The connection between the MCU main module and the connection module between each peripheral module is concentrated in the module connection area.
Module connection area
There are two upper and lower areas,one of the upper areas has 2 rows of pins,and the lower one has 3 rows of pins,one of the above the second row of pins in the zone (counting from top to bottom) and the second row of pins in the lower zone (from top to bottom) and MCU.
The corresponding pins of the main module are connected,and the remaining rows are connected to the corresponding pins of each peripheral module.
The MCU main module and each peripheral module can be connected to each other in the following two ways:
a, use shorting link, if you use 16F877A, 18F4520, 18F4620, 18F4550 and and they are Pin-compatible PIC microcontrollers, mainly using this connection, they have been preset at the factory 40 short-circuit links,most of the experiments in this tutorial can be completed without changing the preset short-circuit link,a few experiments with one or two or three short-circuit links can be easily done. This type of connection is for learning 16F877A, 18F4520, 8F4620, 18F4550 and their pin-compatible PIC microcontrollers,is the most Convenient.
B, Use a soft jumper. Unplug all 40 short-circuit links preset in the connection area (top) and the connection area(bottom).
Use a soft jumper (also called an experimental patch cord or a DuPont cable) to freely connect the modules.
When you use pinout rules
With the PIC 18F4520, different microcontrollers or 51, AVR microcontroller, this connection is generally used
Connections for all the modules are defined freely by the user, without restriction, has very High flexibility. (Please read the "How to use the development board as a universal burner and how to use the development board."
Different kinds of PIC microcontrollers
Mix and use short-circuit links and soft jumpers. For example, using the 18F4520 development product,you can use a short circuit link. Connecting peripheral modules of existing experimental board, breadboard with a soft jumper connector (also called experimental Plug or Dupont line). There are no peripheral modules built by yourself. The advantage of this type of connection is that the hardware is built quickly and at the same time expansion linking is available.
Connection area short circuit link setting
