100mm 7 segment display
I want to drive 3 digit 7 segment display. My purpose is, the data which received from computer, show in display. I have developed the circuit and firmware for PIC so that it. I can drive the small display with this circuit that powered 5V in a board. But I can't do it for 100mm display. When I give 9V voltage to the circuit, 100mm display works correct and brightness of display is good. Also ICs are not be warm.
But my problem is I know that ST232 ve PIC16f628 should worked with max 5.5-6V voltage. In this conditions, in long time range, Have I problem with this circuit? And Is there a way for this circuit works with 5V voltage.
Thanks.
