@lukasmaximus Thank you very much. Where can I find your video regarding updating to micropython 1.12?

@robalstona Excellent hint you gave me. I could successfully transfer the files to my device and the coude is running well. Thank you very much for your assistance.

@m5stack Thanks a lot for your advice

onewire and ds18x20 seem not being supported in Ui Flow Micropython. Does anyone know how to integrate onewire and ds18x20 libraries?
Thanks!
