Brief introduction
The MR framework is a lightweight framework designed specifically for embedded systems. It fully considers the
resource and performance requirements of embedded systems.
By providing standardized device management interfaces, it greatly simplifies the development of embedded applications and helps developers quickly build embedded applications.
The framework provides developers with standardized open, close, ioctl, read, write and other
interfaces. It decouples the applications from the low-level hardware drivers. The applications do not need to know the
implementation details of the drivers.
When the hardware changes, the applications can seamlessly migrate to the new hardware by only adapting the low-level drivers. This greatly improves the reusability of software and its extensibility to new hardware.
Key characteristic
- Standardized device access interfaces
- Decoupled application and driver development
- Simplified lower-level driver and application development
- Lightweight and easy to use with low resource usage
- Modular design with loose coupling between components for independent development and extremely low hardware migration costs
- Supported in bare-metal and operating system environments
Major component
- Device framework: Provides standardized device access interfaces
- Memory management: Dynamic memory management
- Tools: Common data structures like lists, queues, balanced trees etc.
- Various functional components
Standardized device interface
All operations of the device can be implemented through the following interfaces:
| interface | describe |
|---|---|
| mr_dev_register | Registered device |
| mr_dev_open | Open device |
| mr_dev_close | Close device |
| mr_dev_ioctl | Control device |
| mr_dev_read | Read data from the device |
| mr_dev_write | Writes data to the device |
| mr_dev_isr | Device interrupt control |
Configuration tool
MR provides Kconfig visual configuration tool that developers can configure without deep knowledge of the source
code.
Kconfig will automatically generate the configuration options interface based on the configuration file. Developers
can select the functional components that need to be enabled and set relevant parameters through simple operations.
By modifying parameters, you can quickly tailor the required functions. After the configuration is complete,
the Python script automatically generates the configuration file.
