This command writes data to a card based on a VHL file.
In this file, you specify the card-specific memory structure. You can either add the VHL file to your reader configuration or create it dynamically using brp_VHL_Setup().
[in] | protocol | used to execute the command |
[in] | Id | ID of VHL file (starting at 0) * If you create the VHL file dynamically, use 0xFF. * If you've added the VHL file to the reader configuration, please resolve the ID from the filename using brp_VHL_ResolveFilename(). Don't hardcode the ID. Otherwise, your application won't work anymore if e.g. a project manager later merges VHL files into a different configuration using BALTECH ConfigEditor. This process may result in a new ID, but not in a new name. |
[in] | Adr | Address of the byte where you want to start writing |
[in] | Data | Data to write |
