Download Electron UPURS User Manual - Retro-kit

*UPLOAD <addr>
To load an image or file directly into an address within the Electron’s memory, you can issue the
*UPLOAD command with a hexadecimal address of the beginning of the memory space you wish to
upload the data to.
For example to *UPLOAD a data file into MODE 2 screen memory, you can issue the commands:
MODE 2
*UPLOAD 3000
NB: The example screenshots below use MODE 2 with a graphics and text window defined in order
to show the data loading process without overwriting the image data with output from *UPLOAD.
Fig. 14 - *UPLOAD 3000 command issued, waiting for data.
Fig. 15 - Data received and loaded between the values of &3000 and &6BFF.
NOTE: The address value passed to *UPLOAD must always be the address of a page boundary
within the Electron’s memory so must always be of the format &xx00. For example &0E00 and
&3000 are both okay but &0E20 and &3040 cannot be used.
