Whats the baud rate and pinout on the Wio terminal?

Open twitchyliquid64 opened this issue 5 years ago • 11 comments

Hi!

I'm implementing support for Wio Terminal + WiFi (using eRPC ameba firmware) in Rust.

Can you help me work out what the parameters are for talking to the ameba? In particular, I'm not sure what the baud rate is.

Is this correct?

  • Reset the RTL8720 by bringing PA18 low for 100ms, then high, and waiting 100ms
  • Communicate using NXP eRPC over SERCOM0 in UART mode, with RX on PC24 (Pad2) and TX on PB24 (Pad 0). No CTS/RTS.
  • ? Baud rate 1843200 ?
  • eRPC uses the default codec, default framed transport, default crc16 (starting value 0xEF4A, polynomial 0x1021)
