Introduction
Advertising is the most common and important thing for a product, service, or any feature you want to sell. The common way to advertise is to make banners, hoardings, paintings, etc. But now a day’s digital display is also getting popular to display advertisement, because of their durability, and customization feature. You can set text, display images and even you can play a video on the display. These boards are a little costly but due to their features, it’s gaining a place in the market. In this tutorial, we will interface a red 32×16 dot matrix display (DMD).
The size of the P10 display is 6 inches in height and 11 inches in width. The display contains a total of 512 LEDs. LED color varies according to your purchase. Here I am using a RED DMD display.
Using the P10 display you can build any size of display for your advertisement board. These display boards are IP65 waterproof.
Specification of P10 display:
- Brightness – up to 5000
- Maximum power consumption – 20watts
- IP65 waterproof.
- Pixel configuration – 10mm
P10 display pin descriptions:
- Pin 1(OE)- is the enable pin and is used to control the brightness of the panel.
- Pin2 (A) and Pin3 (B) are the two selection line to select from multiple rows.
- Pin8 (CLK), Pin10 (SCLK), and Pin12 (DATA): are the control pins of the shift register.
