Can anyone help me map a latching button/switch to the 'Map' function? I'm assuming this is available since it's called out in the comments of the ControlPacket struct (see below: byte Mode) in KSPIODemo6. However, I can't find a reference to "Mode" anywhere else - unless I'm just missing it... struct ControlPacket { byte id; byte MainControls; //SAS RCS Lights Gear Brakes Precision Abort Stage byte Mode; //0 = stage, 1 = docking, 2 = map unsigned int ControlGroup; //control groups 1-10 in 2 bytes byte AdditionalControlByte1; //other stuff byte AdditionalControlByte2; };
