Adafruit ST7789 Wide Angle 240x240
ESP32 DeviKit v4
I'm try to learn how to use the module Display but If I digit this code:
import display
tft = display.TFT()
tft.init(tft.ST7789, miso=19, mosi=23, clk=18, cs=5, dc=27)
tft.clear(tft.GREEN)
the result is a monitor all purple, in addition also the x y coordinates are totally out of range!
if I write:
tft.init(tft.ST7789, miso=19, mosi=23, clk=18, cs=5, dc=27, height=240)
I see only half monitor and the point 0,0 are still out side of monitor..
Where I'm wronging?
Thanks for the help
I have the exact same. For me, the exact range of the screen is (when landscape/landscape_flip):
- x goes from 40 to 279 instead of 0 to 320
- y goes from 53 to 187 instead of 0 to 240
This results in a total different aspect ratio. I dont't like this.
Also the colors are off. Black and white are flipped, the rest is just weird. Even if I try with play around with the bgr
parameter.

I personally did not find any satisfactory solution and I switched to an OLED...
if you find a solution please keep me updated!

I have figured out how to fix the colours with this comment:

In this issue, there is more interesting info. I use a LilyGO ESP32 TTGO, so I couldn't switch the display.
Here is my setup that works just fine:
TFT = display.TFT()
# 320 * 240, but in reality x goes from 40 to 279 and y goes from 53 to 187 -> 239 * 134 --> 1.78 ratio instead of 1.33
# --> 240 * 135
TFT.init(
TFT.ST7789,
rot=TFT.LANDSCAPE_FLIP,
miso=17,
backl_pin=4,
backl_on=1,
mosi=19,
clk=18,
cs=5,
dc=16,
splash=False,
)
TFT.tft_writecmd(0x21)
TFT.setwin(39, 52, 279, 187) # 240 * 135
TFT.savewin()
