With ever increasing Connectivity options, Security Protocols and Sophisticated Human Interfaces, Software and AP developers find themselves caught more deeply in the dichotomy of dealing with increasing complexity of designs and shrinking timelines. Resource constraints and constantly evolving software landscape provide challenges to software Integration that have to be overcome to enable designers to focus on the actual application. Developers need a Modular Software Framework that accelerates software integration, provides flexible programming options and enables application re-use across multiple platforms. “That framework is MPLAB® Harmony.” Join us for the webinar series where we provide a technical overview of MPLAB® Harmony, Live tool demos, Microchip and third party Middleware support and finally demonstrate how Harmony accelerates software integration and moves development focus and resources to Application Development and testing. In this first installment of a three part webinar series attendees will learn: -Current Software Development Challenges and how MPLAB® Harmony, Microchip’s software framework, overcomes them. -Technical Overview of MPLAB® Harmony Framework. -Integrating RTOS in an embedded development ecosystem. -Graphics Application demo illustrating how MPLAB® Harmony facilitates changing system requirements.

Embedded Development
Challenges
• End Systems Sophistication Increasing
• Complexity of Projects Growing
• Development Time Stretching
• S/W % Total Development Time* à 60%
• Switching between RTOS leads to rework
• Lack of software compatibility creates new bugs
• Greater Risk with Re-­‐‑Work of Code
• Challenge to Integrate RTOS, Middleware,
Drivers All in One Platform
• Generally Multiple 3rd Party Software Suppliers
* 2014 UBM Embedded Market Study

8. Embedded Development Challenges
• Increased Verification & Debug Time Means
Less time to Focus on Critical Applications
• 60% of Software Resource Involved in Verification**
• Defects Found during Verification Costs 10x More Than Found in Design***
• Unpredictable Future Competitive Environments
• Increasing Pressure to Quickly Adapt
• Economic Risks of 3rd Party Companies
• Difficult to Procure all the S/W Components
from Single Vendor’s Website
• Full Feature Set Offerings are Costly
• Sca[ered Support for 3rd Party Offerings

17. Framework of Libraries
• Interface Functions
o Input, Process, Output
o May have “Side Effects”
o Treated as a “Black Box”
• Module
o One or more closely related functions
o Share common data or resources
o Maintain state of common resources
o Interface stays the same, even if implementation changes
• Provides Ability to “Divide & Conquer”

18. Multiple Clients & Instances
USART 1
USART 2
USART
Driver
Multiple Instances
Dynamic library modules can manage multiple
instances of same hardware.
• Avoids duplicating library code
• Simplifies application or client code
• Requires use of an instance “index”
Timer 1

Driver
TCP/IP
Console
File System
Multiple Clients
Multiple unrelated “clients” can access
common “server” modules.
• Localizes protection & maintenance of
shared resources
• Isolates clients from each other
• Requires use of a client “handle”
