Reviewed the TFT_text and found nothing related to blinks (see the video in - YouTube).Īnother detail when I change cd4050 for resistors the screen does not work. The Arduino Mega board has a total of 54 digital input/output pins, 15 pulse-width modulation (PWM) pins, 16 analog inputs, and 4 serial communication ports. This diagram provides a visual representation of all the pins on the board and their functions. So I tried to use the TFTv2 did not work. Pinout Diagram: To understand the Arduino Mega board, it is essential to know its pinout diagram. I put the sketch TFT_text (see below the code and TFT.h and TFTv2.h) and it worked, but the screen flickers(flashes quickly as if the arduino pin resetting) and the image is mirrored. I looked at the links you showed me and did exactly as you suggested, put a CD4050 and tested before the other sketch already worked with the resistors. LCD_Write_COM(0x26) //Gamma curve selected It is a suggested board for 3D printers and robotics. By checking where the Arduino DUE SPI pins are located on the pinout scheme I found these errors or presumed to be such for me: It is indicated on the double Digital pins D50-D53 as SPI but this does not appear in the wiring diagram. It has 16 analog pins and a big space for your sketch. From that 54 digital pins, 15 pins can be used as PWM outputs. It has 54 digital I/O (input/output) pins. It is mainly for more complex and larger projects. LCD_Write_COM(0xF2) // 3Gamma Function Disable Arduino MEGA 2560 is an extended version of Arduino UNO. LCD_Write_COM(0xB6) // Display Function Control LCD_Write_COM(0x36) // Memory Access Control P_CS = portOutputRegister(digitalPinToPort(LCD_CS)) P_RST = portOutputRegister(digitalPinToPort(LCD_REST)) P_DC = portOutputRegister(digitalPinToPort(LCD_DC)) P_MOSI = portOutputRegister(digitalPinToPort(LCD_RS)) P_SCK = portOutputRegister(digitalPinToPort(LCD_WR)) Volatile uint8_t B_SCK, B_MOSI, B_DC, B_RST, B_CS Volatile uint8_t *P_SCK, *P_MOSI, *P_DC, *P_RST, *P_CS With this information, let us now see the pin description of Arduino Nano. On the other side, D13 is Pin 16, 3V3 is Pin 17 etc. So, TX is Pin 1 RX is Pin 2, RST is Pin 3 and so on. Let the numbering begin with the TX Pin (D1). #define LCD_REST 12 //RESET - PINO 4 DO TFT For pin description of Arduino Nano, let us assume some basic numbering. USAR O PINO 8 DO TFT PARA DETERMINAR O BRILHO DO DISPLAY Arduino Uno and Mega have a pin at 3.3V but all other pins are at 5V. Although I tried it but no luck, that if 3V is required, can it be done with mega Arduino Mega Also on Arduino Mega signals on pins are at 5V. I havent been able to get this 2.2' display to work either. Just for ElecFreaks TFT01-2.2SP, which use SPI serial port and 240x320 pixel. I purchased a 1.8' (got working) and this 2.2' tft display from eBay. The LCD connection is the same as Nokia LCD5110 and is a? Bit Pant Demo? I tried to use the librarie suggested by chisco and pinout suggested by nid69ita and then the TheCoolest and none of them worked. Friends, I have a TFT with 2.2SP ili9341 (even that has nid69ita) working on nano and I can make it work with the sketch below (using 22k resistors instead of using cd4050).
