[SOLVED] Itead Rboard 2.1.1

  • Hi,

    I've been using Mysensors for a long time without need to update from version 1.4! 🙂

    Most of my nodes are mains powered and use relay's for switching lots of different stuff. Recently I have updated my serial gateway, uno's and nano's to 2.1 without problem, however, not so lucky with the Itead Rboard. @gregl helped me last time by showing me how to reference pins 8 & 9 for CE/CS. Could someone please help me understand what I must modify in a sketch using version 2.1.1?

     * The MySensors Arduino library handles the wireless radio link and protocol
     * between your home built sensors/actuators and HA controller of choice.
     * The sensors forms a self healing radio network with optional repeaters. Each
     * repeater and gateway builds a routing tables in EEPROM which keeps track of the
     * network topology allowing messages to be routed to nodes.
