I have a
2.1 inch
display on theST7701
controllerpinout
I also have an
esp-wroom-32
, its pinout is like thisCan I connect this display to this microcontroller via
3-SPI
?Or only via
4-SPI
orRGB
interface?I found the only file in this library that seems to work with the display controller
ST7701
But here the connection is via the
RGB
interface.The configuration of my equipment that I described above is available to me now.
In general, I have an
esp32-s3-16nr8
and in the future I plan to make a printed circuit board with anRGB
connection, but now I wanted to try working with this display with an oldesp32
microcontroller.In a simple example
I didn't understand how to set my pins for the display, or are they hardcoded in the code and I need to
connect/solder
the contacts as indicated in the commented line?Beta Was this translation helpful? Give feedback.
