Raptor™ Data Logging

The blocks in this subsystem...

Overview

These blocks are installed with Raptor-Dev by default and included in the 'Raptor Data Logging' block library shown in the Simulink Library Browser. They are included in the standard Raptor-Dev license.

For DISP-IMX286 targets, these blocks provide access to create/read/write files on the USB stick.

For HCM-5604-036-1303, the 'Data Log Read', 'Data Log Write', 'Data Log Erase' blocks provide access to the 8MB of onboard datalogging flash.
