Demo of how the PIC16F84A MCU controls the LCD display
A simulation of a PIC16F84A that controls a scrolling “Bits4Bits” text on a LCD display. The text shifts from left to right until the MCLR pin is grounded in the software by pressing the "spacebar" on the keyboard.
- The PIC reads an 8-bit character from its internal EEPROM.
- The text data must be loaded beforehand by loading an external file named Bits4Bots.mch
- The PIC then sends instructions to the LCD display component to control the text being displayed.
Function: PIC mid-range 8 Bit Microcontroller
If you are building this circuit, set the MCLR pin to VCC (high). The Master Clear pin is an optional external reset that is activated by pulling the pin low. During normal operation, it needs to be pulled high typically through a resistor to VCC.
