Hello guys!

It would be great to have a full list of the LCD connection since I'm trying MicroPython on the board and I guess have to guess some pin connections.

This is how I initialized the LCD. tft.init(tft.ST7735R, speed=10000000, spihost=tft.HSPI, mosi=23, miso=12, clk=18, cs=5, dc=16, rst_pin=17, hastouch=False, bgr=False, width=240, height=320)

I cannot get touch, also the display show only part of the screen.

Can you guys help me out here?

@fa1ke5 by any chance do you know the pinout/connection of the LCD to the ESP32?

fa1ke5 commented 5 years ago

on the titul page image pinout is present you may see p.[4]

@fa1ke5 I've seen the image but it doesn't say the type LCD screen. I'm also looking for the schematic to see the connection of the backlight pin

fa1ke5 commented 5 years ago

display type is 7789, as i know backlight is not managed and connected to 3.3v onboard.
