Re: bbq temperature and meat temperature
Which binary do you use on the Wemos?
I took the one Ath attached to post #93 in this thread. But my display has a different chip (ST7735). Mine:
My display was showing like yours only a white screen, too, until I wired D7 (MOSI) of the Wemos correctly to the DIN of the TFT screen instead of D6 (MISO).
Summary of my wiring:
Wemos -> TFT
D5 -> CLK
D7 -> DIN
D2 -> CS
D1 -> D/C
D4 -> Rst
D8 -> BL

Re: bbq temperature and meat temperature
And you are sure the hardware is ILI9341? Other ILI9xxx types are not always compatible enough to display anything with that configuration, so you could try a build that includes P116, as that also has a couple of extra ILI9xxx configurations available.

it should be ILI9341
are you able to recognize it? i can also post some photos if it can help
do you think that i have to use a different plugin?
Re: bbq temperature and meat temperature
No, it is nearly impossible to identify the chip used, as AFAIK that is integrated on the TFT, and not on the PCB you hold in your hands. The chip you see is probably the touch controller (XPT2046), for which the plugin is also included. You could try that part already, but it needs additional wiring.
Can't explain why it won't work.
