  Oh, one more question from the "dumb questions about I2C" department... Could I plausibly run I2C to the PPS at an otherwise ridiculously low clock rate and expect it to work? i.e. is it a valid troubleshooting technique to set the I2C rate down to something like 1 kHz (or even lower) to see if that dodges some timing sensitivity? The components involved definitely ought to be capable of much higher bit rates, but as it turns out I never expect to actually exchange more than a few dozen bytes with this thing under real conditions -- its programming protocol is extremely simple. So communicating at a very low bit rate is definitely acceptable from a pure functionality perspective.

  @djairguilherme said in New ESPHome Support for M5StamPLC:

  Thanks ChirpyChips aka @Beormund.

  I used your implementation with ESPHome to interface with a Schneider Phase Inverter. I wrote a tutorial on Hackster.io.

  Thank you very much for your work!

  @djairguilherme Nice! At some point I really do need to utilise ESPHome's RS-485 support to expose the M5StamPLC's PWR-485 interface as a Modbus slave. It's on my TODO list.

  Right, so I never received a response. I know I can get a new base, but I really only want the battery as a base will add extra bulk to the unit.

  Hello @xgonc

  no, I did not try any other Ethernet library.

  Thanks

  The error means I2S port 0 driver wasn’t installed before uninstall was called. Make sure you call i2s_driver_install() successfully before attempting i2s_driver_uninstall(). Also, check that your code isn’t trying to uninstall the driver twice or uninstall before install. Reviewing the initialization sequence and adding error checks after install calls should help fix this issue. If you’re using legacy I2S, consider updating to the latest driver APIs for better stability.
