ledc_set_duty(446): channel argument is invalid

  • N

    Hi all,

    got a Fire Bala2 few days ago and I'm closing in on make it balance with MicroPython only. However, some things I cannot grasp, why do I get these message multiple times after machine.reset()?

    E (14036) ledc: ledc_set_duty(446): channel argument is invalid
E (14036) ledc: ledc_update_duty(378): channel argument is invalid

    running on UIFlow_Fire V1.12.7

    Actually there are two green LED at the very bottom, but I haven't found any example to control it. So far pet theory is they just signal power.

    Any feedback is welcome!

    PS: Why is there a shortage on BMM150 in Germany?
