UIFlow2 & M5Paper

[daniel.edge456]

Hi,

I'm trying to get my m5paper up and running with a basic app to toggle a device.

The code displays temperature, humidity, co2, IAQ Level all correctly, but the touch interaction with the device is not working - any tips? Also, am I correctly implementing the sleep?

Thanks so much in advance!

Hello @daniel-edge456

in UIFlow2 v2.2.6 using touch blocks for M5Paper and then look into the Python tab I get the following code to get touch coordinates:

if (M5.Touch.getCount()) > 0:
  x = M5.Touch.getX()
  y = M5.Touch.getY()

doing the same with power blocks I get:

Power.deepSleep(1000, True)

to put M5Paper into deep sleep.

Thanks
Felix
