Have you tried it? It looks like the configuration should handle setting 9-bit mode, but I have no ability to test it. |

Sorry, no 9 bit support by Micropython fot SAMD51. The STM32 port is the only one which implements 9 bit serial, and it is possible to have it with RP2 PIO scripts. |

Tested with a SAMD21 and it works as well. |

I'm afraid that modification of the MicroPython UART driver is the only way. Because micropython primarily supports 7-bit or 8-bit data frames. |

I made a PR #15787 for UART 9 bit support. |

Many thanks Robert! Unrelated, but have you heard any recent news about Seeed / RTL enabling WiFi for Wio Terminal? Would be great to have WiFi on this as well.... |

Sure. Only someone has to implement the interface between MicroPython and the RTL firmware, which is a larg piece of work. Seeed and RTL will not do it, I assume. AFAIK, they offer a Arduino library, which could be used as a starting point. |

According to the datasheet for the ATSAMD51 (available here)
In Section 34., it says:
I notice that there are specific ports of Micropython (like maybe the STM32?) that also seem to reference 9-bit serial support. Thus my question is does the Micropython port also support 9-bit for the SAMD51?
