Ext.io GPIOs as inputs ?

frexetat

Hello,
does anyone manage to use the EXT.IO unit's Gpios as input ?
There is an example provide for this unit in the M5sticks pro library but it covers only outputs.
there is this thread talking about the same problem ( I got the exact same result) :
https://forum.m5stack.com/topic/4633/extend-i-o-ext_io-how-to-read-inputs-arduino/9

but it doesn't look like it got resolved
Searching online weirdly doesn't goes anywhere, like if nobody would use this unit which is a bit weird.

Any help would be really welcome!

thank you

@frexetat No there is a bug in the code somewhere according to M5Stack. I discovered it after 2 fruitless weeks of code hacking trying to document the device.
