Using the 32-bit Core Timer

Posted on 2. April 2009 by Lucio Di Jasio

One of the features of the PIC32 that I have so far somewhat left out in my “explorations” is the 32-bit Core Timer. This is in fact a piece of the MIPS M4K core itself and is common to all … Continue reading →

Testing the PIC32 I/O Speed

Posted on 18. March 2009 by Lucio Di Jasio

In the last several months I have seen a couple of postings on the PIC32 forum about users testing the speed of the PIC32 I/O. It is quite normal and healthy for a community of Embedded Control designers to worry … Continue reading →

Inexplicably Working Errata

Posted on 1. November 2008 by Lucio Di Jasio

A few days ago, I received an email from a reader who reported a new errata on page 123 (in the “Learning to fly the PIC24” book) in the write() function, an example of redirecting the “stdout” output stream. The … Continue reading →

Modifying and Testing the code for the new GA1 and GB1 families

Posted on 7. July 2008 by Lucio Di Jasio

I have received a lot of request recently from readers, future PIC24 pilots, concerning the possibility to port the code from the book to the the newest families of PIC24 microcontrollers. The differences are not that big, but I have … Continue reading →

3D Graphics

Posted on 15. May 2008 by Lucio Di Jasio

Using the new double buffered graphic library (see previous post) we can now create simple animations. In chapter 12 we have already seen how to visualize a 2D function using a grid and a bit of perspective (isometric). The next … Continue reading →

Graphic Animation

Posted on 10. May 2008 by Lucio Di Jasio

In the good old times, when studying at the University of Trieste, I particularly enjoyed Rational Mechanics, a required class for any EE Master back then, presented by professor Enzo Tonti. One of the things that were always making his … Continue reading →

Optimizing the graphic library

Posted on 28. April 2008 by Lucio Di Jasio

While working on the porting to the PIC32 of the code developed for the original PIC24 book it occurred to me that there were some obvious optimizations I had yet to explore. For a starter, the graphic.c library was using … Continue reading →
