No image drawn on ST7789

[dfpreda]

Hello! I really liked your peephole project and rushed to buy the ttgo board, but i can't seem to make it work. I succesfully flashed your code using arduino ide (wifi credential changed and uploaded right away) but it doesn't want do display the live feed on the 1.3 inch display (i only have the backlight on). The wifi part works and i can get still images using the http app.(no stream) Could i have a newer board version with different pinout (v2.1)? I bought it from the same seller you did and it looks exactly the same.

Any help would be really appreciated as i really want to finish this interesting project.

Thank you!

Hy pred4nie,

download the latest version of TFT_eSPI (2.3.60)

then comment in TFT_eSPI/User_Setup_Select.h:
#include <User_Setup.h>

and uncomment:
#include <User_Setups/Setup44_TTGO_CameraPlus.h>

after that comment(or delete) in ESP_DoorCam.ino:

// Config for TFT_eSPI (User_Setup.h)
#define ST7789_DRIVER // Full configuration option, define additional parameters below for this display
#define TFT_CS 12 // Chip select control pin D8
#define TFT_DC 15 // Data Command control pin
#define TFT_RST -1 // Reset pin (could connect to NodeMCU RST, see next line)
#define TFT_BL 2 // LED back-light (only for ST7789 with backlight control pin)
#define TFT_MISO 22

#define SPI_FREQUENCY 80000000
#define SPI_READ_FREQUENCY 20000000
#define SPI_TOUCH_FREQUENCY 2500000

and

tft.setSwapBytes(true);

now it should run ;)

@ElPolloDiabloGDC Thank you! You're my hero! Never thought i'd see it work. Have you succeeded starting the web stream too? I'll try bodging together some code even though i don't understand most of the stuff, wish me luck

[ElPolloDiabloGDC]

you are welcome. yes web stream works too. u have to put in your wifi credentials at line 50, 51.

// WiFi Credentials
const char* ssid = "";
const char* password = "";

if u open the serial monitor(@115200 baud) in the arduino app, u will get the cam ip.
