ok thanks, but i think i got mine working too now, although i have no idea why didnt it work in the beginning lol.
but the main problem probably comes from the fact that noone filmed the actual pin labels (ss, mosi etc..), so it was really hard to understand what goes where....
but this is what i use on the r2 now when i have i2c sensors(4, 5) also connected - and this ofc took me like 30 hours to figure out completely!!?:z
#define TFT_CS 15
#define TFT_DC 2
#define TFT_RST 16
#define TFT_MOSI 13
#define TFT_SCLK 14
but the test program still crashes tho (after the 4th yellow lines appear), so dunno what is up with that... atleast my other app that i put together myself is working quite fine...

hi
how is it possible that everyone else has no issues with the test program, but my screen just crashes and will not even work on the actual hardware SPI pins at :S
and how should i fix this delay() and yield() thing that someone fixed their problem with?:s
(i have a wemos d1 r2 board)
