I have a problem! I want to calibrate my touch screen with UTouch
so I have the correct coordinates for the Ferduino controller.
But it is harder than I thought! I've tested countless libraries now. My board has 480x320 picel labeled
ILI9481 a 3.5 "display
should work with TFT_HX8357 but nothing happens
I can not do it!
The only calibration that works is from MCUFRIEND_kbv
called Touchscreen Calibration Native
Test result:

cx=172 cy=926 cz=180 LEFT, TOP, Pressure
cx=168 cy=921 cz=201 LEFT, MIDH, Pressure
cx=150 cy=117 cz=592 LEFT, BOT, Pressure
cx=521 cy=940 cz=268 MIDW, TOP, Pressure
cx=152 cy=921 cz=201 MIDW, BOT, Pressure
cx=877 cy=937 cz=420 RT, TOP, Pressure
cx=880 cy=530 cz=535 RT, MIDH, Pressure
cx=884 cy=109 cz=661 RT, BOT, Pressure
MCUFRIEND_kbv ID=0x9486  320 x 480

const int XP=8,XM=A2,YP=A3,YM=9; //320x480 ID=0x9486
const int TS_LEFT=139,TS_RT=903,TS_TOP=946,TS_BOT=370;
PORTRAIT CALIBRATION     320 x 480
x = map(p.x, LEFT=139, RT=903, 0, 320)
y = map(p.y, TOP=946, BOT=370, 0, 480)
Touch Pin Wiring XP=8 XM=A2 YP=A3 YM=9
LANDSCAPE CALIBRATION    480 x 320
x = map(p.y, LEFT=946, RT=370, 0, 480)
y = map(p.x, TOP=903, BOT=139, 0, 320)

The TFT display is plugged directly onto my Arduino Mega
on the pins
A0-A4 GND- 5V- 3.3V reset
PWM 2-PWM12

Properties: //what i've buy
This TFT-LCD screen module with LCD break, SD card and Flash design. So it's a powerful extension module for your project.
Dimension: 3.5 inches
Controller: ILI9481 or ILI9488 driver (default random) //only ILI9481 works but not in UTOUCH
Resolution: 480x320
Data bits: 8 - 16
Interface pin number: 37 pin
Distance: 1 mm

This pin arrangement does not work!

In The Touchscreen Calibration Native is only

#include <MCUFRIEND_kbv.h>
MCUFRIEND_kbv tft;[/codebender]

In many Sketches the Pins are correct but nothing happens
display stays white

#define LCD_D3 3

#define LCD_D7 7


I hope somebody can help me to integrate my display.
I still have a 3.2 "display but I have not worked on it yet.
I would like to first get the 3.5 "display to run

Hi!

Sorry, this model is not compatible with Ferduino and this model is not in my part list. So I can't help you.
Please do not PM me for support unless it is absolutely necessary.

I'll not write custom function to nobody unless you can pay for my job.

Can you told me some touchscreen 3,5“ or i know must fit in code 7,0“ that is compatible with uTouch and UTFT that I can buy to run Ferduino Aquarium Controller

I've an Pin settings for my ILI9486 3,5" Ilitek Touchscreen in UTouch Calibration
to fit for Ferduino Code

UTouch  myTouch(31,32,33,34,35);


Pin Settings put to Analog A0-A4
LCD_RS = A2
LCD_WR = A1
LCD_CS = A3
LCD_RST = A4
LCD_RD = A0

Pin Settings put to Digital D30-D37
LCD_D2 = D35
LCD_D3 = D34
LCD_D4 = D33
LCD_D5 = D32
LCD_D6 = D31
LCD_D7 = D30
LCD_D0 = D37
LCD_D1 = D36

5V = 5V
3,3V = 3,3V
GND = GND

When I upload Utouch Calibration display stay white nothing happens
what is my mistake what is the correct pin setting for my Display
I use many different Settings for pins but still white no calibration

Hi!

As I told this TFT is not in my part list and is not compatible with my code. There's no support for this hardware here.

Also you can buy a TFT 5" or 7" with resolution 800 x 480 and controller SSD1963 but you should edit the code by yourself.

Best regards.
Please do not PM me for support unless it is absolutely necessary.

I'll not write custom function to nobody unless you can pay for my job.
