I need to sniff some legacy SPI hardware and at hand have a Pickit3 and lots of PIC18F2550/4550.
While there is no project out there that builds a logic analyzer out of a PIC18F2550/4550 (I will be glad if you suggested one), I can see that using the PICkit3 scripting tool (PICkit3_GUI_scripting_v03.00beta) it could be possible to run the PK2 logic analyzer feature on the PK3.
Unfortunately, Microchip does not seem to have taken that software forward, nor do I see anyone writing about it.
- has anyone actually used the PICkit3 scripting tool (and specifically the logic analyzer feature)?
- are there any "good" DIY logic analyzer projects out there that use the PIC18F2455/2550/4455/4550 family?
