Hello there, I am working on a project of automated glasshouse. My system consists of Dragino lora shield with arduino Uno with some sensors for sorrounding environments and I would add a tft ili9341 touch screen as a visualizer for sensors' data. The arduino compiler gives errors, when I add the …

Where in the code do you create the object named tft ?

no ! I did not create it :(, shall I create one. where and how ?

[image] fred189: no ! I did not create it Hence the problem Have you looked at the examples that came with the Adafruit_ILI9341.h library ? They will have a line in them like this Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);

Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO); Thanks alot Sir !! you made my day !! :blush: I have added and it has been solved :slight_smile: ,but I got another error :frowning: concerns to memory full issue Global variables use 1557 bytes (76%)…

Hi, here is the error that I got. for the reviesed code it attached above, I just add a declaration of object. Arduino: 1.8.15 (Windows Store 1.8.49.0) (Windows 10), Board: "Arduino Uno" C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.49.0_x86__mdqgnx93n4wtt\arduino-builde…

Do not attach your code. Post it here in code tags as requested to make it easy to see and copy

here you are. I uncomment some serial print for save some space on memory. sorry for midunderstanding #include <Adafruit_ILI9341.h> /******************************************************************************* * Copyright (c) 2019 Thomas Telkamp and Matthijs Kooijman * * Permission is hereby…

Hello @UKHeliBob , does the code is readable for you ?

I can see the code and I have had a brief look at it but I cannot compile it because I don't have all of the libraries installed, hence cannot investigate the errors and I don't have time to work through the code line by line to see what is going on
