D1 Mini NodeMCU ESP-WROOM-32 to ili9341?

Howdy.

Just bought this ESP32 D1 Mini:

Trying to connect it to a 2.8 inch ili9341.

Are there any good instructions for this?

This seems like the pinout:

and this seems like a good connection map:

D1 mini GPIO Shield D1 Pro
NC*(D1/D2/D3/D4) NC*(5/4/0/2) TFT_LED 21
RST*(D1/D3/D4)) RST*(5/0/2) TFT_RST 22
D8 15 TFT_DC 05
D7 13 MOSI 23
D6 12 MISO 19
D5 14 SCK 18
D0 16 TFT_CS 26
D3*(D1/D2/D4) 0*(5/4/2) TS_CS 17

I get the screen to power on but can't yet write to it.

I set up an esp32 DEVKITC to the screen just fine.

Any thought appreciated.
