On web, just choice block type.

For code, add return description like this:
def func(self) -> int:
return 0

Check your web browser and OS screen settings

Hello,
In case you don't have an answer here is an example of custom block I made for Parsing Text. It will ask for 3 inputs (via variables) and then return a result to a variable

Don't forget to use the ${} to reference your "Variables" when creating the formulas. It also reminds you when in the block creater.

This is what it looks like in UIFLOW. Note the 1st three are inputs and "DataResults" is the output. In my UIFLOW example DataParse and DataResults are UIFLOW variables not the same as the Custom Block variables

@m5stack The link was in the Flow UI.

The User Manual Button under the Create and Open file buttons.

@gaviota I confirm that I found the problem you described also on the on-line version 1.7.0 of UIFlow. Thanks to your trick (click on each block again in Black-Maker will fix the proper rendering once imported into UIFlow) I was able to rescue.

@world101
Thank you for the fast answer,
"strg - works" :)

Thank you! I'm continually impressed with your rate of development!

thank you.
It is indeed not an I2C but analog (stupid of me)
I removed the double post

Thanks! Yeah, one can't scroll down to it: You have to have a display that is big enough (or a resolution high enough) to see it.
