Does PRESTO work with MPLAB (PICC, AVR Studio, ...)?

There are two answers - NO and YES:

NO - PRESTO cannot appear in MPLAB "Programmers" menu. We got the MPLAB interface description from Microchip but we decided not to add our software directly to the MPLAB environment due to some important reasons. We may change our minds in the future but we don't plan it at this moment.

YES - there is no problem in today's multitasking operation systems to work with more simultaneously launched applications. Software UP supports its use with any other system producing the HEX output files - like Microchip MPLAB, Hi-Tech PICC, AVR Studio or any other compiler. When our software detects that the HEX file has changed, it reloads the new file automatically (of course, this feature can be disabled by the user). Then you can simply press the GO button on PRESTO or launch the programming from the UP (by using mouse or programmable keyboard shortcut). Moreover, UP can be efficiently controlled from the command line or using Windows messages.
