<![CDATA[NCIR Hat UIFlow Demo Not Working]]>Hi,
I just put the NCIR Hat into the MStick C, load the corresponding demo in UI Flow and run it.
The unit provide error message: '12C' has no attribute 'begin'.
Try to lead the M5F file from the example at Github, same error message.

Any suggestion what's wrong?

I try to load the the program from EasyLoader, it works well. I guess the problem is not in the Unit but more of with the UIFlow demo program.

We will fix it at V1.6.2(Next Week).

Have a nice day.

Is this going to get fixed anytime soon? Kind of a pain to downgrade for this.

  • Downgrade to 1.5.3: not working
  • Downgrade to 1.4.5.1: YES, it is working :) -- Thanks.

FYI, I have another NCIR sensor, the Unit (with cable), not the HAT.
It works fine in both 1.5 and 1.4 firmwares.

I think there has been a few changes in the I2C functions since version 1.4.5
