PIC16F Foundation Workshop using Assembly Code
PIC16F Foundation Workshop using Assembly Code
| Duration: 3 Days |  Microchip Certified Training |
Intended Audience
This course is aimed at engineers with some understanding of microelectronics and programming who are new to the PIC16F architecture, or wish to fill in gaps in their knowledge.
Familiarity with the Microsoft Windows environment on a Personal Computer, and with fundamental concepts such as bits, bytes, Boolean logic and addressing is assumed.
Some experience of assembly language on microprocessors or other microcontrollers will be useful background for an understanding of the more advanced concepts presented during this course.
Course Overview
This "hands-on" course aims to provide engineers with an understanding of the PIC16F family of microcontrollers and experience of using Microchip development tools to create and debug simple assembly language programs. The emphasis is on providing a solid foundation of knowledge of the architecture and features of this range of microcontrollers, together with practical experience of the development tools and the steps required to embark on a new development.
Key Skills
- Understand the architecture and features of the PIC16F family of microcontrollers
- Gain hands-on experience of Microchip development tools for creating and debugging assembly language programs on a target PIC16F microcontroller
- Be introduced to the use of on-chip peripherals to simplify interfaces to the outside world
Practical Work
The course includes many practical workshop exercises which are interleaved with the relevant presentation material for maximum impact and variety. These exercises are carried out using MPLAB software running on a Windows PC, an ICD3 programmer/debugger and a target development board containing a PIC16F microcontroller on which programs created during the exercises can be observed to be running in real-time.
Laboratory Workshops Include:
- Programme object code into a target PIC16F microcontroller using MPLAB and ICD3
- Create, build and debug new assembly language projects using MPLAB and ICD3
- Use MPSIM to simulate and debug code prior to programming it into a target device
- Understand the components of an assembly source file
- Set the PIC16F configuration options appropriately for the target system
- Use digital I/O ports to interact with the outside world
- Manipulate data memory using direct and indirect addressing
- Create time delays using software loops and hardware timers
- Take advantage of interrupts to handle events in the background
- Jump and call routines across pages in program memory
- Use PC-relative addressing to implement look-up tables
- Implement robust design techniques to protect against malfunctions
