Using the 32-bit Core Timer
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
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
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
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

Electronica 2008
This is the week of the Electronica 2008 in Munich (Germany) and I am available at the Microchip booth (A4-560) all week to talk about 16 and 32-bit programming but especially about flying! If you are a PIC24 or a … Continue reading
Deep Blue PIC32
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
