<![CDATA[GPIO rising/falling events]]>I'm seeking to remotely monitor a solar pump using a Lora unit and AtomS3 Lite, and need to count pulses from a water meter's hall sensor.

I see UIFlow1 provides blocks for capturing events on rising (or falling) GPIO inputs, which is what I need, however UIFlow1 won't work with this hardware. I can't find an equivalent on UIFlow2. Or is the PIN BTN 'is pressed' event effectively the same thing? Or do I need to do this in python?

Adding to my confusion, I get the following from the M5 AI assistant:

3. UIFlow2 Block Configuration
Initialize Pin: Use the "Pin" block (under "Hardware") to set the pin number, mode (IN), and pull resistor.
Set Interrupt: Use the "Pin Interrupt" block to select the trigger edge and assign a handler function (defined via the "Function" block).

Thats exactly what I want...but there is not such "Pin Interrupt" block that I can find.

while there doesn't seem to be a Pin Interrupt block you can just put some code into an Execute mpy code block.

I created an example showing interrupts use on Pins. You can find it in the UIFlow Project Zone called: M5AtomS3_GPIO_Interrupt_UIFlow2.4.0

Thanks
Felix

I would like to create an interupt to detect GPIO pulses for my Temperature Controller.
