I just started working with my new RainbowHAT and after going through the “getting started” guide (https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-rainbow-hat-in-python) I was not able to get the first touchpad (A) to recognize touch.
I thought maybe it was a fundamental incompatibility with Rasbian Stretch, but after adding the demo code for touchpads B and C, B and C light up the LED as expected, but A still does not. Also, the “Button A pressed” and “Button A released” text does not appear.
Moving to the next step, and issuing the LED control commands, shows that all 3 LED lights (R,G, and B) are functioning correctly.
Are there steps I can take to further examine the HAT or fix the sensitivivity of touchpad A?
