/*
 * 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.

/**
 * @def MY_CRITICAL_SECTION
 * @brief Creates a block of code that is guaranteed to be executed atomically.
 * Upon entering the block all interrupts are disabled, and re-enabled upon
 * exiting the block from any exit path.
 * A typical example that requires atomic access is a 16 (or more) bit variable
 * that is shared between the main execution path and an ISR, on an 8-bit
 * platform (e.g AVR):
 * @code
 * volatile uint16_t val = 0;
 *
 * void interrupHandler()
 * {
 *   val = ~val;
 * }
 *
 * void loop()
 * {
 *   uint16_t copy_val;
 *   MY_CRITICAL_SECTION
 *   {
 *     copy_val = val;
 *   }
 * }
 * @endcode
 * All code within the MY_CRITICAL_SECTION block will be protected from being
 * interrupted during execution.
