Hi
I just received a Nixie display from Lilygo that is basically an ESP32 with a nice little color TFT display. So far I have been able to manage the display with ESPhome but I have a little issue with the complete sample code given on ESPhome website: ST7789V TFT LCD — ESPHome
I simplified code for my own use and editor doesn’t detect any errors but it fails pretty well at compilation. Any ideas what’s wrong there ?
My sketch:

it.print(0, 0, id(my_font), "Hello World!");
it.strftime((240 / 2), (140 / 3) * 1 + 5, id(my_red), id(my_gray), TextAlign::CENTER, "%Y-%m-%d", id(esptime).now());
it.strftime((240 / 2), (140 / 3) * 2 + 5, id(my_green), id(my_gray), TextAlign::CENTER, "%H:%M:%S", id(esptime).now());
and when I compile what I get as errors:
Library Manager: Installing Hash
