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.

Blocks

Block	Description	Appearance
Erase	This block is used to erase a value from the data log.	Erase block
Read	This block is used to read a value from the data log.	Read block
Write	This block is used to write a value to the data log.	Write block
USB Eject	When this block executes, all pending data to the USB drive is stored and the drive can be safely unmounted.	USB Eject block
USB Status	This block shows the current status of the USB drive.	USB Status block
File Close	This block closes and opens a file and flushes all data written to the file system. All files should be closed before the module powers off to ensure data is not lost.	File Close block
File EOF	This block is used to determine if the current file position is at the end of the file.	File EOF block
File Exists	This block can be used to detect if a file exists on the specified resource.	File Exists block
File Get Free Space	This block returns the free space on the specified resource.	File Get Free Space block
Open File	This block opens a file for read and/or write. It outputs a file handle which is used with other blocks to read, write, and seek within the file.	Open File block
File Position	This block is used to get the current file position measured in bytes from the start of the file.	File Position block
Read File	This block is used to read the contents of a file.	Read File block
Remove File	This block removes a file from the specified resource.	Remove File block
Rename File	This block is used to rename a file on a resource. It cannot be used to move a file between resources.	Rename File block
Seek File	This block is used to move the current position in a file where the next read or write operation will occur.	Seek File block
File Size	This block returns the size of the specified file in bytes.	File Size block
File Sync	This block flushes all pending data writes to the flash file system.	File Sync block
Write File	This block is used to write data to a file. The block accepts uint8 or string data types.	Write File block
