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. |
|
Read |
This block is used to read a value from the data log. |
|
Write |
This block is used to write a value to the data log. |
|
USB Eject | When this block executes, all pending data to the USB drive is stored and the drive can be safely unmounted. |
|
USB Status | This block shows the current status of the USB drive. |
|
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 EOF | This block is used to determine if the current file position is at the end of the file. |
|
File Exists | This block can be used to detect if a file exists on the specified resource. |
|
File Get Free Space | This block returns the free space on the specified resource. |
|
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. |
|
File Position | This block is used to get the current file position measured in bytes from the start of the file. |
|
Read File | This block is used to read the contents of a file. |
|
Remove File | This block removes a file from the specified resource. |
|
Rename File | This block is used to rename a file on a resource. It cannot be used to move a file between resources. |
|
Seek File | This block is used to move the current position in a file where the next read or write operation will occur. |
|
File Size | This block returns the size of the specified file in bytes. |
|
File Sync | This block flushes all pending data writes to the flash file system. |
|
Write File | This block is used to write data to a file. The block accepts uint8 or string data types. |
