Question: Pin Setup Kuman 3.5 Inch

[steffenmllr]

I had a display laying around Info1 Info2 Info3 but I'm not really sure how to wire it and which settings to use. This is what I googled for the display:

1、17               3.3V       ------   Power supply positive (3.3V power input)
2、4               5V         -- ----     Power supply positive (5V power input)
3、5、7、8、10、12、13、15、16    NC         --- ---         NC
6、9、14、20、25                    GND        -------          Power GND
11               TP_IRQ     ------ Touch panel interrupt, detect the touch panel is pressed down to a low level
18               LCD_RS       -------   Instruction / data register selection
19               LCD_SI / TP_SI   ------ LCD display / touch panel SPI data input
21               TP_SO          -----  SPI data output of touch panel
22               RST                -----        reset
23               LCD_SCK / TP_SCK   LCD  --------    SPI clock signal for display / touch panel
24               LC _CS           --------          LCD chip select signal, low level LCD
26               TP_CS    ---------   The touch panel chip select signal, low level selection of touch panel

I'm new to this hardware thing :) I also have a wemos d1 mini and some nodemcu here. What would be the minmal setup just to draw some text on the display? I did use the RPI_ILI9486_DRIVER and it compiled and flashed to the nodemcu but there was nothing on the display.

These are the connections I use for a NodeMCU board (assumes touch display is not used).

• Display SCK to NodeMCU pin D5
• Display MOSI to NodeMCU pin D7
• Display DC to NodeMCU pin D3
• Display RST to NodeMCU pin D4 (or RST)
• Display CS to NodeMCU pin D8
• Display 0V (GND) to NodeMCU pin GND (0V)
• Display +5V to NodeMCU 5V (Vin)
• Display 3.3V(TP_CS) to NodeMCU 3.3V

@Bodmer Thank you! Got it working!
