Intronix LogiPort Logic Analyser


My new tool, the logic analyser from, arrived last week.  It was bad timing as I’m in the middle of our house move, however, as I’ve been itching to try it out last night I made time to play with it.  The result is, man I wish I had one of these beasts earlier.

Digging out my Strobit prototype and hooking it up to the SPI bus I was keen to see how it all works (there are a lot of boxes yet to unpack…sob…did I mention that I hate moving house!).

In short I’m impressed with the easy of use of the software and the ability to decode SPI signals on the fly along with I2C, CAN, RS232.

I had the logic analyser reading the SPI signals to and from the RFM12B and all the other signals coming from the RFM12B module.  This bit of kit would have helped tremendously in troubleshooting the PIC and SPI issues I was having at the time
