The STM32 behave as a mass storage Host that can enumerate, show content and display the supported BMP image in the attached USB flash disk. When the user press the user key button [B4], the application explore the USB flash disk content and display it on the LCD. The user has to press the user key button to display the whole disk flash (recursion level 2). Once the entire disk flash content is explored, the user has to press the user key button to write a small file (less to 1 KB) on the disk. After writing the file to the disk, the user can press the user key button and start the Image slide show (BMP file located in the USB Disk root). Once all the images are displayed, the application explores again the disk flash. @note Only the BMP files with the following format are supported : - width : 320 - Height : 240 - BPP : 16 - Compression : RGB bitmap with RGB masks To use the Image browser, copy the BMP files from "\Utilities\Binary\Media" to the root of the USB flash disk to be used. This example works - in high speed (HS) when the STM322xG-EVAL or the STM324xG-EVAL board and the USB OTG HS peripheral are used - in full speed (FS) when the STM322xG-EVAL or the STM324xG-EVAL board and the USB OTG FS peripheral are used, or when using the STM3210C-EVAL board. @par Hardware and Software environment - This example runs on STM32F105/7 Connectivity line, STM32F2xx and STM32F4xx devices. - This example has been tested with STM3210C-EVAL RevB (STM32F105/7 devices), STM322xG-EVAL RevB (STM32F2xx) and STM324xG-EVAL RevB (STM32F4xx) - STM3210C-EVAL Set-up - Use CN2 connector to connect the board to a PC host or USB device - STM322xG-EVAL Set-up - Use CN8 connector to connect the board to a PC host when using USB OTG FS peripheral. - Use CN9 connector to connect the board to a PC host when using USB OTG HS peripheral. - STM324xG-EVAL Set-up - Use CN8 connector to connect the board to a PC host when using USB OTG FS peripheral. - Use CN9 connector to connect the board to a PC host when using USB OTG HS peripheral. @par How to use it ?
