I'm running on an ESP32 btw. Just like your youtube video, similar wiring but not the exact same

from arduino_gfx.

multiple libraries were found for "Arduino_HWSPI.h" means you have 2 or more versions of Arduino_GFX library folders, please remove all of them and download latest one again.

from arduino_gfx.

@moononournation does the latest one still reference unity.h?

I found this import can be removed, as I had the same error:

'''
C:\Users\nicol\OneDrive\Documents\Arduino\libraries\Arduino_GFX-master\Arduino_ESP32SPI_DMA.h:19:19: fatal error: unity.h: No such file or directory
'''

from arduino_gfx.

unity.h was added to arduino-esp32 on 27 Nov 2018: espressif/arduino-esp32#2108

Please update the arduino-esp32, some forum discussed how to do that: https://esp32.com/viewtopic.php?t=8284

from arduino_gfx.

I only have one arduino_gfx and I also have the latest version of esp32... (1.0.4)
Could it be interfering with another library?

from arduino_gfx.

I do get the same error on platformio and using only arduino_gfx library, so it cant interfer with anything else...

from arduino_gfx.

I have tried compile your code in above post with Arduino IDE 1.8.13, latest Arduino-esp32 and Arduino-GFX master branch. Every things goes well if I commented out #endif at line 115.

Sketch uses 234111 bytes (17%) of program storage space. Maximum is 1310720 bytes.
Global variables use 13596 bytes (4%) of dynamic memory, leaving 314084 bytes for local variables. Maximum is 327680 bytes.

from arduino_gfx.

So I just followed uvwxy advice, which was to comment out the #include "unity.h" and it fixed my problem... which isnt a real solution but that will be enought for me... (I had every latest versions of everything) so thats weird

from arduino_gfx.

I think you should locate why the compiler cannot find "unity.h" that should included in arduino-esp32. Or you will encounter further wired problems while development.

from arduino_gfx.

@moononournation I think you are absolutely right.

I still have one question: for what is the unity.hneeded in Arduino_ESP32SPI_DMA.h?

I know removing it might not be the correct approach. But it still worked. Question is: why?

from arduino_gfx.

unity.h should only be used while unit test. But now I know it have a side effect that can prevent you using arduino-esp32 before 27 Nov 2018 ;P
