STEVAL-CCM001V2图像演示板

Graphic panel demonstration board based on the STM32

The STM32-based STEVAL-CCM001V2 graphic panel demonstration board displays images oneby- one in a slideshow fashion. The heart of this board is the STM32 microcontroller, which is capable of reading a memory card containing photographs, and display them on a TFT screen. The memory used to store the images is a microSD card. A 3-axis MEMS accelerometer is used for picture orientation.With the growing popularity of digital cameras and cellular phones with high-pixel photo capability, it is becoming more common for people to store digital photos in storage media rather than producing prints. Digital photo frames are an ideal solution to preview digital images. Bundling image display solutions with the STM32 shows the capability of this microcontroller in the world of multimedia. Additional features of the board include display of room temperature, date and time, a touchscreen-based keypad as user interface, USB mass storage, ZigBee? and a rechargeable battery system.

The application can be used either as a standalone solution, or combined with other

applications such as POS, card readers, security panels, USB speakers or high-end remote controls.
