Hi – would like some help with a 2.8” LCD Shield HX8347, have been using MCUFRIEND library. When I upload any of the examples all I get this the error not able to upload to board, the only one I get to upload is the LCD_ID_readreg file and these are the results :

Have tried uncommenting the drivers in the .cpp file, and am using a mega \ uno with the same results.
Many thanks
From C:\Users...\Documents\Arduino\libraries\Mcufriend_kbv\extras\mcufriend_how_to.txt
10. It currently supports UNO shields with "mcufriend.com" pcbs with controllers:
...
HX8347-I 240x320 ID=0x9595 #define SUPPORT_8347D
...
Most of these controllers are #define SUPPORT_xxxx by default.
You can save Flash memory on a Uno by commenting out the macro(s) in MCUFRIEND_kbv.cpp
Edit MCUFRIEND_kbv.cpp to enable #define SUPPORT_8347D
Plug the Shield into Uno, Mega, Zero, ...
Run all the examples.
David.
Hi there - Many thanks for you help, added #define SUPPORT_8347D, but no change, would not upload any of the example expect LCD_ID_readreg and LCD_ID_readnew ....

I don't believe you.
Run diagnose_TFT_support.ino from the examples.
Copy-paste the Serial Terminal to your message here.

Hi David - thanks for your help - no joy with diagnose_TFT_support got the following error message;
C:\Users\gu284\OneDrive\Documents\Arduino\libraries\Adafruit_GFX_Library\Adafruit_GrayOLED.h:30:10: fatal error: Adafruit_I2CDevice.h: No such file or directory

many thanks
Just checked that I have got the Adafruit_GFX_Library installed and I have..
Run the IDE Library Manager.
Make sure that your libraries are up to date. Adafruit often updates files.
Those files are not actually needed by MCUFRIEND_kbv but Adafruit installs them anyway.
David.
Great - got it working many thanks, re-installed Adafruit_GFX_Library and got it working.
Thank you.
Thanks for yor help, where does one buy you the vitural pint ?
