FIGURE 4-1: DEVICE PROGRAMMER DIAGRAM
4.3.2 PC Software
The programming circuitry is controlled by a host PC application through the DB25
connector. The PC application is a graphical interface that allows the device to be
quickly and easily configured with the user defaults. Figure 4-2 shows the main screen,
which is used to navigate to all of the MCP250XX device peripherals that can be
configured with the defaults.
The other screens, as shown in Figure 4-3 thru Figure 4-7, are used to configure all
peripherals. Together, both the hardware and software use the ICSP methodology as
described in the MCP250XX programming specification.
The software has the ability to save user defaults into IHEX8 format, which can be
imported to the PRO MATE II device programmer through MPLAB
®
IDE for
programming the MCP250XX devices.
