@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. https://www.hackster.io/nicolaudosbrinquedos/m5stack-stamp-plc-as-real-plc-3ec3ed 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.

@karlfr I saw this on Facebook! The Dial is a more powerful and capable controller than the Mega. Just use the Dial, but be aware that it is only 3.3V, and will be damaged if any pin receives 5V

using the mentioned changes hello_world example did compile and got uploaded to my core2. However , nothing is shown on screen, screen remains black.

Hi Vielen Dank für die Antwort bin mittlerweile einen Schritt weiter. Aber sobald ich den Button drücke kommt jetzt zuerst ein A und danach tauchen lauter 255 auf und der Drucker druckt lauter Chinesische Zeichen.
