Detailed Description

EXternal peripherals.

Under ChibiOS the set of the complex device driver interfaces dedicated to external peripherals is called the EX subsystem. The EX resides on top of HAL and is actually a set of libraries for external devices like MEMS, Displays, Flash memories and so on. These libraries are the implementation of one or more Abstract Interfaces brought by HAL subsystem. EX also relies on HAL normal drivers to interface the peripherals.

EX Complex Drivers Architecture

Each EX driver can be considered as a standalone Complex Device Driver. For ease of use these drivers are grouped by vendor:

• Bosch Devices
• Micron Technology Devices
• STMicroelectronics Devices
