As the name indicates, Baseboard acts the base of the PICKIT. It works as the support board for other boards. The port connections from PIC Board are distributed through Baseboard. It also contains 16×2 character LCD, Graphic LCD, and keypad.
The keypad is 4×4 matrix type and has 8 pins to connect with PIC Microcontroller, so it will use an 8-bit port for interfacing. The keypad can be used in both pull up and pull down mode. J18 is the Keypad Port connector and it should be connected to any one of the port connectors. J34 selects pull up and pull down mode.
The PIC KIT has a two-line character LCD and needs two ports for its operation. J24 (LCD port 1) and J23 (LCD Port 2) are two LCD ports and can be connected to the default port J36 (Port D) and J37 (Port A).
The switch SW1 should be turned ON for using the character LCD. The potentiometer can be used to adjust the contrast of the display.
The graphical LCD has a 128×64 resolution and can be used to display monochrome images, custom texts in different fonts etc. Graphical LCD uses two ports, J41 and J42. By default, we can connect it to J43 (Port D) and J44 (Port A).
The switch SW2 should be turned ON to use the Graphical LCD.
The breadboard is useful for wiring and connecting small circuits and sensors to the PIC KIT. All port headers are available around the breadboard, so it is easy to connect to any port from the breadboard.
This is a bunch of most used port pins of PIC Microcontroller. These ports ease the process of interfacing external modules. Modules available through special ports are SPI (J45), I2C (J19), UART (J35), Analog (AN0), PWM and External Interrupt (INT) pins with power & ground.
