Posted on 16. April 2009 by Lucio Di Jasio

I think I can say we all love the little Memory Usage gauges introduced in MPLAB a couple of years ago.. or was it more? When working in assembly with an 8-bit microcontroller and a couple of Kbytes of FLASH … Continue reading →

Good Old printf()

Posted on 13. April 2009 by Lucio Di Jasio

Good old printf() is probably the oldest debugging tool ever used, I mean beside a light bulb (nowadays replaced by an LED) … yet it represents a pretty sophisticated one when working in a deeply embedded control project. If you … Continue reading →

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 →

UNISON – A POSIX compliant RTOS for the PIC32

Posted on 13. March 2009 by Lucio Di Jasio

Recently I get a lot of questions about Linux on the PIC32…. No, Linux is not available. The main problem is the lack of a true MMU (Memory Management Unit, the PIC32 has only an FMT, fixed mapping table), and … Continue reading →

Tremor

Posted on 5. January 2009 by Lucio Di Jasio

The Xiph.Org Foundation offers an open source alternative to the omni-present MP3 audio compression: it is called Ogg Vorbis and promises same if not better performance but it is royalty-free and license free. From their web site, like in all … Continue reading →

Deep Blue PIC32

Posted on 6. November 2008 by Lucio Di Jasio

An email from Tim O. this week made me think about the possibility of computers conversing with humans, or rather the impossibility of it, as Turing once proposed it as the ultimate test of the machine intelligence.  This in turn … Continue reading →
