Introduction to Microcontrollers Lab Manual DEVELOPMENT HARDWARE These labs are based on the MX Module series manufactured by Stratford Digital. The MX Series includes modules from across all Microchip embedded controller families, and provides a common mechanical and electrical interface. The modules are suitable for a rapid-development environment, but are also engineered to be used in a production environment. The MX PIC24F EDU Module (STR001) is specifically designed for this lab. The main processor on this module is the Microchip PIC24FJ256GB110. This 16-bit controller has 256 Kb of internal flash memory and many useful peripheral modules. Each lab will explore various aspects of this controller. The MX PIC24F EDU Module also includes the PICkit on-board circuit that allows the board to connect to MPLAB IDE with only a standard USB cable. The debugging and programming resources normally found in an external PICkit 3, MPLAB ICD 3, or MPLAB REAL ICE in-circuit emulator are included on board for an optimal development environment. All labs require the MX PIC24F EDU Module to be inserted into the MX Educational Target Board (STR002). The MX Educational Target Board provides the power and I/O required by the MX PIC24F EDU Module. This board connects the various I/Os of the module to easy-to-use interface connectors including RS232 DB9 connectors, a breadboarding area, and common headers for other electrical busses. The MX Series is intended to provide an infrastructure that will allow the user to quickly develop their application on a known-good hardware platform. The commercial modules come with on-board Ethernet and USB (device, host, and on-the-go), as well as various options for external memory. In addition, template projects are provided for MPLAB IDE that include fully working TCP/IP and USB stacks along with demo applications. Only the custom firmware required for the specific application needs to be added. Note: Although the labs presented here are based on the MX Module series manufactured by Stratford Digital, they can easily be implemented on a variety of other development platforms from Microchip and third parties with minor modifications. Many of the labs are also applicable to other 16-bit Microchip products, including the PIC24H, dsPIC30F and dsPIC33F. For more information, visit www.microchip.com/academic.

0.1 OBJECTIVE 0.2 PRE-LAB Lab 0. Introduction to Microcontrollers LABS This lab is an introduction to the following concepts required to complete the labs: • MX PIC24F EDU Module • Microchip PIC24FJ256GB110 MCU • 16-bit MCU Assembly Instruction Set • Microchip MPLAB IDE Software v8.63 0.2.1 Reference Material • PIC24FJ256GB110 Family Data Sheet (DS39897) • 16-Bit MCU and DSC Programmer’s Reference Manual (DS70157) • MPLAB IDE User’s Guide (DS51519) 0.2.2 Assembly Language All labs will be written in assembly language. Assembly language is a low-level language for programming computers, microprocessors, and microcontrollers. It is specific to a particular device or family of devices and is not typically portable between different processors. A utility program called an assembler is used to translate assembly language into the target hardware machine code. These labs will use Microchip's MPLAB ASM30 assembler to generate machine code for the PIC24FJ256GB110. Assembly language uses simple instructions, symbols, and numeric characters usually defined by either the assembler utility or the device hardware manufacturer. The assembler then performs a translation from the mnemonic assembly statements into hardware specific machine instructions and data. The machine instructions can then be programmed into the controller's memory and executed on the specific hardware. The “16-bit MCU and DSC Programmer's Reference Manual” (DS70157) from Microchip is a complete list of all assembler instructions for the Microchip 16-bit processor family, including the PIC24FJ256GB110. A further suggestion from Microchip: Microchip Technology Inc. strongly suggests a .s extension for assembly source files. This will enable you to easily use the C compiler driver without having to specify the option to tell the driver that the file should be treated as an assembly file. See the “MPLAB C Compiler for PIC24 MCUs and dsPIC DSCs User's Guide” (DS51284) for more details on the C compiler driver. 0.2.3 Timing The project initializes the PIC24FJ256GB110 to run from its internal Fast RC oscillator. It configures the use of the internal PLL to create an internal clock running at 32 MHz (Fosc). The architecture of the PIC24 specifies that an instruction cycle (Fcy) is com- 2011 Microchip Technology Inc. DS51963A-page 7
