ST7735 greenTab settings

[MHz000]

What is wrong with my setup for a ST7735 greenTab?
tft.fillScreen(TFT_BLACK) fills just 1/3 of the screen while
tft.print("0.1 0.2 0.5 1K 2K 4K 8K") works fine and writes a whole line.

Thank.you

It looks like the wrong driver is being used. Run the Read_User_Setup diagnostic sketch and post the results here.

Bodmer first of all I like to thank-you! My goal is to display an audio spectrum using Arduinos FFT lib on a somewhat larger color display like the ST7735 green tab. The environment I'm using is WIN10, Arduino IDE 1.8.13 and PIO using ESP8266 or ESP32 However I've to admit my very limited C++ knowledge and almost no PIO experience :-( What I've done so far: 1 copy source code e.g. game of live into a new PIO folder/project 2 include bodmer/TFT_eSPI^2.3.67 in platformio.ini 3 include file User_Setup_Select as source code into project folder 4 un-comment line 25 now reading: #include <User_Setups/Setup2_ST7735.h> // (line 17 ... define settings in platformio .. I left active. I don't understand the hint in "Tools" but I would like to do as recommended there) 5 include file User_Setup.h as source code into project folder 6 edit User_Setup to: line 41 #define ST7735_Driver line 84 & 85 #define TFT_HEIGHT 320 // ST7789 240 x 320 #define TFT_HEIGHT 240 // GC9A01 240 x 240 line 95 #define ST7735_GREENTAB 7 compile and upload with no problems👍 7 pin definition and wiringBodm seems to be ok as the display show generation after generation 8 however inbetween tft.fillScreen(TFT_BLACK); erases just 1/3 of the screen🤔 Sorry for asking stupid questions All the best Joschen ------------------------------------------------------------------------------------------------------------------ serial monitor output of running Read_User_Setup as Arduino sketch [code] TFT_eSPI ver = 2.2.19 Processor = ESP8266 Frequency = 80MHz Voltage = 3.32V Transactions = No Interface = SPI SPI overlap = No Display driver = 9341 Display width = 240 Display height = 320 TFT_CS = PIN_D-1 TFT_DC = PIN_D5 TFT_RST = PIN_D-1 TFT_WR = PIN_D6 TFT_RD = PIN_D7 Font GLCD loaded Font 2 loaded Font 4 loaded Font 6 loaded Font 7 loaded Font 8 loaded Smooth font enabled Display SPI frequency = 20.00 [/code] Am Do., 13.

Are you sure it's this size (320 x 240) - all the ST7735's I've seen are either 128x128 or 128x160 - interestingly one of the versions I have, have a "greentab" on the screen cover but I was seeing an outline (a set of pixels tha weren't being written to within the library) changing to a REDTAB fixed that - my boards (AZ Delivery) have a red pcb like your's and are definitely only 128x160
