Images and Fonts

The HMI file system allows you to store images and fonts that can then be displayed in your application.  SPLat/PC does not manage these files, instead you must manually place them in the Internal Storage directory of the HMI.

Firmware

HMI firmware is updated from time to time and you can update your HMI via the file system:

  1. Unzip the hmi430.srec or hmi700.srec firmware file.
  2. Drag the hmi430.srec or hmi700.srec file to the System Firmware folder.
  3. That’s it – the update takes about 1 minute.

Application Distribution

You can also precompile your SPLat application and send this file to your end customer.  This means they won’t see your secret source code and they won’t have to mess around with SPLat/PC.  Refer to this page to see how to create a .b1n file.  Once it’s made, simply drag and drop it into the System Firmware folder.  Be sure to send any changed or new images and fonts as these will need to be manually placed in the Internal Storage folder.

ScreenShots

All touch-screen controllers have an automatic facility for taking screenshots.  With the controller plugged into the USB port, navigate to the “Internal Storage” folder of the device:

Within that folder is a file initially called “sshot000.png”.  Drag that file to your desktop or a target location and the HMI firmware will automatically make a screenshot in this file.  (The HMI700 generally takes some time to do this.)  It will also increment the file name, so the next file will be called “sshot001.png”.

Easy peasy screenshots.
