I’m preparing to start a new project using a (to me) new mcu (pic32). I will probably need some new debug gear. I noticed the  availability of a RTOSviewer for MPLABx. After googling a while, I could not find which debug tools I can use this viewer with. Microchip has the PicKit3, ICD3 and RealICE. Which of these allow the use of the rtosviewer?

As I recall, the MPLAB 8 viewer could be used with Real ICE, ICD2 and ICD3 - these are the only interfaces I have so I don’t know about anything else.

I’m not sure that the viewer in MPLAB X is completely solid yet, I was given some information on it but I’m afraid I can’t quite remember what.

Thank you for your reply.

Is Real ICE really worth the extra cost above an ICD3? And what about the additional Real ICE accesoires for speed/trace in relation to FreeRTOS?

I’m not really an expert on these things, so take my advice lightly, but for standard debugging I have found the ICD 3 more than capable.  I think the Real ICE is necessary for the more sophisticated tracing on the PIC32 though.

The ICD3 and REAL ICE share the same basic guts.  High Speed USB and the FPGA, so they debug/read/write/program at the same speed.
The ICE adds some features such as the trace and some input/output pins.
But to do really high speed trace you need to shell out more loot for the high speed interface.

ICD3 should be fine for most uses.  The ICD2 is discontinued and it is a bit slow being USB full speed.
