DC Motor AKA Lego+ not working in uiFlow?

hkubota

Having updated everything (v1.7.2 for the firmware, and using the beta as well as the non-beta v1.4.5 of the uiFlow), I cannot seem to make the Lego+ (AKA DC Motor in the newer UI) work. All I get is "legoBoard not support in uiflow" on the LCD of the M5 Core unit.

I remember it did work a long time ago. What changed, and more importantly: how to fix this?

Hello @hkubota

yes, it looks like Lego+ has been broken in recent firmware as I get the same error on M5Stack Gray or M5Core2 running 1.7.2 firmware. However when I burn 1.4.5 firmware onto my M5Stack Gray I get a different error stating that the Lego module maybe isn't connected (which is correct as I don't have a Lego module).

It might be worth trying to burn 1.4.5 firmware onto your M5Stack and try again.

Thanks

@felmue That actually worked. Not an ideal situation as I cannot use the newer units, but for now the Lego motors turn again which is awesome!
Thanks a lot! I downgraded the UI, but it never occured to me that I should downgrade the firmware too.
