When I look at bigger displays it looks like this:
- From display - to NodeMCU:
GND - GND
VCC & BLK (optional) - 3V3,
SCL - D5
SDA - D7
RES - D2
DC - D1
CS - D8
Is this the right way? Second question: do I need to declare the pins when starting to code in Arduino?
For now i want the most simple program to show just a line or some text on screen.
Thanks in advance. Any help will be appreciated.
