Hello all, I'm having trouble to use this display on the DUE, I'm only getting the backlight and nothing else, I don't know what to do
LCD specs
http://www.lcdwiki.com/zh/4.0inch_Arduino_Display-Mega2560_NT35510
Thank y'all in advance.
Post the code you tried, in code tags </>
Hello tiagonr
Does the selected display screen match to 3,3volt logic level of the Arduino Due?
Hy Paul, I think so, on the specifications says 5/3.3v
- Support Arduino Mega2560 plug-in use
- 4.0-inch color screen, support 16BIT RGB 65K color display, display rich colors
- 800x480 resolution, clear display effect
- Support 8-bit and 16-bit parallel bus transmission, fast transmission speed
- Onboard 5V/3.3V level conversion IC, compatible with 5V/3.3V working voltage
- Support touch function
- Provide Arduino library and rich sample programs
- Can be used on C51 and STM32 platforms and provide rich sample programs
- Support SD card function expansion
- Military-grade process standards, long-term stable work
- Provide underlying driver technical support
Do you know it precisely?
I've tried all the codes on the examples folder of the lcdwiki, this is one of those
// IMPORTANT: LCDWIKI_KBV LIBRARY MUST BE SPECIFICALLY
// CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.
//This program is a demo of clearing screen to display red,green,blue.
//This program don't need to rely on any libraries and Can run directly.
//Set the pins to the correct ones for your development shield or breakout board.
//the 16bit mode only use in Mega.you must modify the mode in the file of lcd_mode.h
//when using the BREAKOUT BOARD only and using these 16 data lines to the LCD,
//pin usage as follow:
// CS CD WR RD RST D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15
//Arduino Mega 40 38 39 43 41 37 36 35 34 33 32 31 30 22 23 24 25 26 27 28 29
// TP_IRQ MOSI MISO TP_CS EX_CLK
//Arduino Mega 44 51 50 53 52
//Remember to set the pins to suit your display module!

No, I just have the specs I found on lcdwiki
Did you check the logic levels for the hardware ?
How can I check that?
read and check the datasheets of the hardware selected!
