What?
- Presenting information in meaningful way is important after generating data using sensors or after passing data to actuators.
- There are several ways to present information using electronic components such as LEDs, 7-Segments, Character LCD Displays and Color TFT LCDs.
- Selection of these components depends on the usecase, amount of information to be displayed and how user want to interact with the component.
- This article explains how can we leverage Full color 3.5” 480 *320 TFT LCD with Arduino UNO, which is one of the component to display the information with required size, font, color and to use the same as touch screen for input.
- TFT LCD Specifications
- LCD Type : TFT
- LCD Interface : SPI
- LCD Controller : ILI9486
- Touch Screen Type : Resistive
- Touch Screen Controller : XPT2046
- Colors : RGB, 65K colors
- Resolution : 480x320 (Pixel)
- Aspect Ratio : 8:5
- I/O Voltage :3.3V/5V
Why?
- From past 16*2 and 16*4 LCD Displays were commonly used to present information using Microcontrollers.
- Disadvantage of these displays are
- Limited space(Need to define character within matrix)
- Limited characters are supported to display
- More configuration to be done for custom characters
- Constant font size
- No color representation
- Full color 3.5” 480 *320 TFT LCD with Arduino UNO overcomes these disadvantages and provides better flexibility to display information.
