Interfacing VFD with PIC Microcontroller

Interfacing VFD with PIC Microcontroller

Vacuum fluorescent display can be a good alternative to a Liquid-crystal displays in some applications. They have a number of advantages over LCD like extended temperature range and excellent contrast in high brightness environment. The main disadvantage is higher power consumption making them less attractive in battery operated devices. In this post I’ll show you how
