    • M5Atom-RELAY4

      I'm testing the M5Atom-RELAY4 example.

      When I complile, I get
      src/main.cpp:13:11: error: 'class UNIT_4RELAY' has no member named 'begin'

      I can see that "begin" is in the header file. Is there something else I need to do to make the relay.begin() statement work?

    • ATOM RS485 DC/DC Voltage Converter at 4800bps

      Hi,
      I'm developing a device to output NMEA0183 strings on an RS485 interface. Everything is working, except when I try to initialize the serial port for the RS485 interface to 4800, it does not start (not available).

      Serial2.begin(4800, SERIAL_8N1, 22, 19);

      If I initialize it at 9600, it works fine
      Serial2.begin(9600, SERIAL_8N1, 22, 19);

      Does anyone have any suggestions on what I might try?
