DLOG_4CH_buff1 cannot load from non-primitive location

Hi,

This message means, that you are trying to display a non primitive variable. What data type did you attach to the DLOG module? is it a struct maybe?

Hi Andeas,

I indeed try to output a structure member to data log. The data type of the structure member is _iq. Before entering data log, it is converted to suit data log data type by (unit16)_IQtoIQ15. I think it is proper data log type. Can't see why it is not a primitive data type.

Thanks.

How did you assign the data to the log module? did you just cast the struct member? I would recommend to cast the data into a suitable variable first and then attach this variable to the log module.

Hi Andreas,

You are right. I just cast the structure member to data log. Probably I should cast the value to a variable and then data log it.

My solution is to create a buffer array myself and store relevant values into array during every interrupt, and it works fine.

Thank you.
