Methods

Emulating Data EEPROM for PIC18 and

PIC24 MCUs, dsPIC DSCs and PIC32

For devices that do not have on-chip EEPROM, emulating

EEPROM with on-chip Flash memory my be an important

option. This application note presents an interface similar

to an internal data EEPROM, but uses available on-chip

Flash memory to improve endurance by a factor as high as

500. (Application Note: AN1095)

Achieving Higher ADC Resolution Using Oversampling

This application note describes oversampling as a method

to add additional bits of accuracy to the 12-bit ADC

conversion in a dsPIC DSC. (Application Note: AN1152)

Bootloader for PIC24 MCUs and dsPIC DSCs

This application note describes a UART-based

bootloader for all 16-bit MCU and DSC families.

(Application Note: AN1094)

A Serial Bootloader for PIC24F Devices

This application note describes a UART-based bootloader

and includes Microchip’s PIC24F Quick Programmer

(P24QP) Windows-based graphical programming interface.

(Application Note: AN1157)

Implementing Digital Lock-In Ampliﬁers Using the

dsPIC DSC

Conventionally, lock-in amplifiers use complicated

(and expensive) analog circuitry to perform the phase

sensitive detection and filtering. However, modern Digital

Signal Controllers (DSCs), such as the dsPIC30F and

dsPIC33F families, can be used to remove large amounts

of the analog circuitry by performing the necessary

operations in software. This capability provides a number

of additional benefits including increased reliability,

resistance to temperature and aging effects, and the

ease with which the system can be modified in the field.

(Application Note: AN1115)

Low Power Design Guide

This document seeks to simplify the transition to

low-power applications by providing a single location

for the foundations of low-power design for embedded

systems. The examples discussed in this document will

focus on power consumption from the viewpoint of the

microcontroller (MCU). (Application Note: AN1416)

Modules

Cyclic Redundancy Code (CRC) Module

CRC is one of the most versatile error checking algorithm

used in various digital communication systems. This

application note illustrates how to use the hardware CRC

module on selected 16-bit MCUs and DSCs. Users can

program any user-defined generator polynomial into this

module for CRC computation. (Application Note: AN1148)

MATLAB Device Blocks for MPLAB IDE

The Microchip Device Blocksets for MATLAB Simulink

provide a set of interface-compliant configuration and run-

time peripheral blocks for the dsPIC30 and dsPIC33 DSCs.

Complete applications can be created in the form of a

MATLAB/SIMULINK model using blocksets provided by

Microchip and Simulink. C code for the application will be

generated. These blocksets are compatible with the MATLAB

plug-in available in MPLAB IDE. Also provided are many

examples in the form of demo models, including a complete

BLDC motor control application.
