Advanced Software Framework Version 4(ASF4)Introduction and Context This chapter starts with an overview of the features and objectives of asf4. the context in the larger SW/ Tools ecosystem is defined, giving a relation between the ASF4, START, and the IDE. A high-level work- flow overview is presented and documentation resources are described to give insight into which references to use for what 1.1 Introduction to asF4 ASF4 is a collection of software components such as peripheral drivers middleware and software applications provided by Microchip. The framework supports the Microchip's SAM family of microcontrollers Unlike older versions of the software framework, version 4 is designed to work together with Atmel START Atmel START is a web-based user interface, which allows the users to configure code according to their needs. The configuration is input to START's code generator, resulting in an optimal code implementing exactly the functionality configured by the user. The generated C-code is exported from START and into the user's development environment of choice for modification and compilation The tight integration with Atmel START means that the asF4 code is more tailored to the users specification than before. For instance, instead of using c preprocessor conditional expressions to enable/disable code blocks, disabled code blocks can be entirely removed from the project source, which results in cleaner and easier to read code. the integration into Atmel start means that software configuration is done in a much more user-friendly environment and the only configuration information loaded on the device is the raw peripheral register content, which makes the firmware image much more compact Code generation results in smaller and faster code compared to previous versions of ASF ASF4 has many improvements compared to previous ASF versions Common set of software interfaces across different devices Smaller code size · Easier to use Common set of software interfaces across different devices ASF4 has a set of fully hardware-abstracted interfaces as a part of the core architecture. These interfaces are use-case driven and supports only a subset of the functionality offered by the hardware. One hardware module is typically supported by multiple interfaces, and START is used to select which nterfaces to be included in his project. Providing common interfaces that are completely abstracted from the hardware makes them easier to use in middleware and software stacks since it is not necessary to add architecture specific code Smaller code size Having StaRT generate the code exactly matching the required configuration reduces the code size according to drivers in previous versions of ASF. Full featured and generic drivers make it hard for the driver developer to make optimal decisions for often mutually exclusive design parameters, such as like high speed, low power, low code size, ease of use, and advanced feature support. Such drivers often miss the target in many applications because some of the parameters are wrongly tuned for the application in mind. However, limiting the scope of the driver to a specific use-case, ASF4 drivers are able to get the balance between these parameters right C 2018 Microchip Technology Inc User Guide D$50002633B-page 8 ASF4 API Reference Manual Advanced Software Framework Version 4(ASF4) Use-case drivers limit the driver functionality to the functionality required by the user, which usually is a subset of the full functionality provided by the peripheral. The use-cases can also tailor the driver to work in a specific environment such as Barebone synchronous, optimized to be used on the"bare metal"(os less application) RTOS asynchronous optimized to be used with an rtos See 1.5 ASFv4 vs ASFv3 Benchmark for more details on improved code efficiency Easier to use ASF4 is easy to use due to Graphical configuration of the system through Atmel START Use-case drivers offering only the functionality required by the user's application, reducing the configuration complexity compared to full-featured generic drivers. asf4 provides multiple use case drivers for each peripheral, each with a specific application target 1.2 ASF4: Atmel START Software Content and Ides This section gives an overview of ASF4 within the larger context of the SAM Tools ecosystem Getting Started Topics AVR sAM Tools: Intro Overview MICROCHIP In this video: Context in Microchip Tools Ecosystem 1E-Bit PICMO and dEPCE 32部 t PIC MCU 注Mc SAM MEI IDE, Compiler, MCU sw configurator tools Firmware libraries MPLAB Kores Di tOod Based START Software Content and iDEs How these pieces fit together uIPLAg XC C Compile ANGCCC ARM GCCC Camp lers Compilers START-based development STARTuser manual Getting Started projects in START Atmel studio 7 Microchip Lbrariesfor MOLAE 山 dancee setana Framework Bare-metal- VS START-based development Build from scratch(bare-metal) MPLAB XC PRO C Compiler Literes Getting Started Atmel Studio 7 Workbench Workbench 型MD Getting Started with AVR Tools Video: AVR and saM Tools ecosystem overview 1.2.1 Atme start Atmel START is a web-based software configuration tool for various software frameworks, which helps you get started with MCU development. Starting from either a new project or an example project, Atmel START allows you to select and configure software components( from asF4 and AVR Code), such as drivers and middleware to tailor your embedded application in a usable and optimized manner.
