(2) A Arduino UNO R3 board or Arduino Mega2560 board.
3.2 tft lcd arduino tutorial driver#
Provide underlying driver technical support.Provides an Arduino library with a rich sample program.On-board 5V/3.3V level shifting IC, compatible with 5V/3.3V operating voltage.
3.2 tft lcd arduino tutorial serial#
8-bit parallel bus, faster than serial SPI refresh.Support 16-bit RGB 65K color display, display rich colors.with SD card slot, the SD card supports UNO and mega2560 booard.480X320 resolution,support for touch function.Compatible with Arduino UNO and Mega2560, and can be connected directly by inserting the pin into the interface without wire.Serial.print(0x7E) Serial.OSOYOO 3.5 inch touch screen is designed to work with Arduino UNO/Mega2560 board. MySerial.write(0x7E) // Starting byte, is always the same. PROGMEM const byte resetTFT = // If necessary, clear old messages from the serial buffer. All commands for the TFT should start with 0x7E, but to save storage space this is taken care of in the basicCommand function. Signed int touchY = 0 // Touch screen position Y Signed int touchX = 0 // Touch screen position X
#define MAX_BASIC_COMMAND_LENGTH 20 // How many bytes are in the longest basic command?īyte receivedChars // An array to store the received serial dataīoolean touched = false // Was the touchscreen just touched?

* This code is provided 'as-is', and may be considered public domain. * This is a small bit of messy demo code for the Open Smart serial touchscreen. Users expect touch interfaces, and the cost is not much higher than other input hardware. If you want to display a single character, this means you have to display the character and 4 space commands.Īll in all though, I'm very happy with it.
