50hz triac phase control with zero crossing timing synchronization. 100micro second timing tolerance or better. I ended up porting to Arduino/C++, too many limitations with UIFlow for now, python maybe to slow anyway. UIFlow is a good tool for higher level/basic control.

In UIFlow is it possible to use an interrupt on an input? when I get a sub millisecond low signal on an input I would like to run some code.

Thanks, I see eeprom option when I change ver to beta in UIFlow. Data in is stored as strings, that simplifies things.

How do I delete apps from the app list with the UIFlow firmware loaded?

In UIFlow, how do I save variables to non-volitile memory? When the M5stack starts I would like to load saved variables so I don't have to re set them every time the power is cycled. If there is a blackout I don't want to loose the current settings.

Converts to;

  if bRunFan and bRunFan != bRunFanOld:
    fPvHrs = 0.01
  if bTm6min and bRunFan:
    fPvHrs = fPvHrs + 0.01
  bRunFanOld = bRunFan

Thanks M5stack, this worked.
I didn't want to divide by 10 because I would have to do that everywhere, slow the execution speed, its a slippery slope. The esp32 has very long divide instruction time compared to addition and multiplication.

How can a make blockly keep a data type? this Function doesnt work, because 0.1 rounds down to 0 every time the code is executed. It is for an hour meter, I want to add 0.1 every 6mins.
This is what blockly automaticaly generates;

if bTm6min and bRunFan:
    fPvHrs = (fPvHrs if isinstance(fPvHrs, Number) else 0) + 0.1

When i manually change the code the problem goes away until blockly reverts back to the old code again.

fPvHrs = fPvHrs + 0.1

@m5stack Its ok thanks, problem solved. I gave the text label the name 'btnA' which is already a M5stack function, so renamingthe label cleared the problem.

@birdsong said in Button Error:
Solution:
I gave text a label btnA, when I changed it to labelA that bug was cleared.

Mine took 5 days to arrive in QLD through digi-key.

What do you think is causing the error "'M5TextBox' object has no attribute 'wasReleased'" to display on the screen when I download the program to a M5stack?
