7 Segment Display Interfacing with PIC Microcontroller
7 Segment Display Interfacing with PIC Microcontroller EMBEDDED 12 7 Segment Display Interfacing with PIC Microcontroller This is our 8th tutorial of Learning PIC microcontrollers using MPLAB and XC8 . We have come up all the way from installing MPLABX to using a LCD with PIC MCU. If you are new here, then look at previous tutorials where you can learn timers , blinking LED , interfacing LCD etc.. You can find all our PIC Tutorials here . In our last tutorial we saw how we can generate Custom characters with our 16*2 LCD display , now let us equip our self with another type of display module called the 7-segment display and interface it with PIC Microcontroller . Although 16x2 LCD is much more comfortable than 7-segment display but there are few scenarios where a 7-segment display would come in handier than a LCD display. LCD suffers from the drawback of having low character size and will be overkill for your project if you are just planning to di
