Hi!, We are using Halscope to get data saved into a file while running our hexaglide, and using that file to do various things as for example identification or parameter estimation.
To that end we need to know about the precise time instant in which the data is collected. For example let say that we are recording: pid output, feedback, and cmd at the same frequency of the thread that runs the hal component updating functions. In our case all the functions of the components are running in the same thread, but we don't know when is halscope reading the data: before, during or after all the functions of the hal components in the given thread has been updated. That information can be relevant in the context of identification / parameter estimation, analysis of a control algorithm implementation using halscope. As for identification the needed data is encoder count and analog outputs at the same time instant I would like to be able to get the data just after the both updating functions has been called so data will be as fresh as possible. I would like to understand better how halscope works synchronizes with the updating functions. Can we control exactly between which updating functions is halscope going to read the data? Thank you very much, Javier Ros ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
