CMSIS-Driver

The standard peripheral driver interfaces connect microcontroller peripherals for example with middleware that implements communication stacks, file systems, or graphic user interfaces. Each peripheral driver interface may provide multiple instances reflecting the multiple physical interfaces of the same type in a device. For example, two physical SPI interfaces are reflected with separate Access Structs for SPI0 and SPI1. An Access Struct is the interface of a driver to the middleware component or the user application.

Reference Implementation

To simplify the development of a CMSIS-Driver both Driver Template Files and Driver Examples are provided. Template applications using CMSIS-Driver and Middleware are available from the CMSIS Workshop.

CMSIS-Driver Validation Suite

ARM offers a CMSIS-Driver Validation Pack which contains the source code and documentation of the CMSIS-Driver Validation Suite. Examples show the usage of the test suite on various target platforms.

The CMSIS-Driver Validation Suite tests for API function calls and configuration parameters. It can do communication tests with loopback and check for communication parameters such as baudrate etc. For details, refer to the CMSIS-Driver Validation Pack Documentation.

List of Supported Devices

CMSIS-Driver are delivered as part of a Device Family Pack. The following Packs contain such drivers:
