Multi-Interface LCD

MI-LCD is a multiple interface: DBI Type B Parallel Interface (intel 8080), DBI Type C Serial Interface (3-wire SPI) and DPI Interface ( RGB) 5 inch TFT LCD capacitive touch screen module which is compatible with teraisc DE-series boards

Features

• 5 inch TFT LCD with 480(RGB)*854(line)
• capacitive touch screen with 5 points touch
• ili9806g and ft5x16 chips
• similar to terasic MTL2 and LT24 (two in one)
• support DBI Tpye B display interface (Intel 8080 8-bits,9-bits,16-bits,18-bits,24-bits bus)
• support DBI Tpye C display interface (3-wire SPI)
• support DPI display interface (RGB), 16/18/24-bit Pixel Format with SPI initialization
• support touch i2c inferface
• teraisc DE-series boards 2x20 GPIO Pins
• Arduino Pins with Intel 8080 8-bits bus and touch i2c
