Description
t c u
d o r
P e
The STEVAL-CCM001V1 demonstration board is a standalone digital photo frame application designed using the STM32F103RB Cortex M3 microcontroller.
t e l o
s b O
The digital photo frame is used to display digital images in slideshow style. Unlike the static display of traditional photo frames, the images in the digital photo frame change automatically at regular intervals which are set by the user. The application is capable of managing JPEG decompression with the 20 KB of RAM in the STM32F103RB microprocessor. The FAT16 / FAT32 system library is used for reading JPEG images from the Micro SD card. The STEVAL-CCM001V1 can be powered by an external battery, as well as by a USB connector.
