* Add critical section support Allows defining a code block which is executed as a critical section. Supports AVR, ESP8266 & SAMD. * Add receive message buffering When MY_RF24_IRQ_PIN is defined (and connected), a buffer will be used to retrieve & store messages received by nRF24 as fast as possible. This reduces the chance of losing messages due to a busy microcontroller. nRF24 SPI rx message transfer is running from interrupt context when MY_RF24_IRQ_PIN is defined. If this transfer takes too long, serial characters received will get lost. Therefore serial rx is enabled during SPI transfer of nRF messages. Limitations: Only AVR/SAMD & nRF24L01+ combinations can buffer rx messages. nRF24L01+ IRQ pin should be connected to AVR. Tested on W5100- & Serial-gateway. SAMD has not been tested yet! * Fix Doxygen warnings * Fix more Doxygen warnings

* 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.
