Read text from a file
NOTE: Curently trying to store more than 254 bytes in a device variable can lead to a segmentation fault. Therefore, if a file is bigger than 254 bytes, only the first 254 bytes of the file contents will be currently be stored. A modification is needed in devices.c to fix this.
Options
| Name | Required | Multiple Values | Description |
|---|---|---|---|
| FROM | yes | no | The full file path |
| DEVICE | yes | no | A label device to store the text read |
Examples
IF 1 == 1 THEN read FROM /home/pi/myfile.txt DEVICE mylabel => reads content from the file and stores it in mylabel
Note: if the file cannot be opened the cause of the failure will be stored in the color attribute of the label.
