ESP32-C3 (arduino-esp32) display on ST7735 SPI TFT using Adafruit ST7735 and ST7789 Library
This video show how Espressif ESP32-C3-DevKitM-1
(arduino-esp32) display on
1.8" 128x160 ST7735 SPI TFT, using Adafruit ST7735 and ST7789 Library.
Install Library
In Arduino IDE, open Library Manager to install "Adafruit ST7735 and ST7789 Library by Adafruit" and other library dependencies.

Hello good morning;
ReplyDeleteSorry, my English is Google.
I have a sp32 -S board "https://99tech.com.au/product/esp32-s3-yd/" this one.
I try to connect a screen "ST7735 Full Color LCD Module"
this "https://es.aliexpress.com/item/4001144194129.html?spm=a2g0o.order_list.order_list_main.178.3b36194dR8JKZ2&gatewayAdapt=glo2esp" 1.44 128x128 rgb_tft
with the library "Adafruit ST7735 and ST7789 Library > graphicstest" and it does nothing with another ESP32 not S3 and with different pins it works but following your example it has not worked for me
can you help me??
many thanks.
try this configuration // tradeoff being that performance is not as fast as hardware SPI above.
Delete#define TFT_MOSI 5 // Data out
#define TFT_SCLK 17 // Clock out
#define TFT_CS 15
#define TFT_RST 26 // Or set to -1 and connect to Arduino RESET pin
#define TFT_DC 14
// For ST7735-based displays, we will use this call
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);
Hi!
ReplyDeleteWhere did you get that Arduino sketch: "get_spi_info.ino"?
Thanks!
