MySensors Library & Examples  2.3.2-62-ge298769
sha256.h
1 /*
2 * The MySensors Arduino library handles the wireless radio link and protocol
3 * between your home built sensors/actuators and HA controller of choice.
4 * The sensors forms a self healing radio network with optional repeaters. Each
5 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
6 * network topology allowing messages to be routed to nodes.
