I have succeeded in connecting two Tic T249’s via two USB ports on my computer. I am able to change the AGC setting in Tic Control Center, and click apply settings, which changes from blue to gray, and the “unsaved changes” warning goes away.
However, when I change my selected Tic in the “Connected to” drop-down, and switch back, my AGC settings are erased and revert to “OFF”. All of the other settings I’ve tried (step mode, max speed/accel, etc.) do not have this behavior.
In reading the user guide section 6, https://www.pololu.com/docs/0J71/6, I don’t see this specific behavior for AGC mode clearly documented, but I may be misreading it. I also checked the TB67S249FTG datasheet and application note mentioned on the settings page, and could not find this behavior mentioned (again, I may be misreading the notes as I did not understand 100% of the verbiage).
Is this a Tic Control Center error, user error, potential board problem, etc.?
