So I just got an update pointing me to this option being setup via the adafruit_touchscreen.Touchscreen(). So here are the configurations for each orientation of the screen.

# -------Rotate 0:
ts = adafruit_touchscreen.Touchscreen(board.TOUCH_XL, board.TOUCH_XR,
                                      board.TOUCH_YD, board.TOUCH_YU,
                                      calibration=((5200, 59000), (5800, 57000)),
                                      size=(320, 240))

# -------Rotate 90:
ts = adafruit_touchscreen.Touchscreen(board.TOUCH_YU, board.TOUCH_YD,
                                      board.TOUCH_XL, board.TOUCH_XR, 
                                      calibration=((5200, 59000), (5800, 57000)),
                                      size=(240, 320))

# ------Rotate 180:
ts = adafruit_touchscreen.Touchscreen(board.TOUCH_XR, board.TOUCH_XL,
                                      board.TOUCH_YU, board.TOUCH_YD,
                                      calibration=((5200, 59000), (5800, 57000)),
                                      size=(320, 240))

# ------Rotate 270:
ts = adafruit_touchscreen.Touchscreen(board.TOUCH_YD, board.TOUCH_YU,
                                      board.TOUCH_XR, board.TOUCH_XL,
                                      calibration=((5200, 59000), (5800, 57000)),
                                      size=(240, 320))

Basically the board.TOUCH pins need to be rearranged along with switching the size entries for the 90 and 270 degree rotation.

It would be helpful to add something that selects the correct board.TOUCH pin configurations based on the screen orientation. Maybe a new parameter for adafruit_touchscreen.Touchscreen() called rotation just like it is for Display.

I also suggest adding more detailed documentation for what the parameters are responsible for in adafruit_touchscreen.Touchscreen() something like:

class: adafruit_touchscreen.Touchscreen(x1_pin, x2_pin, y1_pin, y2_pin, *, x_resistance=None, samples=4, z_threshhold=10000, calibration=None, size=None)

Parameters:

• x1_pin (int?) – Data pin for Left side of the screen.
  • Must also be capable of becoming AnalogIn pins.
• x2_pin (int?) – Data pin for Right side of the screen.
  • Must also be capable of becoming AnalogIn pins.
• y1_pin (int?) – Data pin for Bottom side of the screen.
• y2_pin (int?) – Data pin for Top side of the screen.
  • Must also be capable of becoming AnalogIn pins.
• x_resistance (int?) – If you know the resistance across the x1 and x2 pins when not touched,
  pass that in as 'x_resistance'.
• samples (int?) – By default we oversample 4 times, change by adjusting 'samples' arg.
• z_threshhold (int?) – We can also detect the 'z' threshold, how much its pressed. We don't
  register a touch unless its higher than 'z_threshold'
• calibration (tuple) – A tuple of two tuples, the default is
  ((0, 65535), (0, 65535)). The numbers are the min/max readings for the
  X and Y coordinate planes, respectively.
• size (list?) – The dimensions of the screen as (x, y)

There is actually some really helpful notes in the adafruit_touchscreen.py file that would have been supper helpful if I knew they were there.

yes! wanna add something to the readme or example?

I think Adding the more detailed info about the adafruit_touchscreen.Touchscreen() class parameters along with adding that use comments from adafruit_touchscreen.py would be most helpful.

I could also come up with an example for changing the orientation of the display and touchscreen that would let a user uncomment the correct orientation for the touchscreen.

either way is fine by us :)

@RichardA1 Are you still interested in working on this?

I am a bit swamped with other stuff ATM, but I could try to figure it out at some point unless someone else more familiar wanted to give it a go. I am sure I could do it but not nearly as fast as someone with more Python experience.

Just thought it'd be worth linking #8 since it's related and I don't think was ever linked. I'll take a crack at adding this to the library

Edit: I don't actually have the hardware. I'll see about ordering some to do this.

@RichardA1 I could work improving the documentation if you are not planning to. The example with the orientation example was merged. Let me know thanks 💯
