The usage example may only work for 2.2", 2.4", 2.8", 3.2" TFT ( which I could not verify ). With 1.14" TFT and raspberry pi 4, the wiring are different, chipset is different. At the first try-out, as a novice user, I was doubting my soldering skills. Why does not it work? Blank screen! It turns out that wrong chipset driver was used. After updating its chipset driver, it is still blank! I was doubting my connections and my soldering skills again! It turns out that the CS_PIN, DC_PIN are not the same as bigger TFTs. After all those adjustments, it worked.
with this fix, the blue rectangle will situate at the corner near Vin pin.

Please do a squash merge! I missed x and y offsets after verifying it on my display. |

Here is the display in action:

Hi, thanks for adding this. For the guide link, perhaps change it to https://learn.adafruit.com/adafruit-1-14-240x135-color-tft-breakout/python-wiring-and-setup since you are specifically mentioning the 1.14" display. It's a mirror of the same page you linked to, but is in the 1.14" guide in case users want to see other related pages.
address review feedback.

Well spotted! |

After referencing the great example, it worked. Hence, could I save a few hours of next 1.14" TFT users please?
