<![CDATA[pbhub change Analog to Digital ports?]]>Hi,

I have a pbhub unit: http://docs.m5stack.com/en/unit/pbhub

And what I didn't know: CH4 + CH5 seem to support "analogRead" only. I don't get any values when I read them digital (from an IR module).

Question: is it possible to change the ports from analog to digital somehow? Maybe modify the firmware of the pbhub?

Thanks

Just wanted to ensure I'm not missing a point here.

no, it is not possible. If you look at the schematic you'll see that CH4 and CH5 are connected to ADC6 and ADC7 or the integrated MCU. These two inputs are analog only.

BTW: you might still be able to use the analog value together with a threshold. If the analog value is above the threshold treat is as digital 1 and if it is below the threshold treat is as digital 0.

Thanks
Felix
