Summary of PIC18F4550 USB MARQUEE DISPLAY SCROLLING TEXT CIRCUIT LED VISUALBASIC
Summary: A USB-controlled marquee displays scrolling text sent from a Visual Basic program to an 8×32 LED dot-matrix driven by a PIC18F4550. The PIC firmware was developed with Proton IDE and uses a 74HC154 decoder to drive the LED matrix.
Parts used in the PIC18F4550 USB Marquee Display Scrolling Text Circuit:
- PIC18F4550 microcontroller
- 8 × 32 dot-matrix LED panel (or equivalent LEDs arranged for 8x32)
- 74HC154 decoder/demultiplexer
- USB interface components (USB port and connector)
- Power supply (appropriate voltage regulator and capacitors)
- Resistors for LED current limiting
- Driver transistors or MOSFETs as required for LED rows/columns
- PCB or protoboard and wiring
- Development PC running Visual Basic (to send text)
- Proton IDE (for PIC firmware development)
