* 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 sensors forms a self healing radio network with optional repeaters. Each

/**

|
|
* @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.
