IAR MakeApp for the Bluetooth IAR MakeApp for the Bluetooth protocol stackprotocol stack

A superior configuration and optimization tool!A superior configuration and optimization tool!

The importance of tool support• Most stacks come with no tool support for

configuration and optimization

• Manual adaptations are needed to use the stack on a new H/W or S/W platform

• Most stacks contain code for many features you don’t use –> waste of memory space!

• Manual optimizations are needed to get a fast and compact stack for your project

• You will need training courses or expensive consultants

• You will suffer a heavy development cost and time-to-market penalty!

The IAR MakeApp tool

• IAR MakeApp is the most powerful Bluetooth protocol stack optimization tool ever created!

• Advanced configurations are made within a few seconds on a high abstraction level

• The tool generates optimized and adapted Bluetooth protocol stacks in ANSI-C

• The stack becomes highly optimized for your H/W and S/W platform in seconds

• You save development time, production cost, and shorten time-to-market!

Feature highlights

• Highly graphical, ”CAD-like” drawing editor with drag & drop

• Optimizing code generator

• Built-in IAR Editor with source code syntax coloring

• HTML report generator creates detailed project reports with hypertext-links.

• Built-in HTML report viewer

• XML based file formats

Component model- Power and flexibility

• MakeApp supports many types of components, that can be added to the same project for configuration & code generation:

• Microcontrollers (8/16/32-bit, DSP)• External devices (Ethernet, LCD, USB, CAN, ASIC, FPGA)• S/W emulated peripherals (I2C)• S/W components (Bluetooth or TCP/IP stacks, Keyboard scan)

• Unprecedented flexibility – MakeApp becomes a code generation platform, that can generate source code for the complete embedded system!

Stack configuration

Environment

• H/W (Host CPU, Bluetooth device)

• S/W (RTOS, Compiler)

Stack features

• Core (HCI, L2CAP, RFCOMM, SDP, ...)

• Profiles (GAP, SDAP, SPP, ...)

• Other (TCI, Message logs, ...)

• Select API functions to implement

Configuration controls code generation

MakeApp helps the user focus on the application rather than MCU and stack internals!

ANSI-C code generation

Code adaptations

• The stack source code is generated for the selected H/W and S/W environment

• The generated stack source code only implements the selected stack features

Code optimizations

• Unused features and API functions are removed from the stack implementation

• Gives you a very compact stack = reduced memory usage and faster execution!

9

Code size affect production cost!

• The stack optimizer makes a ”vertical slice” of the stack and removes unused code

• The resulting stack becomes very compact and waste no ROM space

• Production cost is reduced as CPU and ROM requirements are lower!
