Install instructions do not work for Arduino IDE

[TotallyInformation]

Using the Arduino IDE I followed the instructions in the README but there are some issues:

1. The Button2 library is not in the Arduino library manager, you have to download manually.
2. Then the compile fails with the following errors:

C:\src\arduino\TTGO-T-Display\TTGO-T-Display.ino: In function 'void button_init()':

The Button2 issue was fixed by using the lewishxe version - the link in that repo points to the original which doesn't work.

Now, the remaining error is:

OK, so I'm guessing that the reason it isn't working is that you have referenced a FORK of the actual library instead of the library itself. That fork is 96 commits behind the original!

Why on earth would you do that?

At least make it clear in the README that is what you have done.

[lewisxhe]

Yes, the referenced TFT_eSPI is the branch that I modified after the fork. I should describe it clearly in the readme. Thank you for your reminder.

[lilphil]

It would be a good idea to rebase from the original Bodmer repo. They have renamed the driver, so this patch works against the 1.4.11 release from that repo for the TTGO X Display. Although I'm not sure why it needs to be set as 240 width when it clearly isnt...

Edit: I forgot to mention, you now also need tft.setSwapBytes(true); in the sketch (before tft.pushImage), and it also works for 1.4.13 which is available in PlatformIO

1.4.11-TTGO-T-Display.txt

[TotallyInformation]

@lilphil/@lewisxhe why do we need another fork? Much better to update the original (it has now been updated and should work just fine) than confuse people with another fork that gets out-of-date.

[phillip-toone]

Okay, I am super confused here and have been working on this for hours. Am I supposed to use the linked forks or the original? Neither work for me. The original just gives me errors and linked forks display nothing but the serial monitor shows me that it is working as expected. Also, why are there instructions about moving and modifying files. Shouldn't those details be taken care of in the fork? I don't know how I did it but I once had a display that read "Voltage :4.70" with a small rectangle next to it that seemed to be a shrunk down version of what it used to display on the entire screen what I first purchased it. Also, the pretty graphical TTGO display does not show. Help please.

Check this video on how to install it https://youtu.be/qj9dN-Ginxc

[phillip-toone]

Works! Thanks.

[lewisxhe]

The library used has been synchronized to the main branch

For others that might still be having problems with the screen: If it looks like only 1/3 of the screen is being used, be sure to comment out the default "#include " line of text in the User_Setup_Select.h file that you add the "#include <User_Setups/TTGO_T_Display.h>" line to. Keeping both lines will cause the screen settings to be incorrect. This was not shown in the youtube video linked by FixxCZ, but solved the problem for me.

[flyingdan]

Just worked through the instructions making sure to follow the video and @spradlinb 's suggestion and the image displayed on the screen is half the TTGO image and half the multicolored screen. Here's an image of how it looks

Any thoughts?

UPDATE 2 Ignore the first update and refer to https://github.com/Xinyuan-LilyGO/TTGO-T-Display/issues/4#issuecomment-545962661

UPDATE

Edited the following lines in TTGO_T_Display.h

#define TFT_WIDTH  240 // original: 135
#define TFT_HEIGHT 320 // original: 240

Then in TTGO-T-Display.ino

#define TFT_WIDTH   240 // added
#define TFT_HEIGHT  320 // added

TFT_eSPI tft = TFT_eSPI(TFT_WIDTH, TFT_HEIGHT);  // edited

This got the colors full screen.

The image in bmp.h is too small for a 320x240 display, it's setup for a 135x240 display (32400 bytes).

[ustolt]

In _https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup.h_ must ILI9341_DRIVER be commented out.

// Only define one driver, the other ones must be commented out
#define ILI9341_DRIVER

[tochinet]

iCompiles and upload for me (I trashed the original WiFi library), but nothing on screen, the sketch doesn't even start, and I get this in the Serial monitor :

Rebooting...** and again and again

Actually, it looks similar to the heap problems I 've found on other forums that make the ESP crash in special WiFi cases, but in my case I don't even see the first print statement in setup().

Any idea what could be wrong ? I updated my ESP32 files to 1.0.4 but it doesn't change anything

did you have any errors such this one

Compilation error: bmp.h: No such file or directory

if it is a library i can find it anywhere
