This LCD expansion board removes all the complications and risks. The TELEMATICS 3.5" TFT Touch LCD Shield is an Arduino compatible display designed by DFRobot, with a resolution of 320x480, three serial ports and one IIC interface. It is perfectly compatible with Arduino DUE, Mega1280/2560, and Bluno Mega1280/2560. There is an on-board voltage switch which supports changing the output voltage between 3.3V and 5V to ensure that it won't damage your DUE. In addition, the LCD shield comes with a MicroSD card slot on the back that can be used for data storage up to a maximum of 32GB. We also offer a variety of driver packages to help you implement different features. Note: Since the operating voltage of DUE and MEGA are different, the backlight brightness will change if you replace your Arduino platform. Please adjust the D8 PWM signal to control the brightness of the backlight Specification              Screen Size: 3.5" Resolution Ratio： 320x480 Power Supply: 5V Output Voltage: 3.3/5V Backlight Control Mode: D8 PWM signal Supports MicroSD card (Up to 32GB) Serial Ports: 3 IIC interface: 1 Compatible with Arduino Compatible DUE/Mega 1280/2560 Compatible with the Bluno Mega 1280/2560 Supports Touch Functionality Dimensions: 100x57mm/3.93x2.24 inches Weight: 70g Board Overview InterfaceDescription Note:  LCD Driving Pins: D2, D3, D4, D5, D6, D8, D22~D41, D50~D53 IIC Interface IIC (SDA: 20; SCL: 21) Serial1 Serial1 Serial2 Serial2 Serial3 Serial3 D52>DATA0 SD D50->CMD Driving D52->CLK Pins D53>CD/DATA3 Tutorial Requirements   Hardware Bluno Mega 2560 x 1 TELEMATICS 3.5" TFT Touch LCD Shield x 1 Software Arduino IDE (Latest) Click to Download Arduino IDE from Arduino® Download related Libraries. How to install libraries https://www.arduino.cc/en/Guide/Libraries#.UxU8mdzF9H0 Sample Code 1 In this section, we'll explain how to initialize the LCD screen. You can use "setFontSize" and "setColor" function to change the font and the color of the characters 1 /* 2 This code will demonstrate how to make the LCD display string with the library 3 If you need to set the font size, you can call this function "setFontSi ze()",and you can set the parameters: 4 FONT_SIZE_SMALL 5 FONT_SIZE_MEDIUM 6 FONT_SIZE_LARGE 7 FONT_SIZE_XLARGE 8 9 If you want to set the font color, you can call this function "setColor ()" with the parameters: 10 RGB16_RED-------->RED 11 RGB16_GREEN------>GREEN 12 RGB16_BLUE------->BLUE 13 RGB16_YELLOW----->YELLOW 14 RGB16_CYAN------->CYAN 15 RGB16_PINK------->PINK 16 RGB16_WHITE------>WHITE 17 18 19 20 Created 2016-4-8 21 By Andy zhou 22 version:V1.0 23 */ 24 #include 25 #include 26 #include 27 28 LCD_R61581 lcd; 29 30 void setup(){ 31 lcd.begin(); 32 lcd.setFontSize(FONT_SIZE_MEDIUM); 33 lcd.setColor(RGB16_RED); 34 lcd.println(); 35 lcd.println(); 36 lcd.println("DFRobot!!!"); 37 lcd.println("TELEMATICS LCD SHIELD V1.0"); 38 lcd.println(); 39 lcd.setColor(RGB16_WHITE); //set font size //set strings color 40 } 41 42 void loop(){ 43 } Sample Code 2 In this section, we'll explain how to use the SD card with LCD screen. 1 /* 2 /* 3 This code is to teach you how to use SD library. 4 5 Created 2016-4-8 6 By Andy zhou 7 version:V1.0 8 */ 9 #include 10 #include 11 #include 12 #include 13 #include "datalogger.h" 14 15 #define STATE_SD_READY 0x1 16 #define STATE_OBD_READY 0x2 17 #define STATE_GPS_CONNECTED 0x4 18 #define STATE_GPS_READY 0x8 19 #define STATE_MEMS_READY 0x10 20 #define STATE_GUI_ON 0x20 21 22 LCD_R61581 lcd; 23 CDataLogger logger; 24 25 byte state = 0; 26 27 bool checkSD() 28 { 29 Sd2Card card; 30 SdVolume volume; 31 state &= ~STATE_SD_READY; 32 pinMode(SS, OUTPUT); 33 34 lcd.setFontSize(FONT_SIZE_MEDIUM); 35 if (card.init(SPI_HALF_SPEED, SD_CS_PIN)) { 36 const char* type; 37 switch(card.type()) { 38 case SD_CARD_TYPE_SD1: 39 type = "SD1"; 40 break; 41 case SD_CARD_TYPE_SD2: 42 type = "SD2"; 43 break; 44 case SD_CARD_TYPE_SDHC: 45 type = "SDHC"; 46 break; 47 default: 48 type = "SDx"; 49 } 50 51 lcd.print(type); 52 lcd.write(' '); 53 if (!volume.init(card)) { 54 lcd.print("No FAT!"); 55 return false; 56 } 57 58 uint32_t volumesize = volume.blocksPerCluster(); 59 volumesize >>= 1; // 512 bytes per block 60 volumesize *= volume.clusterCount(); 61 volumesize >>= 10; 62 63 lcd.print((int)volumesize); 64 lcd.print("MB"); 65 } else { 66 lcd.println("No SD Card"); 67 return false; 68 } 69 70 if (!SD.begin(SD_CS_PIN)) { 71 lcd.println("Bad SD"); 72 return false; 73 } 74 75 state |= STATE_SD_READY; 76 return true; 77 } 78 79 void setup(){ 80 lcd.begin(); 81 lcd.setFontSize(FONT_SIZE_MEDIUM); 82 lcd.setColor(RGB16_RED); 83 lcd.println(); 84 lcd.println(); 85 lcd.println("DFRobot!!!"); 86 lcd.println("TELEMATICS LCD SHIELD V1.0"); 87 lcd.println(); 88 lcd.setColor(RGB16_WHITE); 89 if (checkSD()) { //set font size //set strings color 90 uint16_t index = logger.openFile(); 91 lcd.println(); 92 if (index > 0) { 93 lcd.print("File ID:"); 94 lcd.println(index); 95 } else { 96 lcd.print("No File"); 97 98 } } 99 } 100 101 void loop(){ 102 }  Sample Code 3 In this section, we'll explain how to use the touch function 1 #include 2 #include 3 #include 4 #include "touch.h" 5 6 LCD_R61581 lcd; 7 8 void setup(){ 9 lcd.begin(); 10 lcd.setFontSize(FONT_SIZE_MEDIUM); 11 lcd.setColor(RGB16_YELLOW); 12 lcd.println("DFRobot"); 13 lcd.println("TELEMATICS LCD SHIELD V1.0"); 14 lcd.println(); 15 lcd.setColor(RGB16_WHITE); 16 17 touch.init(); 18 } 19 20 void loop(){ 21 lcd.setCursor(0, 8); 22 int x, y; 23 if ( touch.read(x, y) ){ 24 lcd.print("X:"); 25 lcd.print(x); 26 lcd.print(" Y:"); 27 lcd.print(y); 28 lcd.print(" 29 30 "); } else { lcd.print(" "); //set font size //set strings color 31 } 32 } FAQ For any questions/advice/cool ideas to share, please visit DFRobot Forum.                                     Powered By DFRobot © 2008-2017
