[sztamas1990]

Hi,

Can you help me? I dont have a shield yet, but i would like to test your code.
Can you share a wiring diagram with me, how schould i wire the 240x240 TFT panel directly to the Wemos D1 mini?

Thanks for your reply!

Regards,
Tamas

Hmm, I don't have such diagram.

@witnessmenow could you please address this?

Sure!

@sztamas1990 the wiring that I use for the shield is here:

You should be able to just wire a ST7889 module up using the same wiring and the code should work the same

Thanks a lot finally it works!

And I'm facing with another problem: display works well, but coingecko api seems not working.
I receive the following errors on port monitor:

Error connecting to API while downloading base data
-1
Error connecting to API while downloading BTC and ETH data
-1

Can you help me to solve these problems, please?

Thanks a lot!

Regards,
Tamas

Hi,
This may or may not work for you but for me I changed the coingeckoSslFingerprint to "33 C5 7B 69 E6 3B 76 5C 39 3D F1 19 3B 17 68 B8 1B 0A 1F D9" and it started working.

Thank you.
