Multimedia peripherals are discrete components that are connected to the microcontroller by a bus. Support for LCD touchscreens, audio codecs, and camera peripherals is a very attractive feature of the STM32F4xxx microcontroller, and selecting an evaluation board that includes these peripherals, although more expensive, will increase the range of projects that can be undertaken. Multimedia projects using the touchscreen and codec are great fun and much more likely to motivate young programmers than blinking LEDs. These peripherals are quite complex, but the libraries that are provided to support them are reasonably straightforward to use.
