Microchip Certified Training - PIC18 Foundation Workshop using Assembly Code — A 3 day course
This hands-on course aims to provide engineers with an understanding of the enhanced PIC18 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.
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 ICD programmer/debugger and a target development board containing a PIC16C / PIC16F microcontroller on which programs created during the exercises can be observed to be running in real-time.
The course will help delegates understand the architecture and features of the PIC18C / PIC18F family of microcontrollers and gain hands-on experience of Microchip development tools for creating and debugging assembly language programs on a target PIC18C / PIC18F microcontroller. Delegates will also be introduced to the use of on-chip peripherals to simplify interfaces to the outside world.
This course will provide delegates with the following skills:
- Programme object code into a target PIC18F microcontroller using MPLAB and MPLAB ICD2
- Create, build and debug new assembly language projects using MPLAB and MPLAB ICD2
- Understand the components of an assembly source file
- Set the PIC18 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
- Implement fixed tables of data in program memory

This course is aimed at engineers with some understanding of microelectronics and programming who are new to the PIC18C / PIC18F architecture, or wish to fill in gaps in their knowledge.
Familiarity with the 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.
