Software Tools for Easy Debug and Development:

DSP and Math Libraries and Advanced Debug

dsPIC DSP Library

The dsPIC DSP Library provides a set of speed optimized

functions for the most common digital signal processing

applications. In total, 49 functions are supported by

the DSP Library. It is part of the 16-bit Language Tools

Libraries. The DSP Library provides significant performance

savings over equivalent functions coded in “C” and allows

developers to dramatically shorten their development time.

The functions are callable from both ‘C’ and Assembly.

Fixed Point Math Library for PIC24 MCUs and

dsPIC DSCs

The I/Q Fixed Point Math Library provides a set of speed

optimized functions for the most common digital signal

processing applications. This library provides significant

performance savings over equivalent functions coded in C and

allows developers to dramatically shorten their development

time. The I/Q math library includes over 65 general-purpose

functions composed of 28 functions supporting Q15 math

and thirty seven functions supporting Q16 math. The IQ math

functions are callable from both ‘C’ and Assembly.

Floating Point Math Library for PIC24 MCUs and

dsPIC DSCs

The IEEE-754 Compliant Floating Point Math Library is the

compiled version of the math library that is distributed with

the highly optimized, ANSI-compliant MPLAB XC16 C Compiler.

It contains advanced single and double-precision floating-point

arithmetic and trigonometric functions from the standard C

header file <math.h>. The library delivers small program code

size and data size, reduced cycles and high accuracy.

Real-Time Data Monitor (RTDM)

The Real-Time Data Monitor

saves development and

testing time for embedded

control applications. RTDM

allows users to make

a change to a software

parameter and see the

effect immediately without

stopping the application execution. A serial USB or UART

cable supports bi-directional data transfers between the

host PC and the MCU/DSC.

Data Monitor & Control Interface: A Free

MPLAB X IDE Plug-in

The Data Monitor and Control Interface (DMCI) provides

dynamic access and control of software variables. It is

useful for tuning application parameters and viewing run-time

application data graphically. Software parameter changes are

updated during run-time. Feature highlights include:

variables are recognized automatically by DMCI

of application data

MATLAB Device Blocks for MPLAB X 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 X IDE. Also provided are many

examples in the form of demo models, including a complete

BLDC motor control application.

dsPICworks™ Data Analysis and DSP Software

The dsPICworks Data Analysis and DSP Software makes it

easy to evaluate and analyze DSP algorithms. You can run

a variety of DSP and arithmetic operations and analyze your

data in both time and frequency domain.

Digital Filter Design Tool

The Digital Filter Design Tool makes designing and

analyzing FIR and IIR filters easy. Enter frequency

specifications and filter code and coefficients are

generated automatically. Graphical output windows provide

the desired filter’s characteristics.
