To be truly useful, an embedded device must be able to interface with hardware components. This chapter describes how you can access general purpose input/output (GPIO) ports, transfer data with the RS232 serial port, and interface with devices on the inter-integrated circuit (I2C) and serial peripheral interface (SPI) busses. Further, you will learn how to access files on mass storage media with a file system such as SD cards and obtain information about the charging state, processor speed, and system identification. This chapter also tells you where to find USB device samples to let your .NET Micro Framework act as a USB device like a mouse.
