Re: As promised, 16-bit dsPIC version of my cheap logic analyzer available
Since this post, I’ve changed processors (dsPIC33EP512MC202) and learned some new coding tricks with the help of the dsPIC forum members. I have 16, 8 and 4 channel working with 30ns/sample in 8 and 16 channel mode. The 3.3V device works with 3.3V and 5V logic and has 3 times the sample memory. The new code, schematic and solderless breadboard photo are at the same link as above. In 4 channel mode, you get over 98,000 samples.
