Message Pump using PIC16F687 microcontroller

Brief: The Message Pump A.K.A. the USB to LCD Backpack is a device that allows you to connect a LCD display directly to your computer. It uses a PIC micro-controller, to drive the LCD and a FTDI USB to serial chip to connect to your computer. The great thing about the FTDI chip is that it’s drivers are available for Macintosh, Windows, and Linux! The FTDI chip works by creating a VCP (virtual com port) and ...

LCD interface with Microcontroller PIC: Beginner’s guide using pic microcontoller

How to interface LCD (Liquid Crystal Display) display module to PIC microcontroller? LCD is a passive component, that is it does not make any light but just modifies the light passing through it for alphanumeric displays. LCD is exclusively manufactured to be used with microcontrollers, which means that it cannot be triggered by usual IC circuits. This embedded program shows how to connect PIC to LCD displa ...
