hi all,need to connect 2*lcd 1602 and st7789 on to nano

lcd displays
hi need to wire togther 2* 1602 and 1* st7789(240240),they both work independly
the 2
1602 with 0x26 and 0x27 addresss. ic2 SDL PIN 13,SDA PIN 11 (correct shown running scan.ino)
#include <LiquidCrystal_I2C.h>

the st7789 works alone <Arduino_ST7789.h> // (nothing shown running scan.ino)
//no jumpers found on pcb
#define TFT_DC 9
#define TFT_RST 8
//SDL PIN 13,SDA PIN 11
Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST);
running scan.ino shows 0x26 and 0x27 but when all 3 displays no address’s found,
i understand the 1c2 protocol but should it mix with spi,
thanks all…

Please be more specific.
i.e. which Nano. there are Nano boards with mega328P, mega4809, NRF ARM chips, …
e.g. which ST7789 board. post link to Ebay sale page
e.g. which 16x2 LCDs.

A lot of popular items are recognised by the readers. e.g. “Nano-328P” or “Blue 16x2 LCD with I2C backpack”
But it eliminates guesswork if you post links to the actual items on your desk.

Please edit your post for typos. e.g. SDL

Either post a schematic (pencil drawing is fine)
Or describe each wiring connection accurately.
