Programming with mikroProg™ programmer The microcontroller can be programmed with mikroProg™ programmer and mikroProg Suite™ fo PIC® software. The mikroProg™ programmer is connected to the development system via the CN6 connector, Figure 3-12. mikroProg™ is a fast USB 2.0 programmer with mikroICD™ hardware In-Circuit Debugger. Smart engineering allows mikroProg™ to support PIC10®, PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and PIC32® devices in a single programmer.
mikroProg Suite™ for PIC® Software mikroProg™ programmer requires special programming software called mikroProg Suite™ for PIC®. This software is used for programming of ALL Microchip® microcontroller families, including PIC10®, PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and PIC32®. Software has intuitive interface and SingleClick™ programming technology. Just by downloading the latest version of mikroProg Suite™ your programmer is ready to program new devices.
Programming with ICD2® or ICD3® programmer The microcontroller can be also programmed with ICD2® or ICD3® programmer. These programmers connects with mikromedia board via ICD2 CONNECTOR BOARD. Figure 3-15: Connecting ICD2® or ICD3® programmer Figure 3-14: Placing ICD2® connector In order to enable the ICD2® and ICD3® programmers to be connected to the development system, it is necessary to provide the appropriate connector such as the ICD2 CONNECTOR BOARD.
