4.5 Module's direct open
If there is a need to launch the module directly from the file browser contextual menu, an
additional method should be added in the module structure for the direct open feature. This
callback is often named _ModuleName_DirectOpen.
Figure 31 is an example of how to open a file using the adequate module from the file
browser.
Figure 31. Direct open from file browser
In the STM32CubeF4 demonstration, there are three modules linked to the file browser
contextual menu:
• The video player
(1)
, supporting the format:
– emf
• The image browser , supporting the formats:
– jpg
– bmp
•
The audio player , supporting the format:
– wav.
Then, to link the module to the file browser open menu, the command k_ModuleOpenLink()
is called after the module is added.
1. The video player is not supported by STM32446E-EVAL demonstration.
