this parameter is passed in through the CLI using the mmwavelink API. For the frameCfg command, no calcuations are needed. You just need to pass in the value you want in milliseconds. So if you want to pass in a 50 millisecond frame repetition, a value of 50 would be passed in as the fifth argument.

Let us know if you have any additional questions regarding this issue.

Regards,
Kyle
